Coil should not be pulsed with less than the nominal coil voltage and pulse width should be a minimum of three times the specified operate time of the relay. If these conditions are not followed, it is possible for the relay to in be the magnetically neutral position . 2.Switching voltage is for test purpose only and are no to be used as design criteria. 19.2 0.756 0.7 5 0.027 0.197 40 1.575 47.5max. 1.870max. 4.9~10 9.8~20 19.7~40 13 0.512 <4.8 <9.6 <19.2 3(-) 6.16 0.243 2 8 2 32 2 130 1.5 0.059 6 12 24 45 1.772 36.1 1.441 006-4500 012-4500 024-4500 3 5 0.197 4(+) 4 2(-) 2(+) Wiring diagram Mounting (Bottom view) NOTES 1).Dimensions are in millimeters. 2).Inch equivalents are given for general information only. 3).Relays shall have plus(+) or plus(+) and minus(-) signs placed on the circuit diagram as shown.
