Overview
The SMC D-H7PW is a solid state auto switch with integrated 2-color LED indication for precise actuator position monitoring in pneumatic systems. This D-H7PW unit operates across DC5–24V supply voltages and features PNP output logic, making it suitable for direct integration with industrial controllers, PLCs, and relays. The dual-color indicator provides real-time feedback: red LED indicates out-of-range detection, green LED indicates optimum operating position.
