Photoelectric switch housing has plastic or metal housing, cylindrical, square, fork, glass or plastic fiber optic, etc. Direct-light system detection distance is long, suitable for large 100m, detecting opaque objects accurately and reliably, good resistance to harsh conditions (dust, scattered light guide) Reflection system detection distance is medium, suitable for large 15m, easy to install, detecting opaque objects or non-reflective transparent objects; polar reflection system can detect Reflective objects diffuse system detection distance.
Optical switch installation precautions are as follows:
1.Please follow the wiring method in the operation manual for cable renewal, this product is not suitable for solutions or viscous liquids containing adhesive suspensions, this product may not operate properly in some emulsions and semi-solid liquids.
2.Installation and use, please do not scratch the probe, SD22 probe and the body of the manual turning torque of about 10 kgf-cm.
3.The recommended installation method is as follows, and the horizontal surface from parallel 0 ° to tilt angle between 45 ° is suitable for good installation angle, photoelectric switch front cone radius of 30mm, there must not be any reflective surface or other interference.
4.Photoelectric switch cone sensor front and barrel wall distance of at least 30mm, photoelectric switch installation threaded casing, photoelectric switch sensor head must be exposed to the casing.
Avoid using in the following places, generally may cause the photoelectric switch misoperation, try to avoid.
● Places with more dust.
● Places where there are more corrosive gases.
● Places where water, oil, and chemicals are likely to splash directly.
Places where there is direct light from outdoor or sunlight without shading measures.
● Places where the ambient temperature changes beyond the range specified in the product.
● Places where vibration and shock are large and no shock-absorbing measures have been taken.
I hope the above can help you to install and use the photoelectric level switch correctly.
