Technical Information<br />
Material and Surface Treatments<br />
The standard <strong>Fischer</strong> <strong>Connectors</strong> shells are nickel plated brass with natural (silver) chrome finish. Black chrome<br />
finish is available as an option; see Options pages 4-10 and 6-10. Internal piece parts are nickel plated brass.<br />
When warranted by an extreme environment, in most cases stainless steel can be substituted for all metal parts.<br />

Insulator and Sealing<br />
Contact blocks and other insulators for our standard connectors are manufactured from high performance<br />
engineering plastic materials. The standard materials of each connector series are listed under Electrical &<br />
Contact Specifications in Section 4 through 10. Ceramics and other dielectrics are available on special order.<br />

Sealed connectors are fitted with O-rings and cable sealing gaskets. The standard materials are:<br />
■ Viton ® for O-rings<br />
■ TPE (Thermoplastic Elastomers) for cable seals, protective sleeves and strain reliefs.<br />
SAE-AMS2460<br />
Please note that as an elastomer reaches its lower temperature limit, it becomes rigid and loses the flexibility<br />
required for connector mating and unmating. If sealed connectors have to be manipulated at low temperatures,<br />
the O-rings in the mating area has to be of a material with a considerably lower temperature limit.<br />
The elastomers listed below represent presently available materials, which <strong>Fischer</strong> can substitute when required<br />
by an application. Not all materials are available in all shapes and sizes so please check with us for details.<br />
