D-A93 Applications

The D-A93 detects piston position in pneumatic cylinders via a magnet on the piston, mounting directly into the switch groove of compatible SMC actuators. As a 2-wire reed switch with a red LED, it suits relay and PLC inputs where a simple mechanical contact and 24 VDC/100 VAC compatibility are needed. Its wide load-current range (5 to 40 mA) and IP67 enclosure make it a robust, economical end-of-stroke sensor for general automation, air cylinders, and grippers.
