Photoelectric sensors can be generally divided into through beam photoelectric sensors, retro-reflective photoelectric switches,diffuse-reflective photoelectric sensors and channel type photoelectric sensors. But no matter which type of sensor we need to carry out regular inspections and maintenance.

1. detect the installation position of the object and proximity sensor for deviation, slack, and skew.

2. Wiring, wiring department has no slack, poor contact, and broken wire.

3. Whether there is adhesion and accumulation of metal dust, etc.

4. Whether there is any abnormality in the use of temperature conditions and environmental conditions.

5. Whether there is any abnormality in the flashing of the set display light type.

If the inspection must be careful not to disassemble and repair on their own, corresponding to easy to find out the fault, can be connected to the portable detector to investigate the sensor action state, and then according to the situation to repair.

What is the polarization function of a sensor?

We often say that photoelectric sensors with a polarization function detect objects more accurately. Because retro-reflective photoelectric sensors may not be able to distinguish whether it is the light of the detected object or the light reflected from the mirror when detecting highly reflective objects, they are prone to failure. Polarizers can easily solve this problem by using the principle of polarization of light.

A polarizer is placed in the sensor. The polarizer is a grid with many slits, and only light waves that match its polarization direction can pass through the slits on the corresponding polarization filter (horizontal filters can only pass through horizontally polarized light waves, and vertical filters can only pass through vertically polarized light waves). When there is no object to be measured, the reflector will reflect the horizontally polarized light wave and reverse its polarization direction by 90 °, so that the return of the vertically polarized light wave can pass through the vertical polarization filter in front of the receiver and reach the phototransistor at the receiving end, the light beam forms a loop. When the object is detected, the reflected beam attenuates a lot, and the photoelectric switch outputs a signal. If the object to be detected is glass or mirror, the reflectivity is very strong, the intensity of the reflected light wave from its glass surface is constant, but the polarization direction of the light wave does not change. The reflected light is still horizontally polarized, and the horizontally polarized light cannot pass through the vertical polarizer in front of the receiver. Thus, the beam circuit is interrupted and the photoelectric switch outputs a signal because the receiver cannot receive the light wave.

Industrial rolling shutter door

Looking for a solution for industrial rolling shutter doors?

Industrial rolling doors are commonly made of two main materials, one is made of PVC soft curtain rolling doors usually called fast rolling doors or rolling shutter doors, and the other is made of aluminum alloy or steel as the material of the door body. At present, aluminum alloy material is more extensive, because of the quality performance of aluminum alloy, not easy to rust, corrosion resistance, strength, toughness, and other characteristics, the use of more extensive, longer life, often used in workshops and warehouses. But also because the aluminum alloy rolling door body is strong and heavy, if the door body slipped accidentally, the damage caused by it is also very serious. So the hard rolling door must be equipped with a higher protective infrared photoelectric sensor.
