Industrial D-C73C Reed Switch

SMC D-C73C Reed Auto Switch is a band‑mount, non‑contact sensing device that switches 5 to 40 mA at 24 VDC. This inline reed switch is designed for mounting on bands or curved surfaces, providing a compact sensing element that converts a magnetic field into a logic signal for PLC inputs or relay coils in industrial automation. Typical uses include end‑of‑travel or proximity sensing on conveyors and machinery where space is limited, as well as door or cover position sensing in automation enclosures. Some D-C73C variants include an LED indicator to show when the switch is energized, aiding diagnostics in control panels and maintenance procedures. As a reed auto switch, it offers a simple, magnetically actuated switching solution that integrates with common control circuitry for reliable machine sensing tasks.
