## **DESCRIPTION** 

The PBN1 series is available in a wide range of actuation pressures. The required pressure can be supplied factory set or as an adjustable unit. Smooth 4 mm diameter ports perpendicular to the housing and 5 mm barbed radial ports are available. Nominal actuation pressure varies from 1 in-H2O to 50 in-H2O on factory set models. Adjustable models have actuation pressures which can be set up to 416 in-H2O.

## **PHYSICAL SPECIFICATIONS** 

## **DESCRIPTION** 

The PBN3 series is a range of miniature, high-current, lowpressure devices which measure gauge pressure and can switch up to 16(4) A. Smooth 4 mm perpendicular ports and 5 mm barbed radial ports are available. Nominal actuation pressure varies from 1 in-H2O to 6,5 in-H2O. Adjustable models have actuation pressures which can be set from 10 in-H2O to 1109 in-H2O. 

PBN3 devices comprise a snap-action SPDT pressure switch which contains an actuator assembly and miniature micro switch. The devices are designed to respond to positive air pressure but may also be activated by non-corrosive liquids at low pressures.
