1 / 4 page 3-42 Interlock Switches Non contact Switches Ferrogard 1, 2, 20 & 21 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 FRS1, FRS2, FRS20, FRS21 are rectangular housings. Sealed to IP67 (NEMA6P), these Ferrogards are ideal for wet environments. 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 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. Features • Non contact actuation • High tolerance to misalignment • High switching current (up to 2A AC, 1A DC) • Plastic rectangular housing (IP67) • Cable or Quick Disconnect (QD) connections Specifications Standards EN954-1, ISO13849-1, IEC/EN60204-1, NFPA79, EN1088, ISO14119, ANSI B11.19, AS4024.1 Category Cat. 1 Device per EN954-1 Dual channel interlocks suitable for Cat. 3 or 4 systems Approvals CE marked for all applicable directives and cULus Reed Contacts Safety Auxiliary Operating Distance – Make 12mm (0.47in) 15mm (0.59in) Operating Distance – Break 23mm (0.91in) 26mm (1.02in) Closing Time 3.0ms 0.5ms Dropout Time 2.1ms 0.3ms Bounce Time 0.7ms 0.7ms Initial Contact Resistance 15m Ω 10m Ω Initial Capacitance, Terminal to Terminal 0.65pF 0.2pF Initial Insulation Resistance, Terminal to Terminal 1 x 106 Ω 1 x 106 Ω Safety Contact Switching Capability AC DC 250VAC 2A max 24VDC 1A max Safety Contact External Fusing AC DC <1.6A quick blow <0.8A quick blow Auxiliary Contact Switching Capability 300VDC, 250VAC, 0.5A including inrush 15VA/10W suitable for AC/DC circuits Min Initial Breakdown Voltage 600VAC 600VAC Operating Temperature -10°C to +65°C (14° to 149°F) Enclosure Protection IP67 (NEMA6P) Cable FRS 1 0.75mm2 (18 AWG) 2 wire Jacket OD 5.6mm (0.22in) FRS 2 0.50mm2 (20 AWG) 4 wire Jacket OD 6.5mm (0.26in) FRS 20 0.50mm2 (20 AWG) 4 wire Jacket OD 6.5mm (0.26in) FRS 21 0.50mm2 (20 AWG) 6 wire Jacket OD 7.5mm (0.3in) Quick Disconnects M12 x 1, 4 pin or 6 pin Case Material Red moulded ABS Plastic Mounting Any position M4 mounting security screws included Weight (not including cable) FRS 1 FRS 2 FRS 20 FRS 21 Sensor Actuator 35g (0.08lbs) 85g (0.19lbs) 40g (0.09lbs) 85g (0.19lbs) 43g (0.09lbs) 85g (0.19lbs) 43g (0.09lbs) 85g (0.19lbs) Electrical Life 1 x 106 at the rated load Mechanical Life 10 x 106 Vibration 7g, 10 to 200Hz Shock 50g |
