Enclosures, Cabling & Connectors
The series TMC subminiature connectors and high-performance multipin, two-piece connectors are available in five standard sizes to accommodate 9, 15, 25, 37 or 50 contacts. They comply with MIL-C-24308 AND CCTU 08-14.
As these connectors are used in all branches of the electronic and electro-mechanical industries, they are offered with solder wire wrap or press-in terminations. Straight and right-angled dip-solder terminations are available for direct mounting (onto) printed circuit boards.
Each connector consists of a male part (P) and female part (S). On the mating side the connector is equipped with the familiar trapezoidal protective collar to provide mechanical protection against any twisting or unintentional touching of the contact elements.
The contacts are gold-plated in the contact area. The terminations may either be gold-plated or tin-plated. The connection method may be for wrapping - solder (manual and dip solder) - solderless press-fit connections.
A particular characteristic of Erni connectors is the high degree of contact reliability that is achieved through the special design of the contact elements, resulting in low (and constant) contact resistance. In respect of resistance to vibration, the manufacturer has found no evidence of resonance effects on the female elements. The reliability of the contacts is high, even when presented with severe shock and vibration.
Tapered entries ensure easy and reliable entry of the male contact pins into the female counterparts. For special applications (rack mounting) 'float-mounting' - connectors are available. Erni cable housings (hoods) with screw lock slide or latches complement the range.
