POSITAL introduced its heavy-duty absolute rotary encoders that feature shock- and vibration-resistant magnetic measuring elements housed in 316L stainless steel housings. Designed for rugged environments, the encoder features seals on the shaft entry and cable connection (IP68 and IP69K level protection), and shafts that can withstand mechanical forces of up to 300 N (67 pounds).

The magnetic encoders contain 13-bit resolution (8192 steps per revolution) and multi-turn models are available with a range limited only by memory size. Its internal rotation counter uses a self-powered technology that enables these devices to keep track of their absolute position even when movement occurs during control system power outages. The encoders are available with a simple serial (SSI) interface or CANopen, DeviceNet and SAE J1939 field bus interfaces. Analog interfaces (4-20mA or 0-10V) are also available.
