Interlock Switches
Non contact Switches
Ferrocode
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.
Features
• Electro-magnetic tamper resistant coding
• Interfaces directly to a safety relay control unit
