Dual-Door Cabinet LED Sensor Switch, Integrated or Separate
See inside a cabinet when you open either door, without reaching for a separate light switch. This dual-door sensor connects to a compatible low-voltage LED control system. It is for cabinet-lighting projects where the sensor type, voltage and three-contact pin order can be matched.
- ✅ Bring light on when reaching inside — The dual-door function turns the connected LED lighting on as either door opens.
- ✅ Avoid leaving a closed cabinet lit — Closing both doors turns the connected lighting off.
- ✅ Choose a sensor layout for the cabinet — Integrated and separate-head versions offer different mounting arrangements.
- ✅ Route the sensor lead back to the control unit — Each selected sensor assembly includes a connection cable.
Match the sensor body and contact order
New Door Sensor A and B use the integrated rectangular dual-sensor body. Door Motion Sensor A and B use two separate cylindrical heads. Variant images identify A as + S − and B as − S + at the three-contact connector. Match the control unit's exact socket and contact order; the similar connector shapes do not make A and B interchangeable.
The integrated body is approximately 40 × 30 × 10 mm, with a nominal 1.8 m lead, DC 12–24 V input and stated limits of 60 W at 12 V or 100 W at 24 V. It mounts centrally near the meeting edges of the doors. The separate-head type is specified at DC 5–24 V, with a 2.5 m lead and limits of 60 W at 12 V or 120 W at 24 V.
The separate heads are approximately 12 mm in diameter and 12 mm high, with a 10 mm recess hole illustrated. One selected sensor assembly and its lead are supplied, not both formats. The lighting, LED driver/control distribution box and cabinet are not included; connect only to a matched low-voltage system, never directly to mains.
Opening either cabinet door can switch on matched low-voltage LED lighting.
The integrated body and its lead form one sensor option.
The integrated version has a three-contact port and a compact rectangular body.
Position the integrated type centrally so both door edges align with the sensors.
The integrated body has a removable mounting plate.
Separate heads allow a different layout for the two door positions.
The separate-head option uses small cylindrical sensors with a longer lead.
One or both open doors keep the connected cabinet light on.
Separate heads can be surface mounted with clips or recessed into suitable holes.
