Overview
What it is
Helios 2T is a combination sensor for industrial doors. A 24.2 GHz microwave (radar) field handles opening, while a double row of active infrared (AIR) spots watches the area close to the door so it stays open while someone is still there.
What it is used for
It suits high-speed, roller and sectional doors where forklifts, trucks and pedestrians share the same opening. The sensor can ignore cross traffic and people who do not need the door, which shortens open times and helps keep heated or cooled buildings efficient.
Key features
- Radar activation field plus AIR presence curtain in one housing.
- Configuration through a free Android and iOS app, available in seven languages.
- Individual AIR spots can be switched on or off in the app.
- Extra AUX output, for example to drive a warning light when a vehicle approaches.
- LED ring shows operating status.
- IP65 and NEMA 4 rated, -35 to +55 °C.
Buying considerations
Outputs are PhotoMOS solid-state contacts rated at 50 V AC/DC and 0.3 A: a Form A activation output, a Form A AUX output and a Form B output for supplemental safety. Check that your door controller inputs fall within this rating.
Installation considerations
Bircher states mounting heights up to 6 m. The radar and AIR fields are angled independently with side screws and a printed scale. The box includes the sensor, mounting bracket, screws and plugs, and a 10 m control cable with a plug-in connector. Supply is 12 to 24 V AC or 12 to 30 V DC.
Compatibility
Works with industrial door controllers that accept potential-free activation and safety inputs. Bircher lists Herkules 2E and EasyLoop alongside it in the industrial door range.

Questions about this product
How is Helios 2T configured?
Through the Helios mobile app for Android and iOS, which Bircher offers free of charge. Detection fields and individual infrared spots are adjusted there.
Does Helios 2T only open the door or also keep it open while someone is underneath?
Both. The radar field activates the door and the double row of active infrared spots provides presence detection near the door, with a separate Form B safety output.
