Presentation

ETx25 encoders are suitable for applications where a long lifespan and optimal adaptability of the sensor to the application are important.
The ETx25 family of Hall-effect encoders is characterized by its high reliability as well as lifespan of over 100 million revolutions and an independent linearity of up to ±0.3%. The encoders detect angles without contact and have a highly hardened and tempered metal sleeve bearing. The sensor in Ø25 mm housing with Ø6 mm or 6.35 mm (1/4 ") shaft is fixed in the application by means of a central thread. A comfortable selection of electrical connection possibilities via solder, - clamp, - round, - or flat ribbon cables are available. It can be chosen between following electronics:

ETA25 singleturn absolute encoder (ETA25X redundant version):
Provides an absolute analogue signal with 12 bit resolution. For safety and critical applications, the ETA25X offers a galvanically isolated and redundant electronic (see ETA25X series in the data sheet).

ETA25PM, Teach-In-Encoder, programmable multiturn or singleturn absolute encoder:
Field-Programmable (Teach-in)-Encoder for angles of rotation up to 72000° (200 revolutions), can also be used as a singleturn encoder with Teach-in. Resolution 12 bit, with current or voltage output. Teach-in can be performed on site using a simple programming circuit.

ETI25 singleturn incremental encoder:
With up to 1024 pulses / per revolution and availability of following output signals: TTL, Push-Pull or Open Collector

ETS25 serial singleturn angle encoder:
14 bit resolution with SPI interface, redundantly available for SPI (ETS25X series)

ETP25 PWM singleturn encoder:
With PWM output
