52 Series Pneumatic Timer

The Set and Forget 52 series pneumatic timers are ideal for applications where the time preset is set once and rarely adjusted; they are configured as ON delay or OFF delay timing with connections to the side or the underside of the device.

The 52.SB series pneumatic timer directly replaces Kuhnke pneumatic timers 51.006.00, 51.006.01, 51.012.00, 51.012.01 and 51.018.00.

Timing options are 0.5 to 60 seconds, 1 to 120 seconds or 3 to 180 seconds.

Based on a reservoir and diaphragm design, there are few moving parts, no process display, and the time remaining to output is not visible. It is a rugged product with excellent repeatability and suited to many arduous applications that demand continued reliability.

On applying pressure to the timing control port, the timing sequence begins. On completion of the time preset, the valve provides ON delay or OFF delay timing. The timing mechanism and valve automatically reset after removing pressure from the timing control signal port.

Set and Forget pneumatic timers can be base mounted, or by using the two M3 female threaded inserts on the top cover of the timer, they can be installed onto a panel.

When used within its design parameters, this product does not have the potential for ignition; therefore, it can be used within an ATEX environment, product group IIG/IID, category 3, zones 2 & 22, not downhole mining applications, which require full independent certification.
