FF-ST4B08DM2 - 

The FF-ST4 Series is designed for hazardous point-of-operation or access detection in industrial machine safeguarding applications. Its enhanced output stage design provides longer cable length through M12 plugs (Micro-change type). The Honeywell patented push-pull type OSSD outputs allow for low impedance at any time, while regular open-collector type OSSD outputs have high impedance when OFF. As a result, the M12 limited wire section is no longer a constraint. ASIC technology provides fast response times compared to the micro-processor technology commonly used for safety light curtains. The FF-ST4 light curtain response times are worst-case response times including the sensor and the output stage, the embedded functions processing such as blanking or muting and possible OSSD output failure modes. Fast response times contribute to shortened safety distances and reduced overall machine size. Some models offer flexible configuration of different mode of operations through the M12, 8-pole plug. The Honeywell patented inputs with automatic polarity recognition reduce the amount of wiring and increase the number of configurations while keeping the advantages of the pre-wired, off-the-shelf M12 cord sets. The sturdy metal housing (including zamak end caps), and a small window that reduces exposure to the environment, allow the FFST4 to operate in most harsh duty applications. Accessories include mounting kits, corner mirrors, posts, connectors and interface modules.
