AO-BHT-D/A Motion/Brightness and Temperature Probe for Ceiling Mounting
- motion yes/no
- 0-1 kLux
- 0...50°C
- 0-10 V, change-over contact
- holding time 5 sec. up to 15 min.
The motion brightness and temperature sensor AO-BHT-D/A measures movements in the area of 360° with a range of about 10 m by an infrared sensor, brightness from 0-1 kLux by a photo diode and the temperature from 0...+50°C.
The holding time of the motion detector can be defined by a 270° potentiometer from 5 seconds to 15 minutes.
The unobtrusive housing with snap fastening and torque/pole-protected plug is suitable for quick mounting in suspended ceilings.
The motion sensor is ideal for control processes, such as temperature and lighting control systems in offices.
