Proximity sensors use specialized methods to detect or measure objects without moving them physically. The 9964-3400 is one type of proximity sensor that has an array of potential uses and a special working principle.

The 9964-3400 is a type of infrared distance measuring sensors that use non-contact technology to measure results. It has a variety of applications, such as border control, robotics, collision prevention, printing, materials handling, and many more. With their ability to detect objects or measure distances with no contact, they are also ideal for harsh environments where manufacturing processes are done in hostile conditions. Furthermore, the infrared technology of these types of proximity sensors can measure from 100 cm to 3 m with millimeter accuracy, making them suitable for precise detection.

The 9964-3400 works by using infrared LED light and a near infrared light detecting IC. It emits modulated infrared light and receives it back when it reflects from obstacles or objects in front of it. This reflection of light signals the device and produces a pulse with a certain frequency and a certain distance.

It uses a modulated 38KHz infrared light with a one millisecond pulse output of 262 pulses. The receiving IC can sense these pulses and has a time interval counter that measures the pulse width ratio (PWR), which can then be used to calculate distance. It also has an erase function, which eliminates the effects of previously received pulse signals, making it immune to interference.

The distance calculation is based on the round-trip time of the infrared pulse. The round-trip time is converted to time interval as an electrical signal, and then the Timing Interval Counter (TIC) is used to measure the pulse width ratio (PWR). The PWR is then used to calculate the distance, giving the device its millimeter accuracy and range from 100 cm to 3 m.

The 9964-3400 proximity sensor is an ideal device for detecting objects or measuring distances without physical contact. With its non-contact technology, it has a wide array of applications in many different situations. Furthermore, its modulated infrared light and pulse output allows for millimeter accuracy from 100 cm to 3 m, making it even more versatile and useful in many industrial and robotics processes.
