Pressure switches open and close an electrical contact at a previously defined pressure. As soon as the pressure is reached, a further work step is started or stopped by an electrical signal. ■ Option of integration with the HAWE modular system ■ General hydraulic systems

Available versions Circuit symbol Ordering example Pressure setting (factory-set, optional), bar ■ Series: setting with increasing pressure ■ Coding F: setting with decreasing pressure Low-temperature seal configurable only with DG 35 -X. and DG 364 -X. Their micro switches are installed with gold contacts.

Switching operations Electrical connection Reference values approx. 2000/h max. (roughly equally distributed). Note the number of possible switching cycles; see below. Switching accuracy * 2 to 3 % (repeat accuracy for increasing pressure!) product assembly instructions

Maximum supply voltage < 50 V AC or 75 V DC Umax Switching current Imin To ensure a safe contact, the current must not fall below certain minimum values: When deactivating pumps directly, be aware of a potential afterrun caused by mass action. Also available for delivery with preset pressure. ■ DG 33-600 (setting for increasing pressure) ■ DG 33-600 F (setting for decreasing pressure) Pressure increases Pressure drops The tables only contain approximate reference values. Use a pressure gauge to establish a more accurate switching point! ■ DG 1 R..: Using a setting knob on the pressure selection...

Overloading components due to incorrect pressure settings. Risk of minor injury. ■ Pay attention to the maximum operating pressure of the pump, valves and fittings. ■ Always monitor the pressure gauge when setting and changing the pressure. Fine contamination can significantly impair the function of the product. Contamination can cause irreparable damage. Examples of fine contamination include: ■ Rubber particles from hoses and seals ■ Dirt due to assembly and maintenance ■ Chemical ageing of the hydraulic fluid New hydraulic fluid from the manufacturer may not have the required purity.
