Capacity, capability, and packing are essential elements of racecar subsystems. Now, connector specialist Souriau has launched a new, harsh environment connector that packages 43 contacts within a size 12 shell. Revealed at the UK’s Autosport International show, it is described by the company as being the market’s highest density connector, designed to provide a lightweight solution to connecting power and signal lines within space-critical areas.
The rugged connector provides almost twice the number of contacts of a size 12-35 and is two shell sizes smaller than a partially populated size 16-35 with 55 cavities, according to Souriau, adding that it provides the same level of reliability and robustness as the standard 8STA range.
"With long-term performance and reliability being such a crucial customer requirement, we’ve developed a special contact retention mechanism to ensure the connector withstands the most severe vibrations of a race or rally throughout its service life," said Souriau’s Business Development Manager, Mark Richardson. "The new High Density’s clear cavity numbering, and the ease in which the contact can be inserted and extracted, simplifies assembly and servicing. With the direction of loading clearly marked, connectors can be more quickly and accurately populated, avoiding error, the need for rework, and reducing inspection time."
User friendliness was a particular design criterion of the 8STA to allow engineers to easily load contacts at the first attempt without the need for a tool. A special clip mechanism signals to the cable harness technician that the contact is in place.
The connector has an oval flange receptacle for front or rear mounting and can be supplied with integrated mounting nuts, avoiding the need for nut plates. The gold-plated contacts are suitable for cable sizes from 10 to 35 mm² (0.016 to 0.05 in²). The temperature range for the 8STA is -55° to +175°C (-67° to +347°F) and it can support 200 A at ambient temperatures.
Souriau products are engineered and manufactured in the U.S., Dominican Republic, Europe, Morocco, India, and Japan. The group employs 2200 people worldwide and has a sales turnover of more than 235 million.
