PRCM12-2AO Autonics Inductive Proximity Sensor
Autonics PRCM12-2AO Inductive Proximity Sensor – M12, 2 mm, AC 2-Wire, NO (Connector Type)
Autonics PRCM12-2AO is an M12 connector-type inductive proximity sensor with a 2 mm sensing distance and AC 2-wire normally open output.
Ideal for AC control circuits where quick sensor replacement and maintenance are required.
The Autonics PRCM12-2AO is a connector-type inductive proximity sensor designed for detecting metal objects only in AC-powered control circuits. With an M12 threaded housing, 2 mm sensing distance (flush), and AC 2-wire normally open output, it enables direct switching of AC loads such as relays and contactors while allowing quick replacement using standard M12 connector cables.

FAQ
Q1. What does “PRCM” indicate in the model?
It indicates a connector-type (M12) proximity sensor.
Q2. Is this sensor suitable for PLC inputs?
No. This is an AC 2-wire sensor, not for DC PLC inputs.
Q3. What type of load can it switch?
AC loads such as relays, contactors, and pilot lamps.
Q4. What material can it detect?
Only metal objects.
Q5. What is the advantage of the connector type?
Allows quick replacement without rewiring, reducing downtime.
