PS-7711-101 is a magnet-actuated reed switch type proximity sensor designed for general-purpose switching applications. It features a normally closed (NC) contact form with a maximum switching capacity of 10W at DC 100V and a maximum switching current of 0.25A. The sensor operates with a contact resistance of 0.3O or less and is housed in an ABS resin case with UL1007 AWG26 wire, providing a hollow design suitable for iron plate shielding applications. The device operates over a temperature range of 0°C to +60°C and can withstand vibration up to 294 m/s² with full amplitude of 1.52mm at frequencies between 10–55Hz, making it reliable for industrial automation, door/window monitoring, and proximity detection systems.
