Photoelectricity protector, also is called the safe light curtain, the security light grating, is through launch infrared, has the protection light grating, when the light grating is interdicted, the device sends out the interrupting signal, to control which has the potential hazard mechanical device stop working, reduces the possibility of the operating personnel to receive the injury in the working conditions , protects operating personnels personal safety effectively.
The products divide into two kind of type, five series:
ST photoelectricity protector, also divides into the STF series, the STD series, the STQ series, mainly uses in the large-scale press machinery and presswork, the shearing equipment and metal cutting equipment, the robot assembly line, the machinery welding assembly line, the machine-finishing power transmission sequence, as well as other greatly dangerous region protection.
SN photoelectricity protector, also divides into the SNA series, the SNB series, mainly uses in the small press machinery and presswork, the shearing equipment and metal cutting equipment, the machine-finishing equipment, casts the machinery, the paper cutting machinery, the carpentry processes the machinery, the three-dimensional garage, as well as other dangerous region protection.
The SN series, the ST series photoelectricity protector has following characteristic:
1. The product structure is simple, the wiring is convenient
The signal cable uses the whorl type aviation plug-in unit connection
2. The product specification is enough to select
STF series, protection height 120-1560mm, protection range, 400-3000mm;
STD series, protection height 120-1560mm, protection range, 0-10000mm;
STQ series, protection height 120-1560mm, protection range, 0-12000mm(2 sides), 0-8000mm;(3 sides);
SNA series, protection height 100-1560mm, protection range, 0-2000mm;
SNB series, protection height 100-1560mm, protection range, 0-5000mm;
3. The product refers to the European standard to design, Safe reliable
4. The product self-checking function is perfect
When the photoelectric protector loses the electricity or oneself appears the breakdown, the product can insure does not transmission incorrect signal to the electric circuit controlled
5. Product running status instruction
Product running status is instructed through indicating lamp and LED锛?and may use this instruction assistance sensors to align and to carry on the fault analysis.
6. The product has the fast response ability
Response time锛?0ms, enabled the system the greatest degree to avoid the danger.
7. The product uses the double relay safety signal output
The product can guarantee to the electric appliance which controls does not output the incorrect signal, so that the security is strengthened maximum limit.
8. May provide NPN or the PNP output. This time the user should insure the following control circuit of the mechanical device be safe and reliable.
9. May establish the self-preservation function (user choice)
When the light curtain is interrupted, the press slide stops movement. While the light curtain restores passing, the press slide cannot move again, until the reset button is press down.
10. The product has better anti-jamming ability
To the electromagnetism signal, the intense lamp light, the arc of welding has better anti-jamming ability
11. Is easy to use.
The product service life is long (relay removable)
12. The product vibration-proof performance is good
