MOS-04-VS-WH
Opening sensor
| Model number: | MOS-04-VS-WH |
|---|---|
| Mounting: | Surface mounting on movable panels (doors, windows, cabinets) |
| Packaging: | 1 Pack = 10 sensors |
General description
MOS-04-VS-WH is a magnetic NC (Normally Closed) contact sensor with wired connection, designed for detecting the opening and closing of doors, windows, or cabinets. It provides a closed contact when the magnet is present, making it suitable for intrusion detection, 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.
- Surface mounted design – suitable for visible installation on doors, windows, cabinets, or movable panels.
- Wired connection.
- Designed for use with HIQ systems.

Integration Notes
Dry contact output:
- MOS-04-VS-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 aligned and installed within the specified operating gap distance to ensure reliable detection.
Electrical limits:
- The switching voltage, current, and power ratings must not be exceeded to avoid damaging the reed contact.
