SPECIFICATIONS
Light curtain common specifications
Notes: 1) Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of +20 °C +68 °F.
2) Regarding EU Machinery Directive, a Notified Body, TU
••
V SU
••
D, has certified with the type examination certificate.
3) The product has been safety-certified in accordance with UL, ANSI, CSA, and other standards by TU
••
V SU
••
D, a nationally recognized safety laboratory
(NRTL) that has been approved by the Occupational Safety and Health Administration (OSHA) as defined by 29 CFR 1910.7
4) The operating range is the possible setting distance between the emitter and the receiver.
5) In case the blanking function is valid, the operation mode is changed. For details, refer to “Safety distance” (p.22)
6) During muting, control output will not turn off even if the beams are interrupted.
7) When the blanking function is enabled, the operating mode will change.
8) The manual reset and automatic reset are possible to be switched depending on the wiring status.
9) In case of using optional function, the handy-controller SFB-HC is required.
10) Do not use or store the device in an environment where the air pressure is higher than the atmospheric pressure at an altitude of 0 meters.
