SUNX SF4-AH series description:
Basic, compact, type 4 light curtain

Small Light CurtainThe SF4-AH series has surpassed the most stringent international safety levels and is compliant with the machinery directive and OSHA/ ANSI standards. This series has been certified for usage in any workplace around the world.

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

The SF4-AH has a high-speed 11 ms response time, regardless of the number of beam channels. This high-speed response simplifies the entire process of safety distance calculation and allows the safe distance between the danger areas and the light curtain to be reduced.

Beam alignment has been simplified due to a convenient 4-bar LED display that indicates partial and full alignment. A laser alignment tool is also available for use in long distance set-up.

Also incorporated into the SF4-AH is the ELCA, or Extraneous Light Check & Avoid function. This is an advanced interference prevention system that not only cancels the effect of high intensity extraneous light but also avoids mutual interference with other units by shifting the scan timing of the light curtain.

Up to three sets of curtains can be connected in series, thus reducing the number of safety relay units needed for a single machine. This is significant for reducing the costs of machine safeguarding.

Fixed and floating blanking functions are also built-in to the light curtain. All blanking functions are easily configured using the SF-HC Handy Controller. In addition, the SF-HC can also control the light emission intensity, password protect against unauthorized changes, and easily copy settings to other light curtains.

The SF-AC safety relay unit is available for safety applications with a built-in power supply. With a 10ms response time and removable terminal blocks, the SF-AC ensures safe and stable protection for your machines.
