Robust Light Curtain

The SF2-EH series of safety light curtains provides Type 4 protection for complete machine safeguarding applications. With a maximum individual sensor height of 1580mm and a 10m detection distance, one sensor can cover the are that previously required 2 sensors. Further expansion can be performed by connecting up to 4 sensors, or 192 beam channels, in series, all with built-in interference support. Parallel connection of up to 12 sets is also possible.

It uses two independent CPUs, which mutually check the safety conditions. High reliability fail-safe design is realized by incorporating dual circuits for signal processing and output. Furthermore, in order to ensure safety, FMEA (Failure Mode & Effects Analysis) has been used to prove safe operation.

The sensor unit continually performs self-checking on its internal circuitry, its cable integrity and even checks for interference from extraneous light. In the event of any fault or malfunction, the sensor outputs the same signal (OFF signal) as is produced during actual beam detection operation.
