Play-free electronic switching cam
encoders - NOC series
CANopen / SSI / analogue
Compact and robust for automation in
mechanical and plant engineering
The new play-free electronic switching cam encoder
model range makes two of the control signals most frequently required in automation technology available in
one single compact device:
n
One digital or analogue rotary encoder signal
n Up to four galvanically separated relay
switching outputs
The devices operate without play, meaning that the
relay switching outputs switch precisely at the set angle
positions without reversal play as they obtain digital
position information from the integrated rotary encoder.
The rotary encoder signal and the switching outputs
can be parameterised and referenced. A robust aluminium housing and a high protection type enable use in
stressful environments.
