Key Features of MC-38 Wired Magnetic House Security Alarm Sensor for Door and Windows
- Normally Closed (NC) Reed Switch: Circuit remains closed when the two halves are together (door/window shut); opens instantly when separated, triggering your alarm or microcontroller input.
- Simple Two-Wire Interface: No power supply needed for the sensor itself - just connect to any digital input or alarm zone; works with pull-up resistors on Arduino/ESP boards.
- Generous Gap Tolerance: Reliably detects separation up to 15-25 mm, accommodating slight door/window misalignments and thick frames.
- Compact & Discreet Design: Small white ABS housing blends into door frames, window sills, cabinets, and enclosures without drawing attention.
- Dual Mounting Options: Attach using included adhesive backing for quick installation or use screws for permanent, vibration-resistant mounting.
- Wide Voltage Compatibility: Rated up to 100 V DC, making it suitable for 3.3 V microcontroller logic, 5 V Arduino systems, 12 V alarm panels, and 24 V industrial PLCs.
- Durable & Maintenance-Free: Sealed reed switch with no moving mechanical parts exposed to wear - rated for millions of operations.
- Versatile Wired Connection: Pre-soldered leads allow easy integration into breadboards, screw terminals, or direct soldering to PCBs.
Perfect For
- DIY Home Security System: Connect multiple MC-38 sensors to an Arduino Mega or ESP32 to monitor all entry points; trigger a buzzer, send SMS alerts via GSM module, or push notifications through Wi-Fi/MQTT.
- Smart Home Integration: Use with ESP8266/ESP32 and platforms like Home Assistant, Blynk, or Tasmota to get real-time door/window open/close status on your smartphone.
- Raspberry Pi Surveillance Hub: Pair with a Pi camera - when the sensor detects a door opening, automatically capture photos or start video recording and upload to cloud storage.
- Cabinet & Safe Monitoring: Secure medicine cabinets, gun safes, or server rack doors; log every access event with timestamps for audit trails.
MC-38 Wired Magnetic Door & Window Security Alarm Sensor
Protect your home, office, or project enclosures with the MC-38 wired magnetic contact sensor - a reliable reed-switch-based security device that detects when doors or windows are opened. Ideal for DIY alarm systems, Arduino/Raspberry Pi security projects, and professional intrusion detection setups. Available from Tech Depot India, Bengaluru, with fast shipping and dedicated support.
How It Works
The MC-38 consists of two pieces: a reed switch unit (with wires) and a magnet unit. When mounted adjacent to each other - typically the reed switch on the door/window frame and the magnet on the moving door/window - the magnetic field keeps the reed switch contacts closed. When the door or window opens and the magnet moves away beyond the gap distance, the reed contacts open, breaking the circuit. Your alarm system or microcontroller detects this state change and triggers the desired response (siren, notification, log entry, etc.).
