Product catalog summary
Overview
The document outlines the technical specifications and configuration details for the TBX 50 series of electro-magnetic encoders by TWK-ELEKTRONIK GmbH, designed for single-turn applications. It covers various models with different electronic interfaces, including the TBN 50 model with a CANopen interface.
Construction

Electro-magnetic Encoders TBB 50 - BISS-Interface Bidirectional Serial Interface - 12 Bit / 360°Technical data Function Biss is a serial sensor interface protocol for synchronous, fast and safe readout of sensor data, as well as for bidirectional access to the sensor registers. The interface is hardware-compatible with the SS/ - interface and has two or more unidirectional lines. A system consists of a controller (master) and one to seven sensor (slave), which can be in a serial or semiparallel connection. For either type of connection the 'MA' line, originating from the master, is connected...
