Product overview:
SZG series safety light curtain is a compact and solid ultra-thin safety light curtain with no blind area design, with a cross-sectional area of 16 * 30MM, a maximum protection distance of 2M and a maximum height of 3M. It has strong anti-interference ability and can be used normally next to the 23KW power of the frequency converter. Through frequency conversion technology, dense installation will not interfere with each other. Output signals include NPN, PNP and relay.
It has floating or fixed addiction elimination function.
Description of blanking function: a certain number of lamp beads can be set before leaving the factory. These lamp beads can be anywhere or fixed. It is suitable for occasions where there is something blocking the protective surface. This function needs to be explained when ordering. It is not available at the factory by default.
Typical application areas include:
■ Machine tool industry
■ Pressure machine
■ Automobile manufacturing line
■ Fixture equipment
■Logistics automatic three-dimensional storage system
■ Welding equipment
■ Automatic packaging equipment
■ Regional protection
■ Test equipment
■ Food manufacturing
■ Electronic equipment industry
■ Hot press molding machine industry
■ Pharmaceutical equipment industry
■ Robot manufacturing industry
