Issue 4Datasheet
FEATURES• Non-contact design requires no operating force to actuateswitch• ABS plastic housing for switch and actuator• Green LED on switch for guard status indication• Slim package size: 19,0 mm x 19,0 mm x 82,5 mm[0.75 in x 0.75 in x 3.25 in]• Choice of 1 NC/1 NO or 2 NC contacts• Pre-wired cable length of 3 meters or 10 meters or an
integral Micro AC ½ in - 20 quick disconnect• IP67 environmentally sealed switch and actuator• CE and UL 508 Certifications

DESCRIPTION
Honeywell FFS Series switches are coded magneticallyactuated non-contact safety limit switches for use inmachine guarding applications. The FFS Series of switches
are designed to monitor the position of a guard for a safetyrelated system. For ease of operation, a green LED is integral
to the switch and turns on when the switch senses theDIFFERENTIATION• Non-contact sensing requires no mechanical linkage toactuate the FFS Series switch• Integral green LED provides status of NC switch contacts• Up to two safety contacts when actuated for inputs tosafety circuit• Optional auxiliary contact closes when actuator moves outof the operating range

actuator. The rectangular design of the switch and actuatorcan be beneficial where a slim package size is desired. APOTENTIAL APPLICATIONS

magnetic actuator is supplied with each switch. The switch

installed on machinery for global applications.

Equipment and machinery guards• Can forming and filling (aluminum, plastic, and steel)• Packaging equipment• Pick and place assembly equipment• Plastic molding equipment• Printing machinery• Semiconductor equipment• Textile machinery• Woodworking equipment

VALUE TO CUSTOMERSPORTFOLIOand actuator are each installed with two M4 or #8 mounting
hardware. The non-contact switch design allows for flexible
installations where misalignment of the machine guard may
occur. The switch and actuator are sealed to IP67 for wet
and dusty environmental applications.
With CE and UL certifications, these switches can be• Non-contact sensing minimizes installation and set-up• Pre-wired cable with color-coded individual lead-wire orintegral Micro AC ½ in - 20 quick disconnect connector
simplifies electrical connection• Actuator can approach switch from head-on, slide-by, or
rotation/hinge for flexible installation

Honeywell offers a wide range of FF Series magneticallyactuated non-contact switches as well as other noninterlocking safety switches which include the GSS Series
electromechanical limit switches and the cable/rope pullswitches (1CPS Series single head and 2CPS Series dualhead). Honeywell safety interlocking switches include themetal housing EN50041 GK Series, metal housing solenoid(trapped key) GKL/R Series, miniature plastic housing GKM
Series, EN50047 plastic housing GKE Series, and plastic
housing GKN Series.
