Non-Contact Safety Switches

004746FF5 SeriesIssue 3Datasheet
FEATURES• Non-contact design requires no operating force to actuateswitch• ABS plastic housing or 316 Series stainless steel housing
for switch and actuator• Pre-wired cable length of 3 meters or 10 meters• Compact size of 52 mm x 28 mm x 14 mm[2.0 in x 1.1 in x 0.55 in]• IP67 environmentally sealed switch and actuator• CE and UL 508 certifications

DIFFERENTIATIONDESCRIPTION
Honeywell FF5 Series are magnetically actuated, noncontact, pre-wired safety switches for use in machine
guarding applications. These switches are designed tomonitor the position of the guard and provide inputs tosafety relays. The compact rectangular packaged switch
and actuator are available with either an ABS plastic or 316
Series stainless steel housing. The small housing permits
installation on machinery where there is limited space. A
magnetic actuator is supplied with each switch. The noncontact switch design allows for flexible installations wheremisalignment of the machine guard may occur. Installedwith two M4 or #8 screws, the FF5 Series is sealed to IP67
for wet and dusty environmental applications.
With CE and UL certifications, the switches can be installed• Non-contact sensing requires no mechanical linkage toactuate switch• Two safety contacts when actuated for inputs to safety
relay• Auxiliary contact closes when actuator moves out of theoperating range

POTENTIAL 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 equipmenton machinery for global applications.

PORTFOLIOVALUE TO CUSTOMERSHoneywell FF5 Series safety switches are part of acomprehensive line of Honeywell electromechanical andnon-contact safety switches. For more details on theextensive line of Honeywell safety switches, click here.

• Non-contact sensing minimizes installation and set-up• Pre-wired cable with color coded individual lead wires
simplifies electrical connection• Actuator can approach switch from head-on, slide-by, orrotation/hinge for flexible installation
