MC-31 Surface Mount Wired NC Door Contact Sensor White 10pcs BNYZWOT

Description

Product Overview

The MC-31 surface-mount NC door contact sensor is engineered for reliable magnetic reed switching in demanding industrial environments. Constructed from durable white PVC, the sensor features a compact footprint with a 5.8 mm mounting hole, making it easy to integrate into panels, enclosures, and control cabinets. Its normally‑closed (NC) configuration ensures that the circuit remains closed until the magnet moves beyond the specified actuation distance, providing a clear and predictable signal for safety and monitoring applications. The sensor is supplied in a convenient 10‑piece pack, allowing for quick deployment across multiple doors or panels.

Usage

Designed for a wide range of industrial uses, the MC-31 sensor is ideal for monitoring door status on machinery, safety interlocks, HVAC systems, and automated equipment. Its 18 mm ±8 mm actuation distance accommodates various magnet strengths, ensuring reliable operation whether the door is opened slowly or quickly. The sensor’s surface‑mount design fits seamlessly onto printed circuit boards (PCBs) or directly onto metal panels, reducing wiring complexity and saving valuable space. It is particularly suited for applications where a quick, dependable indication of door open or close is critical, such as in production lines, warehouse doors, and secure enclosures.

FAQ

What does NC (Normally Closed) mean for this sensor?

NC indicates that the sensor’s contacts are closed when the magnet is within the actuation range, keeping the circuit active. When the door opens and the magnet moves beyond the set distance, the contacts open, signaling a change in state.

Can the MC-31 be mounted on a metal panel?

Yes, the surface‑mount design allows direct attachment to metal panels or PCBs using the 5.8 mm mounting hole, simplifying installation without additional brackets.

What is the recommended magnet type for optimal performance?

Any standard neodymium magnet with a pull force compatible with an 18 mm actuation distance works well. Ensure the magnet is positioned directly opposite the sensor for consistent operation.

Is the sensor suitable for high‑temperature environments?

The PVC housing is rated for typical industrial temperature ranges up to 70 °C (158 °F). For applications exceeding this range, consider a sensor with a specialized high‑temperature housing.
