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 […]
What are the benefits of screw machine interconnects?
As Principal Engineer for a large connector manufacturer, each day I am challenged by electrical engineers and mechanical engineers to help bridge their leading edge technology from one module to another. I remember years ago, when the pin grid array went obsolete to the emerging QFP quad-flat pack, people said that “screw machine was a […]
When should you use press-fit screw machine header pins?
Continuing the discussion on screw machine technology, here is a look at this technology, the advantages of using it and how to best utilize this technology in your engineering projects. Below is a list of the common styles of press-fit screw machine header pins: Press-fit barb has a fishhook shaped feature, typically featuring 15° angle. It runs […]
When should you use floating pin technology?
One of the biggest challenges facing assembly of SMT interconnects is maintaining lead coplanarity over a distance. The greater the distance, the more likely the PCB surface may display the effects of warp, twist, and thickness tolerances. If the device lead is seated too high above the solder paste, then this will be either a […]
