PSW-A6

Can sense the difference between two pressure levels as well as positive and negative pressure.

Switching point: Pressure: 5 - 800 mbar Vacuum: 10 - 800 mbar

Contact arrangement: Single pole, single throw, normally open or normally closed (SPST N.O. or N.C.)

Upper port can be delivered with a different orientation than the lower port

This pressure switch is usually used to sense differences between two pressure levels, but can also be used to sense pressure or vacuum. The switch is optimised for use on circuitboards, therefore the electrical contacts are two 1.0 mm pins. Furthermore the upper part of the pressure switch can be delivered with a different orientation of the upper pressure port compared to the lower port. The low tolerance of ±5% in a wide range and low hysteresis are also features of this switch. The switching point can be changed by the user with a adjusting screw. The switch can be delivered as single pole single throw normally open or normally closed (SPST N.O. or N.C.) and with silver-alloy or gold-alloy contacts. A single model cannot cover the whole setpoint range, for a given setpoint, an appropriate spring is used.
