The 060B016866 model is produced by Danfoss for the MP Differential Pressure Switches series. It monitors pressure differences in hydraulic automation circuits and triggers control contacts when thresholds are reached. The device uses an SPDT contact arrangement, allowing a single common conductor to switch between two outputs for start or stop commands. A Pg 13.5 cable entry supports standard wiring glands. Housing protection is rated IP20 so installation should be inside a clean cabinet. Mechanical hookup is through a 1/4-inch flare pressure connection compatible with refrigeration or hydraulic lines. The switch functions in ambient temperatures from −40 °C to 60 °C, making it suitable for cold storage or warm plant rooms.
Pressure behavior is defined by a fixed differential of 0.65 bar combined with a contact differential of 0.2 bar to create a stable switching band. The low-pressure port tolerates values from −1 bar to 12 bar, while the assembly endures a continuous working pressure of 17 bar and a test pressure of 22 bar for brief verification procedures. Electrical insulation withstands impulse voltages up to 4 kV. Once actuated, the relay releases after 90 s, a delay that prevents rapid cycling. A manual minimum reset function requires user intervention once pressure falls below the chosen limit, guaranteeing controlled restart of the connected hydraulic equipment.
