IMPROPER INSTALLATION
• Consult with US and/or European safety agencies and
their requirements when designing a machine control,
interface and all control elements that affect safety.
• Strictly adhere to all installation instructions.
Failure to comply with these instructions could result
in death or serious injury.
PRODUCT DESCRIPTION
The FF-SNC Honeywell safety non contact switch is a tamper
resistant safety system for monitoring machine guards. The
actuator being a passive component, the safety switch is the only
component that needs to be wired to the control unit and cannot be
defeated by a regular magnet.
Each system is made up of one or several safety switches,
actuators and a control unit. The Honeywell FF-SNC safety non
contact switches are designed in compliance with the requirements
of the EN 954-1 European Standard for Category 3 Protective
Devices.
The FF-SNC is especially suited for applications where perfect door
alignment can not be attained. The FF-SNC Series can be
mounted on sliding, hinged or removable machine guards. The
output of the control unit is triggered as soon as the distance
between the safety switch and the actuator is greater or equal to
8 mm/0.32 in. This switching distance compensates for the
machine vibration or a minor issue with the installation alignment.
The sensor and actuator small size makes it usable under tight
space requirements. The safety switches and the actuators provide
excellent chemical and mechanical resistance. Stainless steel
housing versions fulfil the requirements of the Food and Beverage
industry.
The FF-SNC400 safety control unit comes in a 75 mm / 2.95 in
package and can monitor up to 4 sensors.
The FF-SNC200 safety control unit with its 22,5 mm / 0.89 in width
will easily find a place in the electrical cabinet and can monitor
2 sensors. Both control units can be placed up to 100 m / 328 ft
away from the safety non contact switches. The indicators located
on the front cover of both control units provide individual door status
information.
The FF-SNC1EXT extension module can be added to the
FF-SNC400 or FF-SNC200 control unit and allows the
connection of 5 additional sensors.
