World Magnetics PSF100A NSNBC01 Pressure Switch

The World Magnetics PSF100A NSNBC01 Pressure Switch is an industrial ultra-sensitive low-pressure sensing device in the PSF100A DesignFlex Series, built for precise pressure, vacuum, and differential pressure monitoring and switching. It uses an SPST normally open, double‑make/double‑break contact and supports a configurable pressure range from 0.1" to 50" H2O (depending on configuration) with a proof pressure of 8–15 psi and more than 20 million mechanical cycles, plus MIL-SPEC shock and vibration resistance for demanding environments. The switch is designed for air and compatible fluids on the high side, with dual.200" barbed ports for 1/8"–3/16" ID tubing,.187" x.020" tab terminals, and a polycarbonate housing housing a polyurethane diaphragm (Teflon optional) and dual gold contact points, weighing less than 10 grams. Commonly used in HVAC airflow systems, air handling equipment, clean rooms, pneumatic automation, dust collection, and industrial sensing where reliable low‑pressure detection and automated pressure control are required.
