Special Contacts for DIN, ERmet and D-Sub Connectors Special high current and coaxial contacts are designed for use mainly in so called mixed connectors, where those contacts can be loaded by „snap in“ means and are used besides an amount of signal contacts dependend on the connector style. Mixed connectors are available in DIN, ERmet and D-Sub styles. Look for the letters MD (Male DIN) / FD (Female DIN) / ME (Male ERmet) / FE (Female ERmet) / TMC M (D-Sub Male) or TMC F (D-Sub Female) on our special contact customer drawing. Those letters are defining the mixed connector in which the special contact can be used.

Insulation coordination according to IEC 60664-1 has to be regarded for the complete electrical device. Therefore, the maximum creepage and clearance distances of the mated connectors are specified for consideration as a part of the whole current path. In practice, reductions in creepage or clearance distances may occur due to the conductive pattern of the printed board or the wiring used, and have to be taken into account separately. As a result the creepage and clearance distances for the application may be reduced compared to those of the connector. depends on connector housing when used in mixed connectors <10 mΩ (inner conductor) <3 mΩ (outer conductor) depends on connector housing when used in mixed connectors <10 mΩ 1 -55/125/56 -55/125 °C see drawing of special contact - Coaxial Contacts for use in mixed connectors the applicable value of the connector housing material is valid for use in mixed connectors the applicable value of the connector housing material is valid Class 1: ≥500 mating cycles Class 1: ≥500 mating cycles <10 N / ≥1.6 N Edition 1 <10 N www.erni.com 1 Special Contacts for DIN, ERmet and D-Sub Connectors Number of Pins Process-conditions Solder temperature max.
