Product Description
Steinel MD IR N270 uDIM is a professional outdoor PIR motion sensor for wall surface-mount applications. The wide 270° detection angle with a typical tangential reach of approx. 12.5 m reliably covers entrances, façades and building corners (a corner wall bracket is included). Commissioning and networking are done via Bluetooth® Mesh in the STEINEL Connect app — create groups, copy settings and fine-tune time (5 s–60 min) and twilight (2–1000 lx) directly from your phone.
Dimming (uDIM) — important
- uDIM is built into the sensor: phase-cut dimming compatible with both leading and trailing edge LED drivers.
- The connected luminaire/LED driver must be dimmable; otherwise dimming will not work.
- Supports soft light start (smooth switch-on) and configurable basic light level/time from the app.
- With LED loads, behaviour can vary between drivers at low dim levels — on-site testing is recommended.
Where it fits best
House and apartment block entrances, façades, porches/terraces, garages, driveways and paths — anywhere you need wide coverage, reliable detection and app-based setup.

Electrical load (uDIM)
| Resistive | 1000 W |
| Fluorescent, electronic ballast | 500 W |
| Fluorescent, uncorrected | 400 VA |
| LED < 2 W | 100 W |
| LED 2–8 W | 300 W |
| LED > 8 W | 600 W |
Note: actual switching/dimming capacity depends on the connected lamp/driver and installation conditions. The luminaire must be dimmable.
