Hollow-Shaft Encoders Provide Functional Machine Safety

Description

Called the ECN/EQN/ERN 400 Series, these new rotary encoders are especially useful in applications where quick machine shutoff is required in dangerous situations.

 

Featuring a new shaft coupling which provides mechanical fault exclusion for connection to the customer’s machine shaft, these encoders are of particular 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.

 

Encoders will be offered with either the EnDat 2.2 or DRIVE-CLiQ absolute serial interfaces or even an analog 1 VPP output.
