Catalog excerpts

Hydraulic accessories Pressure switch type DG, electronic pressure transducer type DT Pressure switches are hydraulic accessories. They close or open electrical contacts when under pressure. They are used to issue an electrical switching command or signal for further work steps when a predened pressure value is reached. Two independent switching points can be programmed. Pushbuttons or IO-Link can be used to carry out the setting. Features and benets: ■ Two switch outputs as normally closed contact or normally open contact, PNP or NPN programmable ■ System pressure is constantly measured and shown on the display ■ Optical switching point monitoring by LED ■ IO-Link communication ■ Compact design ■ Option of integration into the HAWE modular system ■ Operating pressures up to 1000 bar Nomenclature: Spring-loaded piston-type pressure switch Electronic pressure switch Electronic pressure transducer Intended applications: ■ General hydraulic systems ■ Machine tools Screw-in version Manifold mounting Designed for pipe connection Design and order coding example DG 51 E Hydraulic connection Basic type Table 2 Pressure stages Table 1 Hydraulic connection Pressure switch type DG ■ ■ ■ Type DG 1, 3 (spring-loaded piston-type pressure switch) Type DG 51, DG 6 (electrical pressure switch with two switch points) Type DT (analogue electronic pressure transducer)
