Sensaphone® Window/Door Sensor
Magnetic reed switch for Sensaphone remote monitoring systems
Our take on the Sensaphone® Window/Door Sensor by Crutchfield's Tara W.
Use this switch with a Sensaphone system to detect unauthorized entry through a window or door. It installs easily using the included hardware and connects to your system with 22-gauge accessory wire (not included). Connect multiple switches together to monitor more doors and windows.
What's in the Box:
- Magnetic plate
- Connector plate
- Plastic bracket
- Plastic spacer

Overview: The Sensaphone Magnetic Reed Switch detects unauthorized entry or intrusion. It can be used with most windows or doors and is compatible with all Sensaphone monitoring systems. The Magnetic Reed Switch enables your Sensaphone to detect if any unauthorized entry or intrusion has occurred. Switches are usually installed on doors and windows to detect their opening or closing. The complete Magnetic Reed Switch assembly comes in two main parts; a magnet in a plastic housing, and a switch with screw terminals in another separate plastic housing. This unit does not come with wire for installation but does include hardware four mounting.
