The ECN/EQN/ERN 400 series rotary encoders are promoted as being especially useful in applications where quick machine shut-off is required in dangerous situations. Featuring a shaft coupling which provides mechanical fault exclusion for connection to the customer’s machine shaft, they are useful in safety-related applications up to SIL 2 PL d category 3 levels. The encoders are available with a blind hollow shaft or a hollow through shaft with a choice of a 10-mm or 12-mm diameter. Available with either EnDat 2.2 or DRIVE-CLiQ absolute serial interfaces or an analog 1 VPP output, encoders using the EnDat2.2 and Drive-CLiQ outputs will additionally feature an internal temperature sensor integrated in the encoder electronics as well as an evaluation circuit for an external temperature sensor to use for evaluation of the motor temperature.
