Diffuse reflection type photoelectric switch is made up of light projector and light receptor, which is one of standard configurations.When the light beam comesfrom the projuctor, the target creates diffuse reflection;when there is enough combination light back to the light receptor, the switch state will change;Effectiveoperating distance depends on the reflectibe capacity of the target, as well as the surface property and color.Teh change capacity with sensitivity adjuster can assumecompensation action;The equipment has lower consumption.When the optical sensor is made up of a single element, rough location can usually be achieved;Adoptsthe function of background rejection to regulate the measuring distance;sensitive to the dust on the target and sensitive to the changed reflective performance of thetarget.

Matters Needing Attention when using photoelectric switch
Ways to avoid mutualinterference
When the photoelectrie switchapproaches to the equipmen,the light from another switch emits,causing unsteady acion, whichis caled mutualintererence; The light projetor and thelight eceptorare cros-installed mulualy; When the refiecion type isused together, the distance betweenthem mustbe kept,and the et distance is 1.4 times of detection distance; When the correlation type is used togcther,the distance between them must be kept, and the set distance is 0.4times ofdetection distance.
Prevent wiringinterference method
The Pholoelectrie switch mustbe equipped individually with metal flexible pipe, and don’ make it withthe eletrie line and power ine in the same metal fexible pipe; The supply voltage must inside the supply voltage range.
Installations ofthe matters needing attention
Wherethere is more dust; Where there is morecorosive gas; Where water,oil anddrugs are sprayed straightly; Where intense lightsuchas sun light shines directly; When it’s during the use, the ambient temperature and hu midity must be inside the rated range.
