Product Description

Features

The PF21 series of mini-type photoelectric sensors is a new and upgraded product. It includes through-beam, polarized reflective, and diffuse types of sensors

• Aspherical optics completely eliminate stray light and the special optical structure is highly light-resistant
• Red LED indicates working status for easy installation
• Long sensing distances, 15/30 meters for the Opposite-beam type 
• Large spot size for good visibility and easy adjustment of the optical axis
• High immunity to stray light, dust, and other fine particles
• Output and stability indicators are brighter than conventional models and easy to see from any direction
• Widely used in different business areas such as automatic doors, warehousing and logistics, intelligent parking and access gates
• Protection rating IP67, compact design ensures application and installation in limited space

Packaging & Shipping

 

Product self-inspection steps

1. Detect whether the installation position of the object and the proximity sensor has deviated, slacked, or skewed; whether there is slack, poor contact, or disconnection in the wiring and connection parts
2. Whether there is adhesion or accumulation of metal dust, etc.
3. Is there any abnormality in using temperature conditions and environmental conditions?
4. Set whether the flashing of the display lamp type is abnormal.
If you must be careful not to disassemble and repair by yourself during the inspection, and to easily find out the fault, you can investigate the operating state of the sensor through the connection with the portable detector, and then repair it according to the situation.

In order to make the photoelectric sensor work stably for a long time, it should be regularly checked with the same contents as the general control equipment to maintain its long-term function. The photoelectric sensor can also be stocked. Once a problem with the photoelectric sensor is found, we can replace it in time without affecting the use of the sensor.
