D-M9P SMC Solid State Auto Switch | 3-Wire PNP Sensor

The SMC D-M9P solid state auto switch is built for dependable position sensing on compatible SMC pneumatic actuators. As part of SMC’s general-purpose solid state auto switch family, the D-M9P is a direct mount, horizontal style switch with a 3-wire PNP output, making it a strong choice for applications that require accurate cylinder or actuator position feedback.

 

Designed for use in automated machinery, pneumatic workholding, pick-and-place systems, and general motion control applications, the D-M9P helps machine builders and maintenance teams confirm actuator movement and improve control system visibility. Solid state switching provides a non-contact sensing solution that supports repeatable operation in production environments where reliable feedback is critical.

 

SMC’s general-purpose solid state auto switch family includes multiple mounting styles, including band, rail, tie-rod, and direct mount options, along with electrical entry options such as grommet, connector, and terminal conduit styles. The D-M9P falls within the direct mount group and is identified as a solid state, general-purpose, 3-wire PNP, horizontal auto switch.

 

For manufacturers, OEMs, integrators, and maintenance teams, the SMC D-M9P is a practical solution for monitoring pneumatic actuator position, supporting machine sequencing, and helping reduce downtime during troubleshooting.
