What is Proximity Sensor : Top Manufacturer Companies

A proximity sensor is an electronic sensing device that detects the presence or movement of nearby objects without physical contact. These sensors are widely used in industrial automation, automotive electronics, consumer devices, robotics, smart buildings, and manufacturing systems to improve safety, efficiency, and operational control.

About Proximity Sensors

A proximity sensor detects the presence of an object or person without needing to physically touch it.
When choosing a proximity sensor for your system, consider these key specifications:

• Operating range or distance: How far away can the sensor detect an object?
• Operating temperature: What temperature range can the sensor function in?
• AC or DC power: What type of power supply does the sensor require?
• Output: What kind of signal does the sensor output (current, voltage, resistance, frequency)?
• Load: What type of load (AC or DC) can the sensor handle?
• Switch type: Is the switch normally open (NO) or normally closed (NC)?
• Interface type: Does the sensor use a specific serial interface or other communication protocol?
