Usage
The Photoelectric Protector is also named Safety Light Curtain, Safety Grating and so on. It is mainly
used for mechanical processing equipment, hazardous work areas, machinery and equipment to
prevent injury to the operator and caused injury or accident by into the dangerous region, to protect
personal safety.
The protector can achieve all trip protection for press which its slide could be stopped by brake at
any place in its slide’s trip, or can achieve protection of the trip between 30°~180° by using cam.
Using the protector in industrial manipulators, mould shapers, packaging equipments, automatic
equipments, jointing pipelining and other operating regions with danger, it can give an alarm after
entering the hazardous area or interlock with the safety system of the equipment, to protect personal
safety.

Specifications Varieties, Application Wide
The protective height of conventional products
is from 113mm to 1493mm;
Pefect self-checking function
Ensure that the photoelectric protector don't
send the mistaken signal to the controlled
electrical equipment when it has faults.
The Self-locking Function
If preset the self-locking function, the press
slide stops moving after interception of light
curtain. But the press can not be restart, when
the light curtain is recovered to passing through
state. It shall be restart by pressing the reset
button.
Immunity
For the electromagnetism signal,the intense
lamplight,the welding and surrounding light
source has better immunity.
