The Quiet Failure That Costs Thousands A procurement manager in Stuttgart once sent me a batch of unshielded RJ45 connectors for a new automotive assembly line. The installation looked clean. The cable tests passed. Three weeks later, the network began dropping packets every time the welding robots cycled. The root cause was not a bad … Read more

Detector Switch vs Micro Switch: What’s the Difference? When a product fails in the field, engineers often investigate firmware bugs, PCB defects, or component quality issues. Surprisingly, many failures originate from a much simpler source: selecting the wrong sensing switch. A common example occurs in consumer electronics and industrial equipment where designers use a micro … Read more

If you’re specifying a USB connector for a new product, you’ve probably run into three overlapping terms: USB-C, USB 3.0, and USB4. They sound like a version progression, but they actually answer three different questions — connector shape, data speed, and protocol capability. Choosing wrong can mean redesigning your PCB six months into production. This … Read more
