Tesla ST40 Infrared 360 Degree Motion Sensor Recessed 40mm Cut-Out 240V PIR

Description

360 degree recessed motion sensing, day or night.

The Tesla ST40 is a recessed 360 degree infrared motion sensor (PIR) that switches lighting and loads automatically when movement is detected. Fitting a 40mm ceiling cut-out, it identifies day and night automatically and offers an adjustable time delay, combining convenience, safety, and energy saving in one compact detector.

Why the Tesla ST40 Sensor Earns Its Place in the Ceiling

Full 360 degree coverage from a single point
Mounted in the ceiling, the ST40 watches a full 360 degrees around it, detecting movement up to 6 metres away. That makes it well suited to hallways, entries, stairwells, toilets, and storerooms where a single central detector can cover the whole space. It reads day and night automatically, so lights only trigger when they are actually needed — the energy-saving logic that makes automatic sensing worthwhile.

Adjustable timing for the way a room is used
The ST40 offers an adjustable time delay from around 10 seconds up to roughly 7 minutes, letting you tune how long the load stays on after the last movement. A short delay suits a quick-pass hallway; a longer delay suits a room where people linger. At approximately 0.5W standby consumption, the sensor itself costs almost nothing to run.

Recessed for a clean finish
The ST40 fits a 40mm cut-out and recesses flush into the ceiling, presenting a small, tidy face rather than a bulky surface box. It handles up to 400W of LED load (or 800W incandescent), covering typical residential and light commercial lighting circuits, and installs at a mounting height of 2.2 to 4 metres. Wiring must be carried out by a licensed electrician in accordance with Australian requirements. Tesla Electrical Components is an Australian-based brand headquartered in Wetherill Park, NSW, and this sensor is sold individually and shipped Australia-wide.

Q: What area does the Tesla ST40 sensor cover?
The ST40 detects movement across a full 360 degrees, up to 6 metres away, from a recessed ceiling position at a mounting height of 2.2 to 4 metres.

Q: Can the Tesla ST40 time delay be adjusted?
Yes. The ST40 has an adjustable time delay from approximately 10 seconds up to around 7 minutes, so the load stays on for as long as each space needs.

Q: What load can the Tesla ST40 switch?
The ST40 handles a maximum of 400W LED, 400W fluorescent, or 800W incandescent, running on 220-240V AC at 50-60Hz.
