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. Max Conductor Size 1 x 2.5mm2 (14 AWG) stranded with sleeve stripped 8mm,1 x 4mm2 (14AWG) solid conductor Terminals The absence of moving parts and direct physical contact between sensor and actuator eliminate mechanical wear.

However, risks should be thoroughly evaluated prior to application of this method. Material & Colour Red polycarbonate 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.

M Interlock Switches Non contact Switches Ferrocode 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 Application Details Actuator Spacing Actuator Approach Directions >25mm Switch Switch Actuator Actuator 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. Wigan WN2 4HR 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.
