10 Types of Sensor 

Sensors directly acquire non-electrical signals from the environment or system (such as temperature, pressure, light, displacement, and velocity) through sensitive components. These signals are converted into standardized electrical signals (such as voltage, current, and frequency) according to specific patterns for subsequent system processing or control.

Sensor Types

1. Photoelectric switches, short for photoelectric proximity switches, detect the presence of an object by blocking or reflecting a light beam. A synchronous circuit activates the circuit, enabling the detection of the object. They are often used in industry to count the number of robot arm movements.

Famous manufacturers: SICK, Panasonic, OMRON, euze, Autonics, ifm, BALLUFF

2. Proximity Switches

A proximity switch is a position switch that operates without direct mechanical contact with a moving part. When an object approaches the switch's sensing surface within the operating distance, the switch actuates without mechanical contact or pressure. Proximity switches, also known as contactless proximity switches, are ideal electronic switching sensors.

They are widely used in industries such as machine tools, metallurgy, chemicals, textiles, and printing.

3. Fiber Optic Sensors

Fiber optic sensors are sensors that convert the state of a measured object into a measurable optical signal.

4. Safety Light Barriers

Safety light barriers are photoelectric safety devices (also known as safety protectors, press protectors, infrared safety devices, etc.). Generally, safety light barriers come in pairs, with a transmitter and a receiver.

5. Pressure Sensors

A pressure sensor (pressure transducer) is a device or device that can sense pressure signals and convert them into a usable electrical output signal according to a specific pattern.

Pressure sensors typically consist of a pressure-sensitive element and a signal processing unit. Depending on the test pressure type, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors, and absolute pressure sensors.

6. Label Sensors

Label Sensors (Label Sensors) A sensor is a sensor used to detect and read labels, tags, or identifiers.

7. Laser Sensor

A laser sensor uses laser technology for measurement. It consists of a laser, a laser detector, and a measurement circuit.

8. Color Mark Sensor

A color mark sensor detects various labels.

9. Ultrasonic Sensor

An ultrasonic sensor converts ultrasonic signals into other energy signals (usually electrical signals).

10. Magnetic Switch

A magnetic switch, also known as a magnetically controlled switch, is a small device that uses a magnetic field to control a circuit. A magnetically controlled switch is also known as a magnetic switch intrusion detector.
