DSY Wired Roller Shutter Garage Door Magnetic Switch Sensor MC-55

Description

Product Overview

The DSY MC-55 magnetic switch sensor is engineered specifically for metal roller shutter garage doors, providing a reliable method to detect door position and trigger alarm or automation systems. Constructed from a robust zinc alloy shell, the sensor resists corrosion, high temperatures, and mechanical wear, ensuring a long service life even in harsh industrial environments. Inside the housing, a high‑quality reed switch works in conjunction with a powerful neodymium magnet to create a contact‑free switching action that activates when the door is fully closed. The sensor includes a 38 cm (15 in) cable wrapped in stainless steel hose, offering excellent flexibility and protection against abrasion, oil, and moisture. Electrical specifications include a 0.5 A current rating, 100 V maximum voltage, and a power rating of 10 W, making it compatible with most low‑voltage control circuits. The action distance exceeds 50 mm, allowing flexible mounting options without precise alignment requirements.

Usage

This magnetic switch is ideal for a variety of commercial and industrial applications where secure door monitoring is essential. Typical installations include warehouse roller shutters, commercial garage doors, loading dock doors, and security‑controlled entryways. The sensor can be integrated into existing alarm systems, building automation platforms, or custom PLC logic to provide real‑time status updates and trigger alerts if a door is left open or forced. Its compact size and flexible cable make it easy to mount on the frame or jamb of the shutter, and the non‑contact operation eliminates wear points, reducing maintenance costs. The DSY MC‑55 is also suitable for use in harsh environments such as cold storage facilities, chemical plants, and outdoor installations where exposure to dust, moisture, and temperature fluctuations is common.

FAQ

What is the recommended mounting position for the sensor?

The sensor should be mounted on the door frame so that the magnet aligns with the reed switch when the door is fully closed. A clearance of at least 5 mm between the magnet and the switch ensures reliable activation.

Can the DSY MC‑55 be used with high‑voltage systems?

No. The sensor is rated for a maximum of 100 V and 0.5 A. For higher voltage applications, a suitable step‑down transformer or relay should be used.

Is the sensor compatible with wireless alarm systems?

Yes. The sensor provides a dry contact output that can be connected to wireless alarm modules or PLC inputs that accept low‑voltage signals.

How does the sensor handle extreme temperatures?

The zinc alloy housing and stainless steel cable are rated for temperatures up to 85 °C, making the sensor suitable for most indoor and outdoor industrial environments.

What warranty does DSY offer?

DSY provides a one‑year limited warranty covering manufacturing defects, along with access to technical support for installation and troubleshooting.
