Description

Magnetic Reed Switch Price in Kenya

The current sale price is KSh 450, reduced from KSh 500. This normally closed magnetic reed switch detects the opening of a compatible door or window.

What Is a Magnetic Reed Switch?

A reed switch changes electrical state when its magnet moves away from the sensor, allowing a connected system to detect opening.

Magnetic Door Sensor for Alarm Systems

The two-part contact connects to a compatible alarm zone and reports when the protected door is opened.

Normally Closed Door Contact

The supplied contact is normally closed by default. Confirm the alarm panel’s required contact type and supervision arrangement.

Reed Switch Sensor Operation

With the door closed, the magnet sits beside the switch. Opening the door separates both parts and changes the dry-contact output.

Dry Contact Output

The switch provides a dry contact rather than supplying voltage. The connected panel or controller monitors the circuit state.

Magnetic Door Switch Installation

Mount the sensor on the fixed frame and the magnet on the moving door, keeping both parts correctly aligned when closed.

Reed Switch for Windows

The contact may also suit compatible windows where both parts can be mounted securely with a consistent closing gap.

Magnetic Reed Sensor vs Vibration Sensor

A reed switch detects actual opening, while a vibration sensor detects impact before or during a forced entry. They can be used together.

Using a Door Sensor as a Control Switch

Dry-contact door sensors may connect to compatible controllers for status or switching functions. Never connect an unsupported load directly.

Testing a Magnetic Reed Switch

Open and close the door several times and confirm that the connected panel consistently changes state without intermittent alarms.
