Flameproof Type Safety Light Curtain Type 4 BSF4-AH80
Features
■ For your safety
In using the safety light curtain, please establish a control system to satisfy the below items in order to ensure safety with a total system.
Complies with worldwide flameproof standards
The safety light curtain is built into a highly flameproof enclosure conforming to the IEC 61496 (Type 4).
The safety light curtain can be safely used in any workplace throughout the world where flameproof performance is required.
Europe : Complies with flameproof structures (Ex db [op is] IIB T6 Gb) specified by EN 60079-0, EN 60079-1, EN 60079-28 and ATEX Directives (2014/34/EU).
United States : Complies with flameproof structures (Class I, Zone 1, AEx d IIB T6) specified by FM Class 3600, ANSI/ISA-12.00.01, ANSI/ISA-12.22.01.
Canada : Complies with flameproof structures (Ex d IIB T6) specified by CAN/CSA E60079-0, CAN/CSA E60079-1.
China : Complies with flameproof structures (Ex d IIB T6 China Gb) specified by GB 3836.1, GB 3836.2
Japan : Complies with flameproof structures (Ex d IIB T6) according to technical standards conforming to IEC Standard 79.
Hazardous locations: Zone 1 location, Zone 2 location
Classification of gas or vapor, and Temperature classification:IIB T6
Ample protective height 1,595 mm 62.795 in
A single safety light curtain is sufficient for production lines with high working heights such as vehicle body spray-painting lines.
Mounting bracket enables easy beam-axis alignment
The beam-axis alignment is easy since angle adjustment is possible with the enclosed rear mounting bracket.
Less operating errors from extraneous light interference
A double-scanning method and retry processing are some unique new technology that help to avoid momentary interference from extraneous light coming from nearby equipment. A reduction in operating errors resulting from extraneous light interference can mean less frequent machinery stoppages and reduces the amount of time that a production line is not running.
Mutual interference is reduced without the need for interference prevention lines
No interference prevention lines are required between different items of equipment, so that safety light curtains can be installed with greater flexibility.
