HEIDENHAIN announced that its ECN/EQN 400 series of rotary encoders now offer PROFIBUS and PROFINET interfaces and feature a rugged blind hollow shaft, with a 12mm diameter. Both the models ECN 413 and EQN 425 rotary encoders are resistant to shock (6 ms) up to 1000 m/s2 and vibration up to 100 m/s2 in accordance with DIN. Providing protection to IP 64, they are designed for an ambient temperature range from –40 °C to +70 °C in accordance with DIN with shaft speeds up to 6000 rpm.

In regards to connectivity, users of these encoders 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. Both the ECN 413 and EQN 425 function with PROFIBUS-DPV0, DPV1, DPV2, and PROFINET interfaces.
