Emerson PIR Motion Sensor Light Switch 2-Pack

This Emerson 2-pack provides PIR motion sensor light switches for automatic lighting control. Each unit operates on AC 100-240V and supports loads up to 40W for LED strips, bulbs, fans, or doorbells. The switches install through a 25mm mounting hole with a 4-wire plug-and-play connection. Two switches are included for multi-room coverage.

Suits homes wanting adjustable hands-free lighting

These switches suit installations that need adjustable LUX sensitivity across three modes and selectable time delays of 15 seconds, 45 seconds, or 5 minutes. The 110-degree detection angle covers wide areas at 2-6 meter range. Buyers who need wireless smart-home integration, app control, or voice-assistant linking should look at a different product class because this model uses a corded electric protocol only.

25mm mounting hole decides fit

The single specification that decides whether this is the right part is the 25mm hole opening diameter required for panel mounting. If the ceiling, wall, or cabinet cannot accommodate a 25mm cutout, the switches will not install. The compact dimensions of 5.2 x 1 x 3.4 inches allow placement in tight spaces once the hole requirement is met.

Questions about this item

What size mounting hole does the Emerson PIR sensor need?

Each unit requires a 25 mm (0.98 in) diameter cut-out for panel mounting.

Which wiring step is most often missed during installation?

The four-wire plug-and-play harness must be connected to live, neutral, load and the sensor lead; omitting the load wire leaves the light permanently off.

How long will the time-delay relay operate before it may need replacement?

The switch offers three selectable delays of 15 s, 45 s or 5 min; the internal relay is rated for the product’s standard service life and has no user-serviceable parts.
