Adjustment range:

0.2 ... 400 bar


Mechanical pressure switch with a diaphragm or a piston sensing element and a change over contact for converting pressure into an electrical switching signal. An adjusting screw allows setpoints to be easily adjusted, even in situ. Optionally the setpoint may be factory preadjusted. The integrated micro switch allows switching capacities from 5 mA to 4 A.

The switch is suitable for non-aggressive or self-lubricating fluids, other media on request. It is available as standard with a ¼" thread zinc plated steel process connection. The switch is provided with flat connectors 3 x 6,3 x 0,8 as standard.

Many other threads and materials, including stainless steel, are optionally available. A protection cap made of NBR can be ordered as an accessory (AZM90X101007).

The S4150 is used for controlling and monitoring of liquids in machine and plant engineering, for pneumatic, hydraulic and mobile hydraulic systems and for example in plastic injection molding machines.
