Pneumatic Timers for door access

750 Series Door Access Pneumatic Timers Precise and rugged pneumatic miniature timers.

Highpower Security 750 Pneumatic Timers are miniature momentary time delay switches for OEM applications. Pressing the switch button, or push plate (when used in an assembly) actuates the switch’s contacts. These contacts stay actuated for a set time delay, which is adjusted using the brass knob at the back of the switch. Turning the brass knob controls an internal flow of air that regulates the time delay.

These pneumatic timer units are used in many switch assemblies for security and industrial control applications. Close manufacturing tolerances, hand-built attention to detail and all-metal construction provides improved, more repeatable precision timing cycles and long life performance.

Our 750-4000 Model is a miniature pneumatic timer, often used for applications where smaller space is a factor. 750 timers feature “Form Z” switch contacts (one pole “normally open” and a second separated pole for “normally closed”).  750-1000 pneumatic timer and 750-4000 pneumatic timer models are furnished with wires. 750-2000 and 750-4100 pneumatc timers are furnished with terminal blocks. Made in U.S.A.
