Using Solenoids to Improve Vehicle and Pedestrian Safety
An automobile manufacturer wanted to add an infrared camera to a vehicle detection device. The solenoid was designed to move a calibration flag over the lens.
An automobile manufacturer wanted to add an infrared camera to a front-facing vehicle detection device. The device detected the thermal signature emitted by objects or pedestrians in the path of the automobile. Maintaining the accuracy and reliability of this system meant the camera needed to be calibrated when there was a drastic change in temperature. To calibrate the camera, a small flag needed to move over the lens, providing a known surface texture and color.
The TLX Solution
The infrared camera system needed a compact actuator with a fast response time. TLX Technologies designed a miniature latching solenoid that could be mounted to the circuit board. A pulse of power charges the magnet, extending the armature to move the calibration flag over the lens. Once calibrated, another pulse of power cancels the magnet, allowing the solenoid’s spring to retract the armature. This moves the flag back to its original position.
