Feature
■ Applicable to the safety protection against dangerous mechanical appliances such as forging press,punch,welding
machine, clipper, and die-casting machine, etc., and can reliably protect person and goods safety,and also the materials
circulation line, assembly line, and auto-control devices signal collection
■ Conform to Security Level 2 of IEC61496-1/2 standard, namely, it s a self-testing, disorderly closedown, and non-contact
type protection device
■ Smart figure, width and thickness only 30mm, can save installation space effectively; the equipment connect with cables
through air plug and socket, can be assembled & unassembled, and wiring correctly, quickly, and conveniently
■ Adopt integration design, can directly connect with equipment
■ Adopt latest microprocess, ASIC, and SMT technology
■ 2 sets of detection and control loops inside, more safe and reliable
■ Red, Yellow, Green, 3-color indicator light, with built-in buzzer, users can detect the possible malfunction ( for example,
the connecting joint loosen, etc.) correctly, directly, and quickly, convenient for fast and accurate settlement
■ Self-adapting & regulating design inside, no blind area, detect distance from very zero
■ Wirelesscommunicationisadoptedbetweenprojectorandreceiver. Anyformofcable-connectingisunnecessary.
■ It’s more safe, convenient and reliable
■ Output NPN & PNP at the same time, and can external hang relays directly to meet the needs of different use
■ Wide choice of resolution ratio and protection breadth, can be custom-made to meet customers special needs Replaceable
with similar products made by Honevwell, Sti, SICK, BANNER, SUNX, KEYENCE, OMRON, etc. |

Installation
Figures of installation and lead-connection:
Lead instruction
GA optic screen installation
Directly connected to PLC or PC
Firstly, connect the brown lead (DF12-24V), green lead (0V) of both projector and receiver to DC power supply; then, butt connecting the blue lead (SYNC); finally, connect the white lead or black lead (signal-output lead) to the signal-input terminal of PLC or PC.
Directly connected to load
NPN output PNP output
Connection
■ Connect the leads of projector and receiver through aviation connector (note: the leads of projector are three-wire
system: brown, blue, green; while the leads of receiver are five-wire system: brown, green, blue, black, white.)
■ Connect the brown leads to power supply’s anode and green leads to cathode; butt connecting blue leads; connect black
lead to NPN input terminal of controller and white lead to PNP input terminal, or directly connect black lead and whit lead to
relay( if relay has polar requirement, connect white lead to anode and black lead to cathode).
■ According to your demand, you could select the output form, either NPN output or PNP output, and then cut off the other
lead or insulate it in case of any inconvenience.
Connected with optic screen controller
