Hermetic connectors are designed to prevent ingress of air, gases and other liquids into the vacuum-sealed connector in extremely harsh environments. In testing, these connectors should show no detectable gas or fluid leakage. They should be able to withstand high pressures of 10,000 psi or more, ensuring a stable pressure differential on both sides of […]
Why do connectors fail?
Ideally, your connectors perform to their rated lifecycles. If you install a connector rated for 10,000 mating cycles, you expect it to go that distance. But if you’ve ever had a cell phone charger stop working correctly, you know that’s not always the case. And for industrial machinery, improper designs and other factors can cause […]
What are micro-D connectors?
Micro-D connectors are about half the size of D-sub connectors. Both are shaped like the letter D. The early D-shaped connectors were first used in computers because of their compact design. Offering reliable and secure electrical connections, they feature at least two rows of parallel pins and offer high density in a miniature design. The […]
Selecting the correct spring-loaded connector for modern interconnect applications
Spring-loaded connectors are available in multiple high-quality precision-machined solutions to give designers extensive choice. Stephen Capitelli, Manager of Product Engineering, Mill-Max Mfg. Corp. Connectivity is crucial in modern design. The availability of highly reliable and proven connector technologies that facilitate miniaturization and connectivity make a significant contribution to the growth of modern portable devices and […]
What are nanominiature or Nano-D connectors?
Nanominiature or nano-D connectors are offered as both rectangular and circular high-density assemblies. Most of these tiny interconnects use twist pin contact technology to provide a reliable connection even in harsh conditions that encounter shock and vibration, all with low separation force and engagement. Those manufactured by Ulti-Mate use a stamped and formed contact system […]
What does the coding mean on M12 connectors?
M12 connectors are circular connectors with a 12-mm locking thread used for sensors, actuators, Fieldbus and industrial Ethernet, primarily in factory automation applications. Often with ratings ofIP65, IP68 and IP69K, they are ideal for washdown and corrosive environments. They are available with 3, 4, 5, 8 and 12 pins. While higher pin counts are not planned, […]
Behind TE Connectivity’s new Sliver internal cabled interconnects
Last month, TE Connectivity launched one of its thinnest assemblies for speeds of 25 Gbps (and even possibly 50 Gbps) with its new Sliver internal cabled interconnects. Offering a flexible design for making internal input/output (I/O) connections on the board, TE said this new technology simplifies design and helps lower overall costs by eliminating the […]
What are nailhead pin interconnects?
Sometimes the simplest solutions are the best. I can’t describe how many times I sat across from an engineer describing his exotic approach to an interconnect challenge, only to show him that there is a much simpler, easier and cost effective approach to achieving the same result. It’s not the fault of the engineer, he […]
How does height impact socket receptacle selection?
Many, many moons ago, as a young PCB designer, I remember my boss yelling at me to hurry up with my design. He kept barking “don’t worry about the connector, we’ll deal with it later, just put a ‘keep out’ area in that location and run the signals to dummy IO points.” There were so […]
What are the most common and cost-effective pin retention designs?
When selecting components for their applications, mechanical and electrical engineers, must understand some general guidelines for their PCB interconnect requirements. Below is a short list of nine of the most common and cost-effective pin retention designs and where they may be used. Press-Fit Barb — is specifically for non-plated through holes. This is the easiest and […]
