Discrete Output Mode

• Discrete sensors feature normally-open/normally-closed

PNP outputs.

• Includes two teachable set points and multiple output

functions.

• The upper and lower sensing range can be scaled to a

distance-fixed window.

• The sensor is taught using an easy four-step remote teach

process or an optional programming cord.

Solid-state devices can be susceptible to

radio frequency (RF) interference

depending on the power and the frequency

of the transmitting source. If RF

transmitting equipment is to be used in the

vicinity of the solid-state devices, thorough

testing should be performed to assure that

transmitter operation is restricted to a safe

operating distance from the sensor

equipment and its wiring.

IMPORTANT

ATTENTION

If a hazardous condition can result from

unintended operation of this device, access

to the sensing area should be guarded.
