Product Description
The Hydac 306849 VM5C.0 is an electrical switch dirt alarm indicator designed to alert operators when hydraulic filter elements near capacity. This clogging indicator measures the pressure differential across the filter element and automatically resets when pressure drops below trip pressure, providing early warning protection for hydraulic circuits.
- Switch Type: N/C or N/O change-over contacts
- Connection Size: G 1/2
- Maximum Operating Pressure: 3000 psi (210 bar)
- Operating Temperature Range: -30 to 100°C (-22 to 212°F)
- Pressure Setting: 5 bar (72 psi)
- Maximum Current Load: 5 A
- Housing Material: Aluminum
- Electrical Connection: Male M20 with female connector to DIN 43650
- Degree of Protection: IP 65 (when connector is wired and fitted correctly)
- Tightening Torque: 33 N·m (24 lb·ft)
This differential pressure indicator reacts to the pressure drop across the filter caused by fluid flow and element clogging. Suitable for applications requiring measurement of pressure differential upstream and downstream of filter elements. The single-pole, double-throw switch provides normally open or normally closed contact options based on site wiring configuration. Magnetic coupling design eliminates dynamic seals and reduces fluid leakage risk under high system pressure.
