SOR 12RL-K5-J6-J1A Pressure Switch

The SOR 12RL‑K5‑J6‑J1A is a weatherproof pressure switch from SOR Controls Group designed for reliable low‑pressure control in air systems and light process applications. It actuates in the 0.75–12 psi range, with an adjustable set point read on a calibrated scale to precisely tailor the trigger point for your equipment. Inside, a force‑balanced, piston‑actuated sensing assembly drives a diaphragm‑sealed element and a static O‑ring, delivering robust response in demanding environments. The weatherproof housing protects wetted parts and electrical connections from dust and moisture, making it suitable for air, oil‑free service, and non‑corrosive process services that require a compact mechanical switch. Typical uses include compressor protection, low‑pressure alarms, and general process control where a defined pressure trigger is needed. This model is part of the broader SOR weatherproof family, which offers wide adjustable ranges and configurable wetted parts, along with common certifications such as CE, CSA, and SIL2, and a 3‑year warranty in many catalog offerings. Designed for straightforward field installation, the 12RL variant follows the standard mounting and calibration practices used across SOR’s weatherproof switches, delivering dependable actuation at precise low pressures.
