Plastic Reed Switch 5pcs with 10 Small Magnets WOWOONE N/O 2.5mm×14mm

Description

Product Overview

The WOWOONE 5‑piece reed switch kit is engineered with a precision‑molded glass envelope measuring 2.5 mm in diameter and 14 mm in length, providing a compact footprint that easily fits into tight panel spaces. Each reed switch features a high‑quality stainless‑steel reed that reacts instantly to magnetic fields, delivering a normally‑open (N/O) contact configuration that is ideal for a wide range of sensing and control applications. The included ten small round neodymium magnets are sized for multi‑use versatility, allowing users to experiment with magnetic positioning, polarity, and field strength to achieve optimal switching performance.

Designed for reliability, the switches support a maximum switching voltage of 100 VDC and a continuous current rating of 0.5 A, with a peak charging current capability of 1.0 A. The contact resistance is limited to 100 MΩ, while the insulation resistance exceeds 10¹⁰ Ω, ensuring stable operation even in harsh industrial environments. The sealed glass construction protects the internal reed from dust, moisture, and mechanical shock, extending the service life and reducing maintenance requirements.

Packaging includes five reed switches and ten magnets, neatly organized in a durable anti‑static bag that safeguards the components during shipping and storage. The product is certified under the ASIN B08K36VLZ2 and has earned a solid 4.1‑star rating from 87 verified customer reviews, reflecting consistent satisfaction with performance, ease of integration, and value for money. This kit is compatible with a broad spectrum of control panels, PLCs, and microcontroller boards, making it a flexible solution for engineers, hobbyists, and educators alike.

Usage

In industrial automation, the reed switches serve as reliable proximity sensors for detecting the presence or movement of ferromagnetic objects without physical contact. Their fast response time and low power consumption make them suitable for conveyor belt monitoring, robotic arm joint detection, and safety interlock systems where rapid actuation is critical. The included magnets can be mounted on moving parts or fixed positions to create custom magnetic fields that trigger the reed switch at precise moments.

For hobbyist and educational projects, the compact size and straightforward wiring of the switches enable quick prototyping of magnetic door sensors, DIY security alarms, and interactive art installations. The N/O configuration simplifies circuit design, allowing the switch to close a circuit only when a magnetic field is present, which is perfect for creating toggle mechanisms or counting rotations in a low‑cost, low‑maintenance manner.

Beyond traditional applications, the reed switches can be integrated into environmental monitoring systems, such as water level detectors where a floating magnet activates the switch at predefined thresholds. Their ability to operate without wear and tear makes them an excellent choice for long‑term deployments in outdoor or corrosive environments, especially when paired with appropriate sealing enclosures.

FAQ

What is the maximum distance a magnet can be from the reed switch and still activate it?

The activation distance depends on the magnet’s strength and the reed switch’s sensitivity. For the included small neodymium magnets, reliable activation typically occurs within 2–3 mm of the glass envelope, but stronger magnets can extend this range up to 5 mm.

Can the reed switches be used in high‑temperature environments?

Yes, the glass housing and stainless‑steel reeds are rated for continuous operation up to 85 °C (185 °F). For applications requiring higher temperatures, additional heat‑resistant enclosures are recommended.

Are the switches compatible with both DC and AC circuits?

The switches are specified for a maximum voltage of 100 VDC. While they can handle low‑frequency AC signals below this voltage, they are primarily intended for DC applications where the magnetic actuation is more predictable.

How do I replace a faulty reed switch in an existing circuit?

Because the switches are solder‑type, you can desolder the faulty unit and replace it with a new one from the kit. Ensure the replacement is oriented the same way, with the leads aligned to the original circuit layout.

Do the magnets interfere with other electronic components?

The small round magnets are low‑profile and typically do not cause electromagnetic interference with nearby circuitry. However, it is good practice to keep them at a reasonable distance from sensitive analog components or high‑frequency RF modules.
