WHY IS THE L.S.A. SYSTEM SUPERIOR?

The primary function of connector contact is electrical

conductivity. Also, a mechanical function is required to

provide normal force between male and female contacts.

In order to provide for proper mechanical characteris-

tics, material that has good memory or “elasticity” must be

chosen. This will ensure contact normal force in a coupled

condition and allow for repeated coupling and uncoupling.

Unfortunately, many materials that have good mem-

ory characteristics have low electrical conductivity. For

instance, beryllium copper is a good choice for mechani-

cal function; however, some beryllium copper alloys are

poor conductors and have relatively low conductivity

rates.

The conductivity path of many contact designs

goes directly through materials that have been cho-

sen based on mechanical need. If these materials have

a low conductivity rating, increased contact resistance

will result.

Positronic Large Surface Area Contact System

separates the mechanical and electrical functions. A

spring retention member provides normal forces, while

the electrical conductivity path is through highly conduc-

tive contact material. See above detail.
