Optical Sensors - Photointerrupters - Slot Type - Logic Output

SF4-AH12-H is a type of optical sensor from the slot type photointerrupter series. It features a long sensing distance and a logic output signal. This sensor is designed to detect clearance, broken wires, missing parts, misassembled products and other design fault in narrow spaces and miniaturized apparatus.

Application Fields

SF4-AH12-H is specially designed for narrow space detection and detection of missing parts. It can be used in printing machines, paper and textile machines, injection molding machines, packaging machines etc. It is also suitable for detection of presence, absence or obstacle in conveyor belts and contactless position control in narrow spaces.

Working Principle

SF4-AH12-H is a photointerrupter, and its working principle is based on an optical slot type sensor module. Its sensing distance reaches up to 8mm, and it can detect the tiny changes of an object passing through its optical slot. It converts detection result into a logic output signal so it can be easily connected to other digital devices like a microcontroller. It can also work at a high speed with an output switching frequency up to 500kHz.

The SF4-AH12-H optical sensor has an auto power-on sensing property. It operates on a 5V power supply and consumes a rated current of only 0.4mA. This sensor is small in size, light in weight, and is composed of a control board and interior structure. Its structural design makes it resistant to dust, vibration, heat, humidity and other environmental conditions.

Conclusion

The SF4-AH12-H is a type of optical sensor from the slot type photointerrupter series. It features a long sensing distance and a logic output signal and is suitable for detection of presence, absence or obstacle in conveyor belts and contactless position control in narrow spaces. Because of its auto power-on sensing, small size, light weight, and resistance to dust, vibration, heat, humidity and other environmental conditions, SF4-AH12-H is a suitable choice for many industrial applications.
