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 typical tangential reach r ≈ 12.5 m reliably covers entrances, façades and building corners (a corner bracket is included). Commissioning and networking are done via Bluetooth® Mesh in the STEINEL Connect app — create groups, copy settings and fine-tune time/twilight parameters with your phone. Eagle Eye improves head-on detection, Sneak-by guard prevents “walk-by” gaps and the sensor supports segment masking for precise zoning.
Dimming (uDIM) — important
- uDIM is built into the sensor (phase-cut dimming; works with both leading and trailing edge drivers).
- Make sure the luminaire/LED driver is dimmable — otherwise dimming will not work.
- Features include soft light start and configurable basic light level/time from the app.
Where it fits best
House and apartment block entrances, façades, porches/terraces, garages, driveways and paths where 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 lamp/driver used; on-site testing is recommended. The connected luminaire must be dimmable.
