PM-R65W-P

Optical Sensors - Photointerrupters - Slot Type - Logic Output

The PM-R65W-P is a type of logic output slot-type photointerrupter, which is a type of optical sensor. It is used as an input or output interface between electrical circuits, and can be used in a variety of applications such as detecting the presence of objects, measuring distances, or for automatic control. This article will explain the application field and working principle of the PM-R65W-P.

Applications of PM-R65W-P Photointerrupters

The PM-R65W-P photointerrupter is an analog, shielded, and low-profile slot-type device. Its features make it suitable for a wide range of applications, such as detecting the position of objects in automatic control systems, precision distance measurement, and proximity detection. It can also be used as an interface between circuits for efficient and reliable data transmission.

Additionally, due to its small size and low power consumption, the PM-R65W-P is suitable for use in tight spaces where power saving and reliability is essential. Its low-profile design also makes it ideal for use in physical space-constrained settings, such as in medical devices, automotive applications, and household appliances.

Working Principle

The PM-R65W-P photointerrupter consists of an emitter and a receiver, as well as a two-wire cable and a logic output connection. The emitter is an LED which emits infrared light when powered up, which is then received by the receiver. When an object passes through the slot, the infrared light is blocked by the object and the receiver stops receiving this light. This causes the logic output to switch to a low status for as long as the object is there.

The receiver has two modes of operation: synchronous and asynchronous. In synchronous mode, the receiver is triggered when the LED is turned on and the receiver stops receiving when the LED is turned off. In asynchronous mode, the receiver is triggered when the LED is turned off and it stops receiving when the LED is turned on.

Conclusion

The PM-R65W-P photointerrupter is a versatile optical sensor which can be used in a wide range of applications for automatic control, precision distance measurement, proximity detection, and data transmission. It has a low profile design and low power consumption, making it suitable for space-constrained settings.
