A positive-locking mechanical connection between the cus-tomer’s shaft and the sensor shaft ensures that the magnet in the sensor shaft precisely reflects the rotation of the cus-tomer’s shaft. With the TBN model, one rotation (i.e. max. 16,384 steps) is recorded.With the subsequent absolute transmission, the TRN shaft encoder reaches a measuring range of up to 4096 rotations. The position and speed values (PDO - Process Data Object) are output via the CANopen protocol.

A CAN controller at the output enables integration into the CANopen network. According to CANopen Application Layer and Communication Profile, CiA Draft Standard 301, Version 4.1 and "Device Profile for Encoders CiA Draft Standard Proposal 406 Version 3.0" and CANopen Layer setting Services and Protocol (LSS), CiA DSP 305.

The angle transducers have a magnetic scanning according to the HALL principle. Due to the robust design, critical and interference-free applications in harsh environments can be realized. They have a robust housing (wall thickness > 5 mm) made of aluminium or stainless steel, shaft and ball bearing made of stainless steel, shaft with flattening, rotor with shaft and permanent magnet mounted in prechamber, sensor circuit consisting of ASIC with Hall elements and interface electronics housed in closed main chamber. Two models are available: For low and high temperature applications. The model for low-temperature use is equipped with a special grease for bearings and shaft seal. Seals and shaft seal are made of PTFE. Cable gland with clamping jaw pressure screw and silicone seal. The high temperature model is without shaft seal. Under the rear cover, there is a signal path switch (CW/CCW). On the side there is a preset button (4 mA) placed under a screw plug.

Robust case with wall thickness of 5 mm either in seawater resistant aluminum or in stainless steel - shaft in stainless steel - rotating components with permanent magnet in front chamber - electronic circuit with ASiC and Hall elements and interface components fitted within main chamber, separated from rotating components by a metallic wall - integral counter for the acquisition of revolutions, with non - volatile storage - optional potting against water jets (IP 69K) - electrical connections via round plug or lead exit.

Robust aluminium case - Stainless steel shaft, Ø 10f7 shaft with flat (9 -0.1 mm), RS bearing with NILOS ring - Potted housing for IP 69K protection - Electrical connection via 2 sensor plugs (M12 plug, 5-pin, pins) for bus 1 and bus 2. One hex rotary coding switch each for setting the address under the blind plug

Recording of the angular position by means of a Hall sensor and signal processing including generation of the output signal - in addition to the angular position, a speed signal can also be output in digits / time unit - electrical connection via screw clamp (5-pin, conductor cross-section max. 0.5 mm²) or PTFE pigtail connector, 300 mm long - a CAN controller at the output enables connection to the CANopen network. According to CANopen Application Layer and Communication Profile, CiA Draft Standard 301, Version 4.1 and according to Device Profile for Encoders CiA Draft Standard Proposal 406, Version 3.0 and CANopen Layer setting Services and Protocol (LSS), CiA DSP 305. In the multiturn version, the number of revolutions is recorded in a counter. The position value is saved on shutting off the supply voltage. In voltage-free condition, the position value is recorded on movement of the shaft in a range of ≤ ± 90°.

A positive mechanical connection between the customer shaft and the sensor shaft ensures that the magnet of the sensor shaft accurately reproduces the rotation of the customer shaft. The TBE measures one revolution, i.e. a maximum of 16,384 steps/revolution. With the trailing absolute gear, the TRE rotary encoder achieves a measuring range of up to 4096 revolutions. The zero point and the code progression can be set or changed via the inputs 'Set input' and 'Codevelauf' (each input circuit E1).
