Heidenhain Functionally safe hollow-shaft encoders

These functionally safe hollow-shaft-connection encoders, called the ECN/EQN/ERN 400 series, are useful in applications in which quick machine shut-off is required in dangerous situations. Featuring a shaft coupling that provides mechanical fault exclusion for connection to the customer’s machine shaft, these rotary encoders are suitable for use in safety-related applications up to SIL 2 PL d Category 3 levels. They are available with a blind hollow shaft or a hollow through-shaft with a choice of 10- or 12-mm diameter. The encoders are offered with either the EnDat 2.2 or Drive-CLiQ absolute serial interfaces or with an analog 1-VPP output.
