Bosch Rexroth offers pressure/vacuum switch

Bosch Rexroth has unveiled the compact PE5 electronic pressure and vacuum switch with three ergonomically arranged buttons and numerous pneumatic connection options.

The IP65-protected switch features a large, four-digit LCD display, and the pressure units shown can be tailored to suit the environment.

It is available with two digital switch outputs or one digital 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).

The PE5 measures the relative pressure via a piezoresistive pressure sensor and has pressure range options from -1 to 10 bar.

The pressure is shown on the illuminated LCD display in bright, large characters (0.43in high), which change colour for rapid fault detection.

Suitable for a wide variety of industrial applications, the pressure units can be displayed as lb/in2, inHg, bar and kPa.

It can also be used as an analogue transducer.

With compact exterior dimensions of 1.4in W x 2.6in H x 1.3in D the PE5 can be mounted using an optionally available bracket or on a DIN rail.

To reduce downtime and maintenance costs, it can be combined with Rexroth's AS and NL Series maintenance units via a double nipple.

Depending on the version, the pneumatics connection is established either with a 4mm push-in fitting or a G1/4in internal thread on the underside.

A female G1/4 thread is available on the reverse of all versions for connection to regulators and distributor blocks.

The electrical connection is established with a four-pin M12x1 plug.

Options, including the displayed unit of pressure, switching modes, and others can be programmed using the three large push buttons.

After the switch has been programmed, it returns to display mode and shows the current pressure.

The unit of the displayed pressure can be seen in the lower section of the display and the switch output states are shown at the top.
