Pepperl+Fuchs Launches New Hazardous Area Encoder

The new 78E series Ex encoder from Pepperl+Fuchs was designed for applications in hazardous areas. The 78E Series with its flame-proof enclosure has ATEX and IEC Ex international approval in addition to third-party approval by TÜV.

pepperl0114It was designed for the oil/gas, refineries, mining and material handling (agriculture, chemicals) industries. The new 78E Series is available in wide range of interfaces, including SSI, CANopen, DeviceNet, or PROFIBUS. Along with these different protocols, this encoder series has a removable cover that simplifies configuration and allows for connection to a PLC.

Another feature of the 78E rotary encoder is the modular design with removable connection cover. The connection covers are supplied either with a cable or with only a certified cable gland, providing the option of customized cabling.

The modular design may simplify maintenance because the rotary encoder can be replaced independently of the cable. For fieldbus versions, bus coding takes place in the connection cover. This means that the user can program the relevant address on site and set the terminator if required.

These hazardous area rotary encoders feature a 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 3000 rpm and are designed for a temperature range of -40 degrees Celsius  to 70 degrees Celsius.
