Technology Notes
Short technical notes on connected systems, embedded intelligence and export-ready electronics.
01Choosing the Shell Size and Contact Count for a Push-Pull Connector
A four-step selection path from circuit requirements to cable cross-section, contact layout and shell size.
02Preventing Mismating on Push-Pull Connectors: Keying Options Explained
Positioning-pin angles, half-moon keying and stepped insulators — how each TRCONN series stops a wrong-line connection.
03Solder-Wire, Straight-Pin PCB or Elbow-Pin: Choosing Push-Pull Connector Terminations
Three termination layouts share the same shells — how to pick the one that matches your harness shop or your board.
04IP Ratings on Circular Connectors: What IP50, IP67 and IP68 Actually Guarantee
The two digits, what each level covers, and the mated-pair condition that every waterproof rating depends on.
05How to Read a Push-Pull Connector Part Code
Shell type, size, contacts, keying and accessories are all encoded in one string — here is how to decode it and order the exact connector you need.
06TRCONN B Series Push-Pull Connectors: 2–32 Contacts Across Six Shell Sizes
What the B Series covers — shell sizes, materials, electrical data and the plug and socket family — in one reference.
07How Push-Pull Self-Locking Connectors Work
The three-stage mechanics behind push-to-lock, pull-to-release circular connectors, and why they suit high-density panels.
