Demand for Small Devices: How Industry Trends Affect Connectors
By Bob Stanton, Director of Technology, Omnetics
electronic connector systems. New smaller and more portable electronics in aerospace, defense, and other stressful environments, like those encountered in robotics and oil exploration, are resulting in changing demands and designs. To meet the needs, changes are needed

to standard micro-D connectors. New tech- nology, including new latching Micro-D con- nectors developed by Omnetics, offer signifi- cant improvements for rapid connection and release with proven signal integrity for the portable and ruggedized electronics flooding into the market. The new latch technology provides high shock and vibration performance tested at military- level specifications.
Smaller and Lighter It is a fact of life that instru-
ments are changing rapidly and everything is getting smaller. Today’s newer electronic instru- ments can afford neither the space nor the weight required by older cabling and connector systems. Even many of the older mili-
tary specification models are rap- idly becoming outdated in the face of the evolving demand for smaller and lighter connection systems.
Cable types to prevent signal intrusion.
apidly changing demands and designs in product performance and electrical integrity are having a huge effect on
Older connectors like the D-Subminiature connectors (Mil.-DTL-24308), requiring 0.1 in. from pin to pin do not fit within today’s systems. Rapid industry growth in micro-size at 0.05 in. spacing and nano-connectors at 0.025 in. spacing is fulfilling the need in today’s higher technology electronics. The change is sweeping through many
industries as each one in turn sees the bene- fits of rugged portability and miniaturization and adjusts to the need for new connector and cable designs. For example, a number of military and
deep space applications began using robotics and soon we began to see emergency rescue device development companies beginning to use miniature cables and connectors.
Then, since many emergency applica-
tions require the use of devices that can run at higher temperatures, up to 392°F (200°C), we began to see the petroleum research and geothermal industry following suit and test- ing new micro-D connector technology for their applications. In short, squeezing a lot into small
spaces is becoming key across the industry and micro-D connector technology must be available to serve that need. The designers are heralding the ruggedized miniature con- nector as a major solution to a combination of design needs and application-related demands. The trend also includes a need for quick plug-and-release connector technology, because users do not want to have to go back to a lab and use additional tools to mate or release a connector.
Increasing Circuit Complexity As electrical circuit technolo-
gy and complexity evolves, chip speeds are increasing their data processing rates, current and volt- ages are being used at lower levels and mixed signal systems are demanded within the same inter- connect system. The use of these new circuits with higher and high- er circuit speeds are evident near- ly everywhere, but are most criti- cal in surveillance cameras and
