With the laser analog light barriers of A-LAS Series parallel laser light with homogeneous light distribution in round or rectangular cross-section is used for measuring, positioning, and detection of objects starting from a size of 0.01 mm.

The A-LAS light barriers work according to the following measuring principle: The laser light beam that is emitted by a high-precision optical unit (aspherical surface made of glass) allows the detection of smallest objects (e.g. threads) even in case of a large transmitter/receiver distance (distances up to 100 m, depending on model and aperture). The use of high-precision apertures in the transmitters ensures optimum adaptation to the respective application. The aperture guarantees a homogeneous light distribution on the beam and a sharp beam limitation. Apart from a large variety of standard apertures special apertures can also be realised.

The laser digital light barriers of D-LAS series work with visible parallel laser light. The use of round or rectangular apertures ensures a homogeneous light distribution in the laser beam. Smallest objects are detected even in case of a large transmitter/receiver distance. Dynamic correction of the switching threshold compensates the effect of dirt accumulation (with D-LAS1, D-LAS2, D-LAS-34, D-LAS-34/90).

These light barriers are ideal for positioning tasks.

TR-Electronic rotary encoders with optical or magnetic scanning precisely acquire position in steel production, wind power plants, cranes and ships as well as in explosion-proof versions in painting lines. Miniature versions ensure the correct position in medical technology and SIL3 approved absolute rotary encoders ensure the necessary safety.

In addition to high-quality rotary encoders for almost every application, we also offer extensive accessories such as programming tools, displays and assembly components for quick and simple commissioning and seamless integration into your processes.

From linear absolute measuring systems through to laser distance measurement

TR-Electronic linear encoders acquire linear movements in machines, tools and installations according to your specific requirements with different technologies.

Linear absolute position measuring systems and position sensors (magnetostriction) measure linear movements e.g. in injection molding machines without contact and wear-free, or are integrated directly into hydraulic cylinders. Cascadable position sensors position parting units. High-resolution absolute position measuring systems with a glass scale ensure precise positioning on machine tools. And laser sensors based on phase difference measuring techniques position aisle stackers in the desired position extremely precisely in warehousing and materials handling technology.

With TR-Electronic linear rotary encoders you can measure paths virtually wear-free and precisely move your machines and installations to the desired position. As a result you will increase the availability of your installations and guarantee efficient production processes. You will prevent expensive production downtimes and prolong the lifetime of your machines.

The laser light barriers of F-LAS series allow the solution of complex problems (curve discussion, tolerance band monitoring, etc.).

Functional principle: The signal at the analog output decreases proportionally with increasing laser beam covering

Collimated laser beam:
The laser light beam that is emitted by a high-precision optical unit allows the very precise detection of smallest objects (e.g. threads) even in case of a large transmitter/receiver distance.The low divergence of the light beam almost completely reduces the measuring error that is caused by moving the measuring object from the transmitter in the direction of the receiver.

Homogeneous light distribution:
The use of high-precision apertures in the transmitter ensures optimum adaptation to the respective application. Apart from a large variety of standard apertures special apertures can be realised. The aperture ensures an homogeneous light distribution in the beam and a sharp beam limitation.

Monitor signal:
In addition to the switching signal the fork light barriers of series F-LAS also provide an analog signal. “Monitoring” of the analog voltage allows a better evaluation of the switching signal. The output can also be used for measuring tasks.

These sensors mainly are characterised by their high switching frequency (typ. 25 kHz in case of line F-LAS-DC, and typ. 200 kHz in case of line F-LAS-DC-HS), the large variety of fork sizes and apertures, and their high switching accuracy.

The F-LAS laser fork light barriers are ideal for positioning tasks.

Fork light barriers of the FIA series primarily are chosen for high-precision trigger applications. They are frequently used in the stamping industry. Because of their compact and very sturdy design they are generally used in rough industry environments. In the fork light barriers of the FIA series the complete electronic evaluation unit is integrated in the sensor housing. The visible light beam makes it considerably easier to adjust the light barrier. The switching state is indicated by a red/green LED.

