ANVER Pneumatic Vacuum Switch

The JTSPO/C Pneumatic Vacuum Switch is a three way piloted switch with an adjustable vacuum pilot setpoint. The adjustable pilot can be set to sense vacuum up to 29.9″ Hg. Available in both Normally Open and Normally Closed models, the switch can be used in energy saver applications where low differential and fast response are required.

Maximum Vacuum: 29.9 in. Hg
Mounting: 1/8 in. NPT
Sensing Range: -3.5 to 28 in. Hg
Signal Pressure: 100 PSI Maximum
