Description
The MC-38 magnetic switch sensor comes in a pair consisting of a Reed Switch and a magnet. The wired part of the module is the reed switch, whereas the other part is the magnet. It is commonly used as a home security alarm system.
The sensor consists of two main parts, a magnet and as switch with terminals to connect the signal wires. The magnet mounts to a door or access panel, while the switch mounts to the frame. When the door is closed the two pieces should be in close contact of each other. When the door opens this distance increases, eventually toggling the switch. This allows to know when the door is open.
Features and Specifications of MC-38
Below are some features and specifications of the MC-38 magnetic switch.
- Model: MC-38
- Color: White
- Voltage: DC 100-110V
- Rated Power: 10W
- Contact Capacity: 0.5Amp Current Switching Maximum
- Operating distance: 15 – 25mm
- Cable Length: 30cm ± 10mm
- Sensor Output: Normally Open (the circuit is open normally, and, circuit is connected when magnet is near.)
Note : The metal reeds on a normally open switch stay open when there is no magnet near the switch. In the presence of a magnetic field, the contacts of a normally-open reed switch will close.
Applications of MC-38
Here are some of the applications of this MC-38 module.
- Can be used at doors or windows to know the open and closed state
- Used to detect an intruder activity
- Home Alarm system
