The 78E Series Ex Encoder from Pepperl+Fuchs is especially designed for applications in hazardous areas. The 78E Series with its “flameproof enclosure” has ATEX and IEC Ex international approval in addition to third-party approval by TÜV. It is designed for the oil/gas, refineries, mining and material handling (agriculture, chemicals) industries. The new 78E Series is available in a wide range of interfaces, including SSI, CANopen, DeviceNet or Profibus. Along with these different protocols, this encoder series has a removable cover that allows easy configuration and connection to a PLC, the company says. These hazardous area rotary encoders feature a compact 78-mm diameter housing available in anodized aluminum or stainless steel. For the mechanical connection, users can select between a clamp and synchro flange. They deliver maximum speeds to 3,000 rpm and are designed for a temperature range of -40 to 70 degrees C.
