| Interlock Switches Non contact Switches Ferrogard GD2 Specifications Standards EN954-1, ISO13849-1, IEC/EN60204-1, NFPA79, EN1088, ISO14119, ANSI B11.19, AS4024.1 Cat. 1 Device per EN954-1 Dual channel interlocks suitable for Cat. 3 or 4 systems CE marked for all applicable directives and cULus Safety Auxiliary 12mm (0.47in) 15mm (0.59in) 23mm (0.91in) 26mm (1.02in) 3.0ms 0.5ms 2.1ms 0.3ms 0.7ms 0.7ms 15m 10m 0.65pF 0.2pF 1x106 1x106 Category Approvals Reed Contacts Operating Distance - Make Operating Distance - Break Closing Time Dropout Time Bounce Time Initial Contact Resistance Initial Capacitance, Terminal to Terminal Initial Insulation Resistance, Terminal to Terminal Safety Contact Switching Capability Description The Ferrogard range of magnetically actuated safety switches offers Non contact reliability together with tolerance to misalignment. They are designed to be installed so that when a guard door is opened, the action of the magnetic actuator being removed from the switch opens the N.C. safety contacts which are intended for the isolation of control power to a machine primary control element. The GD2 version has a stainless steel housing for added protection against inadvertent impacts to the housing. The contacts are completely sealed to meet IP68 (NEMA6P) requirements, making them ideal for wet environments. The GD2 also has a wider temperature range than the plastic Ferrogard switches, making them useful in a wider range of applications. Unlike some magnetic switches, the Ferrogards have protected safety contacts to help ensure that they do not fail to danger. In addition, some versions have independent auxiliary signal contacts to indicate the machine and guard condition. All Ferrogards have internal non-resettable overload protection on the safety contact. They should be protected by an external fuse rated as shown in the specifications table.
