SOR, Inc. 6NN-K3-M4-C2A-TT Pressure Switch

The SOR 6NN-K3-M4-C2A-TT Pressure Switch is a 12–100 psi adjustable switch with a 3/4" NPT(F) right-hand pressure port, housed in a rugged aluminum enclosure rated NEMA 4, 4X and IP66 for reliable service in dirty or wet industrial environments. The switch employs a 6-3 piston-spring design and uses Viton O-rings with a 316L stainless steel diaphragm (M4 wetted parts), and it provides AC operation up to 250 V at 15 A and DC resistive up to 125 V at 0.4 A; it tolerates overpressures up to 1500 psi and a proof pressure of 2500 psi. With a typical dead band of 0.9 psi and a dead-band multiplier of 1.0 for SPDT or 6.0 for DPDT configurations, the unit weighs about 3 kg and is designed for automatic switching in hydraulic and pneumatic systems.
