Overview
The SMC D-H7PW is a solid state auto switch designed for pneumatic automation systems. This band-mounted switch provides non-contact magnetic sensing for cylinder position detection. The D-H7PW features 2-color indication output (green/red) for clear visual status confirmation and operates as a PNP-type sensor on 5–24 VDC supply.
Key Features
- Solid state (non-contact) design eliminates mechanical wear and improves durability
- 2-color LED indication for ON/OFF status visibility
- Band mounting style for easy installation on pneumatic cylinders
- PNP 3-wire output for direct logic controller integration
- IP67 enclosure rating for protection in industrial environments
- Available with diagnostic output and magnetic field resistant configuration options
