It accepts process connections via a 1\/2 inch NPTF female thread and houses a dual SPDT contact arrangement. The adjustable setpoint range spans 20 psi to 500 psi on rise and 20 psi to 500 psi on fall, with a deadband adjustable between 4 psi and 30 psi. Wetted parts are constructed from 316 stainless steel, making the switch suitable for corrosive media. Electrical termination is handled through two 3\/4 inch NPT entry terminal blocks. The switch weighs 4 pounds.\u003c\/p\u003e\n\u003cp\u003eThis switch is intended for use in classified hazardous locations where flammable gases, vapors, or combustible dusts may be present. Typical installations include oil and gas facilities, chemical processing plants, industrial HVAC systems, and marine or petrochemical environments requiring certified explosion-proof equipment. Licensed electricians and instrumentation technicians are the primary installers. The J120-193 supports a wide voltage range covering 125, 250, and 480 volts AC as well as 30, 48, and 125 volts DC, making it adaptable to a broad set of control circuit configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExplosion-proof housing rated to multiple international standards including ATEX Directive 2014\/34\/EU, CSA C22.2, CQST, and CNEx certifications\u003c\/li\u003e\n  \u003cli\u003eAdjustable setpoint range from 20 psi to 500 psi on both rise and fall\u003c\/li\u003e\n  \u003cli\u003eAdjustable deadband from 4 psi to 30 psi for flexible process control\u003c\/li\u003e\n  \u003cli\u003e316 stainless steel wetted material for compatibility with corrosive process media\u003c\/li\u003e\n  \u003cli\u003eDual SPDT contact form supports two independent switching circuits from a single device\u003c\/li\u003e\n  \u003cli\u003eWide multi-voltage compatibility: 125, 250, 480 volts AC and 30, 48, 125 volts DC\u003c\/li\u003e\n  \u003cli\u003eMaximum pressure rating of 1500 psi provides substantial overpressure protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style explosion-proof pressure switch for hazardous-location control systems requiring a 1\/2 inch NPTF female process connection and dual SPDT output contacts.
