NEMA 4 Exterior Pneumatic Air Switch – 2 Wire, Metal Enclosure

This exterior pneumatic air switch is designed for commercial garage door, industrial door, gate, and vehicle-activated signal hose systems. Air pressure created when the connected pneumatic or signal hose is compressed activates the switch, allowing the system to send a control signal to compatible door, gate, or access-control equipment.

The switch features a durable metal NEMA 4 enclosure designed for exterior installations and demanding commercial environments.

How It Works

A pneumatic signal hose is positioned where vehicle tires or other moving loads can compress it.

When the hose is compressed, a pulse of air travels through the hose to the air switch. The switch responds to that pressure change and sends an electrical control signal to the connected system.

This allows vehicles to activate compatible commercial doors, gates, warning devices, or other access-control equipment without placing electrical wiring inside the drive-over hose.

Compatibility

Designed for use with compatible pneumatic signal hose systems.

Verify the existing hose type, wiring configuration, operator controls, and required switch function before ordering.

Exterior Metal Enclosure

The metal NEMA 4 housing provides added protection for installations exposed to dust, moisture, and typical exterior commercial environments.
