The encoder transforms rotational movement into pulse sequences. These allow the measurement of linear distances and angular movement as well as the determination of positions.
Electrical connection
Disconnect power from the installation before connecting or disconnecting cables or connectors!
Unused wires must be insulated to avoid short circuits and cross faults.
Short-circuit protection
5 V TTL version: outputs short-circuit protected against 0 V
10...30 V HTL version: outputs short-circuit protected against 0 V
and L+ for maximum 1 minute

Wiring is also indicated on the housing cap. If there is a deviation, the encoder must be connected as indicated on the label on the housing cap.
The wires L+ (sensor) and 0V (sensor) are internally connected to the supply voltage. When using external electronics which regulate the supply voltage these wires can be used as test wires. If unused, these wires must be connected to the supply voltage or insulated.
Depending on the version, the electrical connection is made via the cable or via cables to be obtained separately.
When using suitable cables the maximum cable length is 100 m for the 5 V TTL version and 300 m for the 10...30 V HTL version.
The cables must be laid separately from interfering sources, the minimum distance is 20 cm.
The braided screen in the cable is connected to the encoder housing.

180° 180° 90°The encoder provides digital pulse sequences at the output stages.
The outputs A and B are electrically offset by 90^ . Thus the direction of rotation can be evaluated in the external electronics.
The combined zero index is provided once in a mechanical revolution of the shaft. In case of power failure it can be used as a reference point within a revolution.
The inverted output signals are used for external electronics with differential voltage input to filter interference.
Installation
Do not hit the shaft, do not use a file or similar tool on the shaft: This could destroy the unit!
The encoder can be screwed to the angle bracket. The shaft should be connected using a flexible bellows or spring disc coupling to compensate for shaft displacement and to protect the encoder against damage.
Linear movements can be transformed into a rotational movement using a measuring wheel or rack and pinion. For mounting the maximum permissible shaft loads of the encoder must be taken into account.
Mounting the angle bracket on a resilient base protects the encoder against too high a stress due to roughness of the material.
