2205A-L SENTROL Miniature Mount Overhead Door Magneticcontact

Review SENTROL Miniature Heavy Duty Surface Mount Overhead Door Magneticcontact

Introducing the Sentrol 2205A-L Miniature Mount Overhead Door Magnetic Contact, a versatile and reliable solution for monitoring the opening and closing of your overhead doors. This magnetic contact sensor is designed with a small form factor, making it an ideal choice for tight spaces and applications where size matters.

The sensor consists of a magnet and a reed switch. The magnet is securely mounted on the moving part of the door, such as the door itself or a metal track. The reed switch, which contains two electrical contacts, is mounted on the stationary part of the door frame. When the door is closed, the magnet is in close proximity to the reed switch, allowing the contacts to touch and complete the circuit. When the door opens, the magnet moves away, breaking the circuit.

This magnetic contact sensor is suitable for use with Sentrol's 2200 Series Overhead Door Opening Alarm and other compatible alarm systems. It can be used to detect the opening and closing of various types of overhead doors, including roll-up doors, sectional doors, and tilt-up doors. The sensor is rated for a maximum door height of 16 feet and a maximum door width of 16 feet.

The sensor housing is made of durable, powder-coated steel, providing protection against the elements and ensuring long-lasting performance. The sensor is easy to install, with a simple wiring configuration and a quick-connect terminal block. It can be mounted using the included mounting hardware or with optional adhesive pads for added flexibility.

The Sentrol 2205A-L Miniature Mount Overhead Door Magnetic Contact is an essential accessory for anyone looking to monitor the opening and closing of their overhead doors for safety, security, or operational efficiency reasons. With its small size, durability, and ease of installation, this magnetic contact sensor is an excellent choice for a wide range of applications.

I think its time for find them a new home. The price and shipping is for one magnetic sensor, I have three available. For some reason, I never installed them, and i've had them 'in stock' for all these years just in case could find a use. I purchased three of these overhead door magnetic sensors new in 2007 with the intention installing on our garage doors as part a home automation system project.
