Safety Warning

Item Information

Parker's robust electro-hydraulic pressure switches series PSB ensure great flexibility for mounting with manifolds, sandwich plates or direct line connections. A hydraulically dampened piston provides accurate response and extended service life. The maximum operating pressure for all varations is 315 bar.

Markets:
• Industrial

Features/Benefits:
• Robust cast iron construction. Rugged, yet compact product - designed to provide long service life in demanding applications
• Four separate adjustable pressure range options - enables the operator to precisely select the desired pressure setting
• Flange or pipe mounting - therefore almost universally applicable
• Optional keylock adjustment - prevents tampering or unauthorized adjustments in critical applications
• IP65 class electrical protection - maintains integrity against moisture in spray or splashdown situations
• Short delivery time for most variations - no warehousing necessary

Applications:
• Suitable for general hydraulic applications

Function:
The spring loaded piston is hydraulically dampened. The PSB provides a very accurate hysteresis between the switching points. The required operating pressure is adjusted by the setscrew. Unauthorised adjustments can be prevented by the optional cylinder lock. The electric element is a micro switch with snap-action contact. Three terminals permit application as "On", "Off" or "Changeover" switch. The electrical connection is made with a 3-pole plug-in connector to EN 175301-803 with ground.

Note:
For inductive DC loads a spark discharger should be used to increase service life.
