Industrial 201NN-K125-RR Temperature Switch 40-225F

SOR’s 201NN-K125-RR Temperature Switch is a rugged, direct- or remote-mount device that pairs a sealed temperature-sensing element with a pressure switch body in the 201NN family, designed for reliable temperature-based control in harsh industrial environments where weatherproof, dependable switching is required. It provides SPDT Form C contacts and a 40 to 225°F (5 to 107°C) sensing range, with a switching capability up to 15 A, enabling control of motors, pumps, fans, or alarms in process systems; the unit is designed for direct mounting and can be deployed in weatherproof housings. The NN-K125 configurations are offered in weatherproof enclosures (NEMA 4/4X, IP65), and some variants are available in explosion-proof styles for hazardous locations, with a maximum process pressure rating around 2300 psi. In industrial settings, this switch serves as a compact, robust temperature monitoring and control device, enabling automatic shutoff or activation of equipment when the process temperature crosses the specified range.
