What are discrete sensors? What is machine vision?

Discrete sensors measure presence, proximity, distance, vibration, direction, motion, and other parameters and often are named by function or technology, such as proximity sensor or laser sensor. Machine vision is a type of device that uses sensors and software to see, collecting measurements, analyzing inputs and recording or deciding based on the measurement (most simply, pass or fail, in a quality inspection application), often triggering an actuator to reject a faulty part.

Picking the right discrete sensor for a machine application

There are many considerations for picking a discrete sensor for a machine application. These include if the sensor is being used for position detection or part detection or if the application is hazardous. See four factors for industrial sensor specification.
