Sourced and supplied by Al Imran Enterprises, Lahore, Pakistan. The Fuji Electric PM-2M is a magnetically operated reed proximity switch from the PM series standard type — the quiet workhorse behind countless door, gate and flap position detections in industry. Its principle could not be simpler: a sealed reed contact closes when the associated PM31 permanent-magnet element comes near, and opens again when it moves away. Because the switch is entirely passive, it needs no supply wiring, emits no leakage current and keeps working through power interruptions — qualities that make reed switches the default choice for door open/close sensing on machine guards, elevator and lift doors, conveyor end positions and level flaps. The breaking capacity is 0.5 A at 220 V AC on a single NO reed contact, ample for PLC inputs, pilot relays and indication lamps, and the resin-molded body is water-tight, dust-tight and shock-resistant, shrugging off washdown splashes, airborne fibre and the vibration of nearby gearboxes. Colour-coded lead wires of one metre length arrive ready for direct termination into panel marshalling. The pairing matters: PM series switches are calibrated to work with their matching PM series magnetic elements, and the combination is frequently marked PM-2M | PM31 on supplier listings, reflecting how the two ship together in practice — the switch body plus the PM31 magnet that triggers it. In Pakistani plants these sensors sequence textile machinery, watch machine guards on packaging lines, and report gate positions in process skids, usually unnoticed until a broken one stops a whole interlock chain.
