Product Overview
The BBDM-40KR12M is a 40 kHz ultrasonic transducer for air-distance measurement from 0.35 to 12 m. Long-range, standard-beam and narrow-beam configurations are available for position sensing, proximity detection, vehicle monitoring, robotic obstacle avoidance and industrial distance measurement.
Key Features
- Reference detection distance up to 12 m
- 12°, 14° and 15° beam options
- IP65 or IP66 protection configurations
- Multiple cylindrical housing sizes
- Optional integrated thermistor
