F3SN-A Safety Light Curtain

Highest Level Safety Design Prevents Mechanical Accidents

Safety Design Backed by Technology

Pursuing safety with the highest level of safety design and FMEA

We pursued the safety of F3SN-A to the limit with the mutual check of two CPUs, safe design by dual circuits of signal control and output, and FMEA*, which verifies the safety of the operations.
*FMEA : Failure Mode & Effects Analysis

Conforms to Global Safety Standards for Safety Sensors

Type 4 Level Sensor Specified by IEC and EN Standards

Conforms to the now mandatory international standards for safety sensors: IEC61496-1, IEC61496-2, and EN61496-1. The F3SN-A/ F3SH-A are type 4 Sensors meeting the highest safety standards of category 4.

Certification for United States and Canada from UL in the United States

Can be used with machinery designed for OSHA regulation and ANSI standards.
Certified for UL Listing based on UL508, IEC61496-1, and IEC61496-2 and UL Listing for Canadian safety standards. Can be used with machinery that will be used under OSHA regulations (29 CFR 1910.212), which are stipulated under the Occupational Safety and Health Act of 1970. Also fulfills the requirements for ANSI/RIA R15.06-1999, the United States Safety Requirements for Industrial Robots and Robots Systems. The F3SN-A/ F3SH-A can be confidently used with machinery and equipment bound for the United States and Canada.

Connect up to 3 sets in series. Prevents mutual interference.

Up to 3 sets can be connected in series by using both the standard model and a series-connection model with a connector. You can create a 3-set system by just wiring one set - no need to wire three sets separately as was required with earlier models. This facilitates protection for all dangerous machine and device surfaces. Mutual interference is also prevented.

Setting Console

All Functions Can be Set Easily and Safely

Easy Function Settings, Monitoring, and Copying to Multiple Sensors
In earlier Sensor models, function settings were made using an internal DIP switch, and switch operation used to be very difficult after Sensor was mounted. That's why we added a Setting Console.
Just connect the Sensor Cable when it is time to make the function settings and you can easily make blanking and all other settings directly from the Setting Console.

Password Protection 
Prevents inadvertent changes to settings

Two Types of Blanking Functions

Blanking functions changes the Safety Light Curtain detection patterns

Basic Pattern 1 : Floating Blanking

Disables detection for 1, 2, or 3, non-specific beams. Output is turned OFF if more than the specified number of beams are obstructed. Ideal for applications where a robot arm for removing workpieces passes through the Safety Light Curtain detection zone at irregular intervals.

Basic Pattern 2 : Fixed Blanking

Uses a teaching technique to mask and disable specific beams. Ideal for application where part of a machine or jig is always inside the fixed detection zone of the Safety Light Curtain.
