Description
Product Overview
The MEI Magnetic Reed Switch (model LE007) is engineered to provide precise, dependable magnetic sensing for a wide range of security and automation applications. Featuring a compact recessed form factor measuring 23.2 mm × 22.8 mm × 22.6 mm, the switch can be seamlessly integrated into door frames, window sashes, and panel housings without protruding into the operating space. The device offers both Normally Closed (NC) and Normally Open (NO) contacts, allowing installers to select the most appropriate logic for their system. Rated for up to 100 V and a maximum contact current of 500 mA, the switch delivers a reliable 10 W power handling capability, ensuring consistent performance even under fluctuating load conditions. Constructed from high‑grade stainless steel reeds and a durable polymer housing, the switch resists corrosion, mechanical wear, and environmental contaminants, making it suitable for indoor residential use as well as semi‑outdoor installations where exposure to humidity and temperature variations is common. The package includes five individual switches, each pre‑wired with a 34 cm (13.4 in) lead set—gray for NC, red for NO, and white for common—providing a clear, color‑coded wiring scheme that reduces installation errors and speeds up deployment. With a proven track record reflected in a 4.4‑star rating from ten verified customers, the MEI reed switch has earned a reputation for reliability, ease of use, and value in the industrial and scientific market segment.
Usage
Designed for home security, the MEI Magnetic Reed Switch excels in applications such as door and window alarm sensors, where a quick and accurate response to opening events is critical. Install the switch in a recessed cavity of a wooden or metal door, aligning the magnetic counterpart on the moving panel to maintain a trigger gap of 15‑25 mm for optimal activation. When the magnetic field is disrupted, the NC contact opens (or the NO contact closes), sending a signal to a control panel, alarm siren, or smart home hub. Beyond residential security, the switch is well‑suited for low‑voltage LED lighting control, relay activation in HVAC systems, and GPS‑based low‑power devices that require a compact, low‑current sensor. Its 5‑pack configuration enables multi‑point monitoring across a property, allowing users to protect multiple entry points with a single purchase. The straightforward wiring—gray for NC, red for NO, and white for common—facilitates integration with existing alarm circuits, microcontroller inputs, or PLC modules, making the switch a versatile component for hobbyists, professional installers, and system integrators alike.

FAQ
What is the recommended installation gap for the magnetic counterpart?
The optimal trigger distance is between 15 mm and 25 mm. Maintaining this gap ensures reliable activation while minimizing false alarms caused by minor vibrations or magnetic interference.
Can the switch be used with a battery‑powered alarm system?
Yes. The switch’s low current draw (maximum 500 mA) makes it suitable for battery‑operated panels and wireless alarm modules, extending battery life while delivering consistent performance.
Is the switch compatible with smart home hubs such as Zigbee or Z‑Wave controllers?
Absolutely. The switch’s simple dry‑contact output can be interfaced with most smart home gateways that accept binary inputs, allowing you to integrate door/window status into automation routines and mobile notifications.
How does the MEI switch compare to other reed switches in terms of durability?
MEI’s stainless‑steel reed and sealed polymer housing provide superior resistance to corrosion, humidity, and mechanical wear, resulting in a longer operational lifespan compared to standard carbon‑based or unsealed reed switches.
What warranty and after‑sales support are offered?
Each purchase includes a 90‑day money‑back guarantee. Our dedicated support team is available to answer technical questions, provide installation assistance, and address any concerns you may have after the sale.
