The compact PE5 electronic pressure and vacuum switch is easy to operate and install, with three ergonomically-arranged buttons and numerous pneumatic connection options. The fully IP65-protected switch features a large, four-digit LCD display that is easy to read, and the pressure units shown can be tailored to suit the environment. The switches are available in two electrical versions, either with two digital switch outputs, or with one digital switch output and one analogue output. Versions with PNP or NPN outputs are available. The analogue output signal can be switched between voltage (0 - 10V) and current (4 - 20mA).It measures the relative pressure via a piezoresistive pressure sensor and has pressure range options from -1 to 10 bar (-14.5 to 145 psi). The pressure is shown on the illuminated LCD display in bright, large characters. Suitable for a wide variety of applications, the pressure units can be displayed as psi, inHG, bar and KPa.
