The "MW" series is the foundation of all the variations shown on the following pages. A heavy duty double crimp connects lead wires to solid nickel pins. Connections are insulated with sleeving. Maximum temperature at the lead area is 400 F/200 C. Standard lead length is 12". Specify additional length. The "MW" is the standard design for all diameters (except 1/8").

FIG. X HIGH TEMPERATURE FULLY FLEXIBLE LEADS

The Fig. X modification is high temperature, fiberglass braided, mica tape insulated lead wires internally connected and swaged in place. Fully flexible from the exit of the sheath, the high temperature (850 F/450 C) lead wires are ideal for applications where spacing is limited and flexing occurs. On the Fig. X Mighty Watt Plus, the modification adds 1/4" to the sheath length of stock items. 12" leads are standard specify additional length. * At lead end. Standard cold sections can be increased. Consult Ogden for metric diameter dimensions. Fig. X Flexible Leads Dia.

Stainless steel armor cable is the best protection for use where lead wires experience abrasion. See chart below for the additional dimension the Mighty Watt Plus Figure A and D add to the sheath length of stock items. When ordering non-stock Fig. A and Fig. D items, specify the overall sheath length. 14" high temperature (850 F/450 C) leads with 12" cable is standard specify additional length. * At lead end.
