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.
>>Precautions for use
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.

Cautions For Use
- Do not utilize this safety light curtain in “PSDI Mode”, in which the safety light curtain is utilized as an activator for machinery.
- To use this product in the U.S.A., refer to OSHA 1910. 212 and OSHA 1910. 217 for installation, and in Europe, refer to EN ISO 13855 as well. Observe your national and local requirements before installing this product.
- This website is a guide to select a suitable product. Be sure to read the instruction manual prior to its use.
Cautions for explosion-protection
- This device has a flameproof structure and explosionproof performance that can only be ensured when the product meets all of the specified conditions and specifications. Failure to observe any of them will result in the loss of the explosionproof performance.
- Use flameproof electric appliances that are compatible with hazardous locations (locations where an explosive atmosphere of gas or vapor may exist).
- Make sure that the power supply is off while wiring. Otherwise, electric shock may result.
- Never modify or repair the product yourself. Failure to follow this instruction may result in an explosion or ignition.
- Protect the cables, or external conductors, against possible external damage by passing them through a sufficiently strong metallic tube or by other means.
- Ground the grounding terminal without fail. Failure to follow this instruction may result in an explosion or ignition.
- Do not open the lid of the flameproof enclosure, and do not remove the window frame fixtures of the enclosure. Failure to follow this instruction may result in an explosion or ignition.
- The product can be used in the areas where flameproof appliances of “Groups IIA and IIB” and temperature classification “T1 to T6” can be used, and where explosive gases may exist.
Japan: Zone 1 and Zone 2
Europe: Zone 1 and Zone 2 (Category 2G: ATEX)

Mounting
- When mounting the safety light curtain, secure it in place using four M10 bolts.
- The cable lead-in port is threaded for wiring protective tube or conduit (NPT 1/2). Using a steel wire tube etc., if necessary, screw a tube into the port at least five complete threads.
- After beam alignment, tighten the hexagon-socket-head bolts for adjusting mounting angle for fixing. The recommended tightening torque is 1.5 to 1.7 N·m. (The hexagon-socket-head bolts for adjusting mounting angle are on top and bottom surfaces of the emitter and receiver.)
Grounding
- Ground the external grounding terminal on the flameproof enclosure to keep the grounding resistance at or below 100 Ω.
- For grounding, use an electric wire with equivalent or higher insulation performance to a 600 V polyvinyl-insulated electric wire, and of a thickness ensuring safe carrying of the expected maximum ground current.
Others
- This device has been developed / produced for industrial use only.
- Use the device according to the specifications of this product. Failure to follow this instruction may result in electric shock, injuries, or damage to the product.
- Unpack the product with the right side facing up. If you do not follow this instruction, you may get injured.
- Do not touch any terminals when measuring the insulation resistance.
Failure to follow this instruction may result in electric shock. - If there is something abnormal with the product, immediately turn OFF the product. Otherwise, electric shock, injuries, or a fire may result.
- Before measuring the insulation resistance, confirm that there is no explosive atmosphere of gases or vapor around. Failure to follow this instruction may result in an explosion or ignition.
