Overview
The United Electric J6-S142B is a compact, field-proven pressure switch designed for critical alarm, safety, and emergency shutdown applications requiring high switch sensitivity. This industrial-grade unit combines robust construction with precise pressure control, making it a trusted choice for maintenance technicians and controls engineers across manufacturing, HVAC, compressor, and fluid power systems.
Key Features
- 1 SPDT Switch Output — single-pole, double-throw contact for flexible control logic integration
- Welded 316L Stainless Steel Bellows — exceptional corrosion resistance and durability in harsh environments
- 0–18 PSI Adjustable Setpoint Range — factory pre-set or field-adjustable to match application pressure thresholds
- 4″ to 7″ WC Deadband — tight differential control for precise switching accuracy
- 1/2″ NPTF Pressure Connection — standard industrial thread fitting for quick installation
- Simple Installation & Operation — gasketed die-cast aluminum housing, no special tools or training required
