The 017D001466 pressure switch is manufactured by Danfoss in the RT Pressure Switches series for hydraulic automation circuits that need straightforward pressure-activated electrical signaling. It carries an SPDT contact arrangement so one common terminal can be switched between normally open and normally closed paths as pressure varies. The adjustable setpoint range extends from 0.5 bar to 4 bar to cover low-pressure lubrication alerts or pump start commands, and a fixed 0.3 bar contact differential limits rapid cycling when pressure fluctuates around the trip level. Once pressure falls below the reset value the mechanism returns automatically, eliminating manual resets. Reliable operation is maintained in ambient temperatures from −40 °C up to 70 °C, which supports outdoor equipment exposed to seasonal extremes.
An IP66 enclosure protects the switch against dust ingress and high-pressure water jets, allowing installation on machinery that requires regular wash-down. Two Pg 13.5 conduit entries provide separate routes for control and power conductors, while a 12 mm × 1.5 pressure port mates with common metric tube fittings used in hydraulic manifolds. The device endures continuous service at 22 bar working pressure and survives proof tests to 25 bar without mechanical damage, giving safety margin for transient spikes. Internal insulation accommodates circuits up to 400 V, and the relay can absorb impulse voltages of 4 kV, enabling direct connection to industrial relay coils or PLC inputs without additional surge suppression.
