The universal pressure switch DCMV10 is suitable for use in general mechanical engineering, the printing machine industry, as well as in pneumatics and hydraulics. This type covers a setting range of 1…10 bar and is designed for a maximum permissible pressure of 25 bar.

The switching differential can be adjusted externally for this type. The available range is 0.5…2.8 bar.

The DCM/DNM series is designed for overpressure monitoring in industrial applications. The devices have a robust design and can be adjusted externally using a screwdriver. Depending on the version, different materials are used for the pressure-wetted parts.

Technical data

• Pressure connection: External thread G 1/2 (pressure gauge connection) according to DIN 16 288 and internal thread G 1/4 according to ISO 228 Part 1.
• Switching device: Robust housing (200) made of seawater-resistant die-cast aluminium GD Al Si 12.
• Protection class: IP54 in vertical position.
• Pressure sensor materials: Type-dependent, see product summary in the datasheet.
• Mounting position: Vertically upright and horizontal. DCM4016 and DCM4025 vertically upright.
• Ambient temperature at switching device: -25…+70 °C; DCM4016, DCM4025 and DCM1000: -15…+60 °C.
• Max. medium temperature: The maximum medium temperature at the pressure sensor must not exceed the permitted ambient temperature at the switching device. Short-term temperatures up to 85 °C are possible. Higher medium temperatures are possible if the limit values at the switching device are ensured by suitable measures, for example a siphon.
• Mounting: Directly on the pressure line (pressure gauge connection) or on a flat surface with two 4 mm diameter screws.
• Switching pressure: Adjustable externally with a screwdriver.
• Switching differential: Not adjustable for DCM types. Adjustable externally for DCMV types. See product summary for values.
• Contact arrangement: Single-pole changeover switch.
• Switching capacity: See datasheet for the electrical switching capacity values.
