Description
A two-channel system, the Ferrocode setup consists of an actuator
and a separate safety switch head that is connected to a monitoring
control unit. The Ferrocode uses electromagnetic coding, which
provides a higher level of security over magnetic coding systems. To
further prevent possible override of the system, both sensor and
actuator are supplied with tamper-resistant mounting hardware.
The absence of moving parts and direct physical contact between
sensor and actuator eliminate mechanical wear.
A Ferrocode sensor may be used without the control unit for low
power/low risk applications. However, risks should be thoroughly
evaluated prior to application of this method.
The control unit should be used when monitoring and checking of
the circuit is required. Up to 6 Ferrocode switches can be interfaced
with the 110/230V control unit and up to 15 Ferrocode switches
with the 24V version. A control unit may also be used in conjunction
with electromechanical safety devices such as limit switches, gate
interlocks and emergency stops with two contacts, 1 N.O. & 1 N.C.

Typical Application Details
On presenting the actuator to the
switch, the high-intensity
electromagnetic field together with a
resonant frequency signal causes the
contacts to close. On removing the
actuator (opening the door) the safety
contacts open, isolating the machine.
The switch can not be overridden by
magnets, tools, etc.
Safety contact operating distance:
make 7mm, break 9mm
Auxiliary contact operating distance:
make 9mm, break 14mm

On hinged doors, install switch at the opening edge.
Where 2 switches are mounted adjacent, they should
be no closer than 25mm. Recommend a 2mm spacing
between switch and actuator.
Typical Configurations
The Ferrocode switch can
be used without a control
unit for low risk/low power
applications.
Six Ferrocode switches can be used with one control
unit for high risk applications. Connect the N.C.
contacts (black and white wires) in series and the N.O.
contacts (green and yellow wires) in parallel.
One Ferrocode switch
used with a control unit
provides a higher
integrity system.
