INTRODUCTION

The Microtech Line meets the need for ultraminiature high reliability connectors and cables that can be assembled simply and rapidly. This success stems from a new concept in which the cables have been designed in combination with the connectors to achieve the optimum in miniaturization. This same design concept makes possible special features and factory preassembled parts that assures the user of unbelievably simple, rapid and economical assembly. The coaxial connectors require only a single operation to attach the connector and cable. The cable is dressed, inserted into the body and merely screwed into place, thereby resulting in tremendous savings for tooling and labor costs. With optional crimping, the separation force between the cable and connector approaches the average breaking strength of the shield. The multi-pin connectors and correspondingly simple to assemble, with a minimum of loose parts and minimum of operations to perform.
