DIFFERENTIATION
DESCRIPTION
Honeywell FF5 Series are magnetically actuated, noncontact, pre-wired safety switches for use in machine
guarding applications. These switches are designed to
monitor the position of the guard and provide inputs to
safety relays. The compact rectangular packaged switch
and actuator are available with either an ABS plastic or 316
• Non-contact sensing requires no mechanical linkage to
actuate switch
• Two safety contacts when actuated for inputs to safety
relay
• Auxiliary contact closes when actuator moves out of the
operating range
POTENTIAL APPLICATIONS
With CE and UL certifications, the switches can be installed
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
on machinery for global applications.
PORTFOLIO
VALUE TO CUSTOMERS
Honeywell FF5 Series safety switches are part of a
comprehensive line of Honeywell electromechanical and
non-contact safety switches. For more details on the

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 where
misalignment of the machine guard may occur. Installed
with two M4 or #8 screws, the FF5 Series is sealed to IP67
for wet and dusty environmental applications.
• 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, or
rotation/hinge for flexible installation

Designed for interfacing to safety relays which has low inrush current to the FF5 Series switch contacts.
Sensing distance is front surface of switch to front surface of actuator. When actuated the targets on the surface of the switch and actuator
are designed to align.
