Fieldbus encoders feature hollow-shaft design

April 9, 2013

Heidenhain offers the ECN/EQN 400 series rotary encoders with Profibus and Profinet interfaces for use in manufacturing and process automation. The encoders feature a blind hollow shaft with a 12-mm dia.

Both the models ECN 413 and EQN 425 rotary encoders resist shock up to 1,000 m/s2 and vibration up to 100 m/s2 in accordance with DIN. Providing protection to IP64, they are designed for an ambient temperature from –40 to 70 degrees C in accordance with DIN, with shaft speeds up to 6,000 RPM.

Users can choose between three radial M16 cable glands or three radial M12 connectors. Node addresses are set via rotary decimal switches concealed by the encoder end plate.
