Series DMF

Product catalog summary

Overview: The document provides technical specifications and features of the DMF Series mechanical pressure switches by Inelta Sensorsysteme GmbH & Co. These switches are designed for industrial applications, offering robust construction at a low cost.

Specifications:

Pressure Range: Adjustable from 0.1 to 50 bar.
Tolerance: Varies from ±0.1 to ±3.0 bar depending on the pressure range.
Overpressure Resistance: Up to 300 bar.
Switched Voltage: Up to 48 VDC.
Max Switched Current: 0.5 A for resistive load, 0.2 A for inductive load.
Mechanical Lifetime: Up to 10 million cycles.
Temperature Range: Ambient: -30 to 100°C, Medium: -20 to 100°C.
Protection Degree: IP00 without rubber cover, IP54 with rubber cover.

Features:

Robust and low-cost design with a steel housing.
Capsulated construction with various adjustable pressure ranges and fittings.
Available contact types: normally open or normally closed.
Flat connector size: 6.3 x 0.8 mm.

Applications: Suitable for industrial applications, engine and installation construction, and industrial presses.

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 such as air, hydraulic oil, and sea water, with temperature resistance up to 120°C.

Ordering Information: The order code specifies series, housing material, contact type, membrane material, pressure fitting, and pressure range.
