Description
Description
The Miller Edge PS20A pneumatic switch offers a reliable, cost-effective alternative to an electric sensing edge, ideal for extremely wet, refrigerated doors subject to condensation, and low temperature climates. The PS20A switch enclosure accepts an air hose connection. When the hose is compressed, air is forced into the diaphragm and the switch is activated. This converts the pressure wave into an electrical contact, which signals the commercial door operator to stop and/or reverse motion. Pneumatic switches are compatible with pneumatic configured sensing edges and treadles, and are non-monitored.
Applications
- Pneumatic configured sensing edges on motorized doors
- Pneumatic configured treadles
- Signaling hoses on floors
Features
- Built-in strain relief
- Normally open or normally closed operation
- Easy to install
- Non-monitored
- 2-year warranty
