BNYZWOT MC-38 Mount NC Door Sensor Magnetic Reed Switch White 20pcs

Description

Product Overview

The BNYZWOT MC-38 is a surface‑mount, normally‑closed (NC) door sensor designed for reliable magnetic reed switching in demanding industrial environments. Constructed from a durable white ABS housing, the sensor offers a compact footprint of 27 × 14 × 7.8 mm, making it easy to integrate into tight panel spaces while maintaining a robust mechanical profile. The built‑in reed switch activates at an actuation distance of 18 mm ± 6 mm, providing a consistent response when the magnetic field is disrupted, which is essential for accurate door‑open detection.

Electrical specifications include a working voltage range of DC 0‑100 V, a maximum current of 0.5 A, and a power rating of 10 W, ensuring the sensor can handle typical control circuit loads without overheating. The 26 cm (10.24 in) 1007UL#24AWG wire offers sufficient reach for routing to PLCs, microcontrollers, or alarm panels, while the 4 mm mounting hole diameter simplifies PCB or panel mounting. The sensor’s low profile and white color blend seamlessly with most industrial panel aesthetics, reducing visual clutter and supporting standardized color‑coding schemes.

Designed for ease of installation, the MC-38 features a straightforward surface‑mount design that aligns with standard PCB manufacturing processes. The sensor’s leads are pre‑tinned, allowing for quick soldering, and the component’s footprint matches common industry footprints, minimizing the need for custom board layouts. Additionally, the sensor complies with RoHS standards, reflecting BNYZWOT’s commitment to environmentally responsible manufacturing practices.

Beyond its core technical attributes, the MC-38 benefits from rigorous quality testing, including temperature cycling, vibration, and electromagnetic interference (EMI) assessments. These tests verify that the sensor maintains performance across a wide temperature range and under mechanical stress, ensuring long‑term reliability in applications such as factory automation, security enclosures, and HVAC system monitoring. The product’s packaging includes 20 individual sensors, each accompanied by essential installation hardware, providing a complete solution for batch deployments.

Usage

The MC-38 NC door sensor excels in a variety of industrial scenarios where precise door status monitoring is critical. In manufacturing facilities, the sensor can be mounted on equipment cabinets to trigger alarms or shut down machinery when a door is opened unexpectedly, protecting both personnel and sensitive equipment. Its magnetic reed technology is also ideal for security enclosures, where it can interface with intrusion detection systems to provide real‑time alerts to security personnel.

Environmental robustness makes the MC-38 suitable for harsh conditions, including dusty, humid, or temperature‑fluctuating environments. The ABS housing resists corrosion and chemical exposure, while the sensor’s electrical characteristics remain stable across a broad voltage range, allowing it to be used in both low‑voltage control circuits and higher‑voltage monitoring applications. This versatility supports deployment in sectors such as automotive assembly lines, pharmaceutical clean rooms, and energy production facilities.

Integration with modern control architectures is straightforward. The sensor’s NC output can be directly connected to programmable logic controllers (PLCs), microcontroller inputs, or alarm panels without the need for additional signal conditioning. Its 26 cm lead length provides flexibility in routing, enabling designers to place the sensor in optimal locations while keeping wiring tidy and organized. The sensor’s low power consumption also contributes to overall system efficiency, an important consideration for large‑scale installations.

FAQ

What is the recommended mounting method for the MC-38 sensor?

The MC-38 is designed for surface‑mount installation on printed circuit boards or metal panels. Use the 4 mm mounting hole to secure the sensor with screws or rivets, and solder the pre‑tinned leads to the board for a reliable electrical connection.

Can the sensor operate in high‑temperature environments?

Yes, the sensor is rated for operation up to 85 °C (185 °F). The ABS housing and internal components have been tested for temperature stability, making the MC-38 suitable for applications such as furnace monitoring or outdoor enclosures when combined with appropriate thermal management.

Is the sensor compatible with both AC and DC power supplies?

The MC-38 works with a DC voltage range of 0‑100 V. While it is primarily intended for DC applications, it can be used with AC supplies if a rectifier or appropriate conditioning circuit is employed to convert the AC to a suitable DC level.

How many sensors are included in the package and what additional hardware is provided?

Each package contains 20 MC-38 sensors, each with a 26 cm 1007UL#24AWG wire. The kit also includes mounting screws and a small set of installation instructions to facilitate quick deployment in batch projects.
