Proximity Sensors: 9982-4265 Applications and Working Principle

Proximity sensors are devices that can detect the presence, absence, and/or distance of an object while in an environment. They are commonly used in automation, safety, and security applications, where they can provide levels of protection and performance when an object enters a monitored area. The 9982-4265 proximity sensor is a self-contained, ultra-compact sensor able to detect metal-free objects at a distance of up to 8 inches. It is designed for use in a variety of applications such as security, robotic movement, and inventory control.

Proximity Sensor Operation

Proximity sensors use one of several sensing technologies to detect the presence, absence, and/or distance of an object. These technologies include ultrasonic, infrared, capacitive, and inductive sensing.

Ultrasonic Sensing

Ultrasonic sensors generate high frequency sound waves and measure the time it takes for the sound to travel to the sensing object and return. When the object moves within the field of view of the sensor, the return time changes, triggering an alarm. The 9982-4265 proximity sensor uses ultrasonic sensing technology.

Infrared Sensing

Infrared sensors use infrared or laser beams to detect objects in their field of view. When the beam is interrupted, the object is detected. They are commonly used in range finders, or short range surveillance applications.

Capacitive Sensing

Capacitive sensors detect objects by sensing changes in electrical capacitance. A capacitive sensor works by transmitting an electrical field and detects changes in the electrical field. This type of sensing technology is often used in remote control and touch-sensitive devices.

Inductive Sensing

Inductive sensors detect objects by emitting an electromagnetic field and measuring changes in the field. This type of sensing technology is often used in proximity switches and proximity detectors.

9982-4265 Proximity Sensor

The 9982-4265 proximity sensor is a self-contained, ultra-compact sensor. It uses a radio frequency signal to detect metal-free objects within 8 inches of its sensing range. The sensing range is adjustable and can be programmed using the included software. The sensor can also be configured to detect a specific object size, or range of sizes.The 9982-4265 is designed for a variety of applications, including security, robotic movement, and inventory control. It is equipped with a red LED indicator light that illuminates when an object is detected. The LED can be dimmed or turned off for specific applications. The sensor also has reverse polarity protection, allowing it to be used in either positive or negative potential systems.

Conclusion

The 9982-4265 ultra-compact proximity sensor is designed for a variety of applications such as security, robotic movement, and inventory control. It uses ultrasonic sensing technology to detect metal-free objects within 8 inches of its sensing range. The adjustable range makes this sensor suitable for many applications and the reverse polarity protection ensures proper operation in both positive and negative potential systems. The red LED indicator light provides both visual and audible feedback when an object is detected.
