Ruth's sister

Ruth's sister 40mm LED PIR Motion Sensor Switch

SKU CH-1ZGZ-7HFCY

A 40 mm PIR motion sensor switch controls lights up to 40 W with adjustable time delay and three photosensing levels

  • Auto on/off saves energy with infrared motion detection
  • Adjustable time delay of 15 seconds to 5 minutes suits any room
  • Three lux settings from 2 to 2000 prevent false triggers
  • Wide 110° coverage detects movement across 4-6 metres
  • Operates on AC 100-240V for global compatibility

40 mm PIR motion sensor switch

The 40 mm LED PIR detector switches lighting loads automatically by sensing infrared heat from a person. It suits energy‑saving lamps, LED lamps and fluorescent fixtures in corridors, cupboards or utility rooms. Installers who need a compact, mains‑powered presence switch will find it fits standard junction boxes.

Time delay adjustable 15 s to 5 min

Three selectable delays — 15 secs, 45 secs and 5 mins — let the installer match the hold time to the space. The unit draws negligible standby power and runs on AC 100‑240 V at 50 or 60 Hz. Maximum connected load is 40 W, so total lamp wattage must stay below that figure.

Photocell settings 2 lux to 2000 lux

An integrated light sensor offers three thresholds — 2 lux, 25 lux and 2000 lux — preventing daytime activation. Detection covers 110 ° at 4‑6 m and operates from ‑10 °C to +45 °C. Copper cable tails simplify wiring, while the white 45×40×25 mm housing keeps a low profile on ceilings or walls.

Questions about this item

How do I wire the 40mm PIR sensor into a 100-240V AC lighting circuit and which step is most often missed?

Connect live, neutral and load wires to the marked terminals, then select the 2, 25 or 2000 lux photosensing setting before sealing the enclosure; the step most often missed is setting the lux threshold for the ambient light level.

What maintenance will the sensor need after installation?

The unit has no user-serviceable parts; maintenance is limited to occasional cleaning of the 110° detection lens with a dry cloth to keep the 4-6 metre sensing distance accurate.

At what point does the 40W output limit become the bottleneck during continuous operation?

The 40W maximum load is the first limit reached; if the connected lamps exceed 40W the sensor will overheat or trip, so total lamp wattage must stay at or below 40W.
