Membrane pressure switch targets HVAC, pneumatic and process applications

Available in a choice of brass (EPS01) or stainless steel (EPS02) housings, these competitively priced switches offer generous overpressure limits and a choice of NBR or Viton® diaphragm materials for maximum application flexibility.

The new EPS01 and EPS02 series pressure switches feature a G 1/8 pressure port as standard with other fastening thread options available for larger quantities. Designed for any mounting orientation, versions are available for single pole operation with NC or NO contacts in pressure ranges of 0.3 to 2 bar and 1 to 10 bar. The integrated micro switch is available with silver plated contacts as standard for the EPS01, and with silver or gold plated switches optionally available for the EPS02.

The media temperature range of -25 to +85 °C and a switch point accuracy of under 10% will suit a wide range of switching tasks whilst a mechanical life of over 1 million cycles and a switching frequency of 200/min helps to ensure more than satisfactory performance requirements.

Both models also feature a maximum switching load of 2.0 A (resistive), a 100 VA breaking capacity and reference voltage of 42 V. Electrical connection is via flat 6.3 mm terminals. The slightly smaller, brass-housed EPS01 has a 17 mm AF hexagonal fixing whilst the stainless steel EPS02 model has 19 mm AF fixing.

The EPS01 and EPS02 are part of a universal family of pressure switches from Variohm EuroSensor. A third range, the EPS03, covers spring-loaded diaphragm or piston actuation with a micro switch switching element in a tough galvanised steel housing for pressure switching up to 350 bar.
