SF2B series helps to make safety measures easier and plays an indispensable part in creating a safe working environment. In addition to compliance with the IEC 61496 (Type 2) international safety standard, excellent performance with good ease of use is provided in a wide variety of applications from compact machinery installed side-by-side to save space, through to large equipment for long-range, wide-area sensing.

Two types are available for different minimum sensing object sizes. Furthermore, sub-sensors for serial connection (optional) can be used to connect up to three sets of light curtains (up to a total maximum of 128 beam channels; however the SF2B-A allows up to 96 beam channels when two sets are connected, and up to 64 beam channels when three sets are connected).

Internal unit The inner unit is protected by a cylindri-cal inner case. The seams such as unit and lens surfaces have been greatly reduced, so that particles such as oil mists and dust are prevented from getting in.[The protective structure is IP65 (IEC).] Inner caseProtective caseEnd unit > m The photograph shows a cut-away model.

The system constantly checks the light curtain for problems such as incorrect cable wiring, disconnection and short-circuits, and also for internal circuit problems and incoming light problems. If a problem should occur, details of the error appear on the digital display. The error details can be checked at a glance without the inconvenience of the previous method of counting the number of LED blinks, so that smooth support is possible if problems occur at startup and during maintenance operations, even if assistance is given via telephone. > Normal operation Breaking out error > Digital...

New concept Adapter cables and adapter mountin brackets are available to make it much easier to replace the wiring when changing over from SF2-A series or SF2-N series light curtains or NA40 series or SF1-N series area sensors to a new series (Note). Mounting holes and control circuit connector cables do not need to be changed. There is no need to use spare parts for previous models, so registration numbers can be reduced to SF2B series components only. > Note: For details, please contact our office.
