Product catalog summary
Overview: The document provides technical specifications and features of the DMM series mechanical pressure switches manufactured by Inelta Sensorsysteme GmbH & Co. KG. These switches are designed for industrial applications, including engine and installation construction and industrial presses.
Specifications:
  • Pressure Range: Adjustable from 0.1 to 50 bar.
  • Switching Voltage: Up to 48 VDC.
  • Mechanical Lifetime: Up to 10 million cycles.
  • Housing Material: Available in steel (SMNPB36) and brass (CuZn40 PB2).
  • Temperature Range: Ambient: -30 to 100°C; Medium: 80 to 120°C.
  • Protection Degree: IP00 without rubber cover, IP54 with rubber cover.
Features:
  • Robust and low-cost design.
  • Available in different pressure fittings and contact types (normally open or closed).
  • High load cycles capability.
Function Principle: The switch operates via a sealing membrane that actuates a plunger held by a spring. The switch pressure is determined by the adjustable spring tension, which triggers a mechanical contact.
Material Compatibility: The membrane is available in various materials (NBR, FKM, EPDM, Neoprene) suitable for different media, including alkaline, brake fluid, sea water, air, hydraulic oil, and more.
Ordering Information: The order code includes series, housing material, contact type, membrane material, pressure fitting, pressure range, and switching pressure options.

Serie DMM / Series DMM Druckschalter / Mechanical pressure switches Funktionsprinzip / Function principle Über eine Dichtungsmembran, verfügbar in verschiedenen Materialien, (siehe Verträglichkeitstabelle), wird ein Stößel, gehalten von einer Feder, betätigt. In Abhängigkeit der einstellbaren Federkraft kann der Schaltdruck bestimmt werden. Durch die Verformung der Feder löst der Stößel einen mechanischen Schaltkontakt aus. A sealing membrane operates a plunger, held by a spring. The mebrane is available in different materials (see table medium compatibility). In dependence of the adjustable...
