Product Description

Description

A photoelectric switch is a device used to detect the distance, absence, or presence of an 
object by using a light transmitter, often infrared, and a photoelectric receiver. They are used 
extensively in machinery, textile, metallurgy, tobacco, railway, war industry and so on. There are 
three different functional types: through beam (opposed), retroreflective, and diffused type 
( proximity-sensing) .
 
A through beam (opposed) arrangement consists of a receiver located within the line-of-sight of the transmitter. In this mode, an object is detected when the light beam is blocked from 
getting to the receiver from the transmitter.
 
A retroreflective arrangement places the transmitter and receiver at the same location and uses 
a reflector to bounce the light beam back from the transmitter to the receiver. An object is sensed 
when the beam is interrupted and fails to reach the receiver.
 
A diffused (proximity sensing) arrangement is one in which the transmitted radiation must reflect off 
the object in order to reach the receiver. In this mode, an object is detected when the receiver sees 
the transmitted source rather than when it fails to see it.

Maintenance and overhaul
In order to ensure long-term stable operation of the photoelectric switch, please carry out the following periodic inspections;

1. Check that the installation position of the detection object and the photoelectric switch is offset, loose, and deformed.

2. Check the wiring, whether the connection part is loose or not, and the contact is broken.

3. Check for any deposits such as sticky metal dust.

4. Check the operating temperature and whether there are any abnormalities in the surrounding environment.
