Product overview:
NA2 series safety light curtain is a compact and solid ultra broad safety light curtain without blind area. It emits light from the front, with a cross-sectional area of 30 * 13mm, a maximum protection distance of 3m 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 (customized when ordering).
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 equipment
■Fixture equipment
■Automated storage system
■Welding equipment
■Packaging equipment
■Regional protection
■Test equipment
■Food machinery
■Electronic equipment industry
■Hot press molding machine industry
■Pharmaceutical equipment industry
■Robot manufacturing line
