What is sensor?
A sensor is a sensing element that converts physical quantities such as pressure, temperature, humidity, etc., into continuous (analog) or discrete (digital) electrical quantities. These sensors are used in various measuring devices, analog and digital control systems such as PLCs. The performance of sensors and their ability to connect to various devices like PLCs have made them an inseparable component of automatic control systems. Sensors send various information about the status of a system's moving parts to the control unit, causing changes in the operation of devices.
Non-Contact Sensors
Non-contact sensors are sensors that detect the presence of an object as it approaches and become active. As shown in the figure below, this action can result in the activation of a relay, contactor, or the transmission of an electrical signal to the input stage of a system.
