Photoelectric Proximity Sensors
These sensors use light to detect the presence or absence of an object. They emit a light beam and measure the amount of light received. If the beam is interrupted by an object, the sensor …
Engineering Roles
Ultrasonic Proximity Sensors
Ultrasonic proximity sensors are electronic devices that use sound waves at ultrasonic frequencies to detect the presence or proximity of objects. They work based on the principle of sound wave reflection and measurement of the …
Capacitive Proximity Sensors
Capacitive proximity sensors are electronic devices used for non-contact detection of objects based on changes in capacitance. They operate by generating an electrostatic field and measuring changes in capacitance when an object enters the sensing …
Inductive Proximity Sensor
An inductive proximity sensor is a type of sensor used to detect the presence or absence of metallic objects without physical contact. It operates based on the principle of electromagnetic induction. The sensor consists of …
Types of Transformer
Power transformers are classified based on several factors, including their purpose, construction, and voltage levels. Here are some common types of power transformers:
