Safety grating is a kind of safety grating protection device (also known as safety light curtain, safety photoelectric protector, punch protector, infrared safety protection device, etc.) to avoid personnel approaching mobile machinery;
It is mainly used in punches, hydraulic presses, shearing machines, robotic arms, automation equipment, etc., it can be used to replace the traditional mechanical barrier, but also to increase the maintainability of the equipment. The equipment is equipped with a safety light curtain, which can improve the safety of equipment operation.
Safety light curtains.
First, when we want to protect the safety of operators, the safety grating should choose the model of normally closed signal output. For non-personnel safety classes, the grating model with normally open signal output can be selected;
Clause. 2. Select signal output mode: such as NPN or PNP normally open and normally closed, relay, etc.;
Clause. 3. The protection level of the grating is divided into the following three types:
They are 10 mm optical axis spacing to protect fingers or other small objects, optical axis spacing 20 mm to protect the palm or objects larger than 20 mm, optical axis spacing 40 mm to protect wrists or objects greater than 40 mm;
Clause. Fourth, we need to understand the size of the hazardous area covered by the operation of machinery and equipment. It has been used as a reference for selecting how high the grating protection height needs to be and how long the through-beam distance should be.
Clause. 5. Select the safety grating according to the power supply voltage of the equipment;
Clause. 6. Select targeted models according to the use environment of safety gratings, such as anti-light type, waterproof type, etc.
