October 8, 2008 - The Rexroth PE5 electronic pressure and vacuum switches are available in two electrical versions: with two digital switch outputs or with one digital switch output and one analog output. Versions with PNP or NPN outputs are available. Its analog output signal can be switched between voltage (0 - 10 V) and current (4 - 20 mA). The PE5 electronic pressure switch is designed to measure the relative pressure via a piezoresistive pressure sensor and has pressure range options from -14.5 to 145 psi (-1 to 10 bar).
The pressure is shown on the illuminated LCD display in bright, large characters (0.43” in height).
Pressure units can be displayed as psi, inHG, bar and KPa.With compact exterior dimensions of 1.4”W x 2.6”H x 1.3”D, the PE5 electronic pressure switch can be mounted using an optionally available bracket or on a DIN rail.
Additionally, the PE5 switch can be combined with the Rexroth AS and NL series maintenance units via a double nipple. Depending on the version, the pneumatics connection is established either with a 4 mm push-in fitting or a G1/4” 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 4-pin M12x1 plug.The switches’ options, including the displayed unit of pressure, switching modes, and others can be programmed quickly and easily using the three large, user-friendly 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.Bosch Rexroth AG, part of the Bosch Group, achieved sales of approximately $7.4 billion (5.4 billion Euros) in 2007 with nearly 33,000 employees.