In the FIA-A version the focus lies on high positioning accuracy, the temperature-compensated analog output provides a voltage that is proportional to the aperture’s degree of covering. Various rectangular apertures are available.

The laser fork light-barriers of the FIA-L series primarily are used in the field of stamping for feed measurement and for the exact checking of small parts at high feed rates.

These sensors mainly are characterised by their high switching frequency (typ. 10 kHz), their compact design, and their high switching accuracy.

• Intelligent compact drives integrate absolute rotary encoder, motor and control technology

  Different batch sizes, huge product diversity, the individualization of production and maximum cost efficiency are central requirements on modern production processes. In order to cope with these requirements, secondary functions are increasingly being electromechanically automated in machines and systems, in addition to primary processes.

  TR-Electronic’s fieldbus-capable encoTRive compact drives make this possible – in machine construction and machine tools as well as in the packaging, press, woodworking, glass, printing, plastic and textile industries. These compact drives have no external electronics. They integrate actuator, sensor and control technology in one housing: control logic, position, speed and torque controller, power electronics and absolute rotary encoder. These compact drives can communicate with the PLC via fieldbus. Further components such as transmission, holding brakes or I/Os are added, depending on the application.

  On the basis of the encoTRive communication and controller platform both simple control applications
  and complex machine processes can be automated efficiently and consistently with different drive types
  – simply, flexibly and cost-effectively.

Fiber optics (optical fibers) offer solutions for difficult tasks in optoelectronis and are primarily used wherever compact devices are too big, too heavy, or technically unviable.

Advantages:
– Universally applicable

lenses) and further accessories available – Optionally vibration protection
– Special designs

The frame light barriers of FLB Series are used for the measurement of smallest unguided parts.

The frame light barriers of FLB Series are extremely insensitive to outside light due to optical filtering and partly modulated operation.Still they guarantee safe measurement of parts with sizes starting from only.

0.2 mm. An impact protection facility (aluminum baffle plates and rubber-metal vibration dampers) protects the optical unit of the frame light barrier against impacting parts.

With its compact design and with the remote control unit (in case ofFLB-FR3) this type of frame light barrier is excellently suited for eject monitoring in a punching die, for example.

High sensitivity due to threshold correction:
By continuously monitoring the maximum value at the receiver a dynamic switching threshold correction compensates the effect of dirt accumulation. Increasing dirt accumulation therefore does not lead to change of sensitivity.

Functional principle:
The optoelectronic components of the transmitter and receiver units are arranged opposite to each other in the frame (in the sides in case of fork or split design). Both the transmitter and the receiver unit consist of a row of IR transmitter diodes or phototransistors, which form a homogeneous light curtain between the transmitter and receiver unit.If a measuring object now passes through this light curtain, part of the light band is covered, and less IR light thus impinges on the receiver unit. The signal generated by the phototransistors is then attenuatedand differentiated proportional to the impinging quantity of light, and the differentiated signal is sent to a comparator pulse lengthening unit.

Parameterisable under Windows® (with FLB-CON8): The products FLB-F, FLB-H, and FLB-V of the FLB Series can be connected to the electronic control unit FLB-CON8. The electronic control unit guarantees a stable voltage supply for the respective transmitter/receiver of the FLB Series.

The electronic control unit also amplifies and processes the analog signal of the receiver in a suitable manner. A micro-controller performs 12-bit analog/digital conversion of the analog signal, allowing recording and evaluation of the signal characteristics at the sensor. Furthermore the electronic control unit offers various options for intelligent transmitting power control (dirt accumulation compensation) at the sensor.

Parameters and measured values can be exchanged between the PC and the electronic control unit through either the RS232 interface or Ethernet interface. All the parameters can be stored in the non-volatile EEPROM of the electronic control unit through the interface.

The Windows® PC software FLB-TLB-CON8-Scope facilitates parameterisation, diagnostics, and adjustment of the sensor system (oscilloscope function). The software furthermore features the function of a data recorder that automatically records data and saves them on the PC’s hard disk. Firmware updates can be easily performed through the RS232 interface even when the sensor system is installed.
