Hazardous-area encoder

Designed for hazardous areas, the 78E Series Ex Encoder’s “flameproof enclosure” has ATEX and IEC Ex international approval in addition to third-party approval by TÜV.

The encoder is available in wide range of interfaces, including SSI, CANopen, DeviceNet, or Profibus, and has a removable cover to allow easy configuration and connection to a PLC.

The unit’s modular design makes maintenance simple because the rotary encoder can be replaced independently of the cable. For fieldbus versions, bus coding takes place in the connection cover.

These rotary encoders feature a 78-mm-diameter housing in either anodized aluminum or stainless steel. For the mechanical connection, users can select between a clamp and synchro flange. The encoders deliver maximum speeds to 3,000 rpm and operate at –40 to 70°C.
