collision sensor
A collision sensor is a piece of electronic safety equipment that detects an impact through vibrations. Collision sensors are also known as impact sensors.
Collision sensors are used in many industrial settings, including manufacturing and utilities. The sensors are also used in consumer goods, such as in collision avoidance and detection systems in cars. Impact sensors are similarly used in many types of robots to prevent damage to products, tools and the robot itself.
In many settings, quick detection of collisions with unexpected objects can reduce damages, costs
In less complex devices, collision sensors use a simple pressure switch connected to a surface that is likely to encounter collisions. They may also use accelerometers that measure gravitational force changes, with rapid changes and high forces indicating an impact from an unexpected collision.
