===== General description =====

MOS-03-HD-WH is a magnetic NC (Normally Closed) recessed contact sensor designed for flush-mounted installation inside doors, windows, cabinets, or panels to detect opening and closing events. The recessed installation provides a discreet and tamper-resistant solution suitable for security and automation system integration.


===== Features =====

  * Normally closed type **(NC)**: when the magnet is  close to switch, the contacts are closed.
  * Sensor is a reed switch, operated by an applied magnetic field.
  * ABS housing – durable plastic enclosure suitable for indoor installations.
  * Recessed (hidden) mounting – designed for flush installation inside frames or panels for improved aesthetics and increased tamper resistance.
  * Compact micro design – suitable for installations with limited space.
  * Terminal connection – allows flexible field wiring during installation.
  * Designed for use with HIQ systems.

===== Integration Notes =====

**Dry contact output:**
  * MOS-03-HD-WH provides a mechanical reed contact output and does not generate voltage signals. The receiving device must support dry contact inputs.

**NC operation logic:**
  * The circuit remains closed while the magnet is aligned with the sensor. When the door or window opens and the magnet moves away, the circuit opens and triggers the monitoring system.

**Installation positioning:**
  * The sensor and magnet must be installed inside aligned drilled holes to ensure proper operation and maintain the specified sensing gap.

**Electrical limits:**
  * The switching voltage, current, and power ratings must not be exceeded to avoid damaging the reed contact.

**Wiring and Terminal Information:**
  * MOS-03-HD-WH is supplied without pre-installed wires and is designed for field wiring using small integrated screw terminals. The terminals use cross-head screws, allowing secure conductor attachment during installation. The maximum supported conductor cross-section is 0.5 mm², ensuring reliable electrical connection while maintaining compact terminal dimensions.
