Wieland Electric Introduces Pluggable Printed Circuit Board Terminals

The newly designed PCB headers from Wieland Electric offer a particularly high contact density inside a compact housing. The two-tier and three-tier headers are available in 2 to 16 pole designs per tier, in straight or angled versions, with or without latching flanges for mating connectors. The three-tier version, wiecon 8513 SDGN, is a true market innovation, featuring a maximum of 48 poles for the connection of 1.5 mm² wires. The two-tier terminal blocks, wiecon 8513 SEGN, provide up to 32 poles. The wiecon 8513 BS mating plug connectors are equipped with push-in technology for quick wiring without tools.

“Miniaturization of electronic modules means PC boards are growing smaller and the number of contact points per surface is continuously growing,” said Mark Matheny, president of Wieland Electric. “Given the limited size and electrical installation conditions of PCB terminals, the new Wieland high density electrical connectors offer a robust and highly desirable connection density to the circuit board.”

The PCB headers are highly temperature resistant and meet EN 61760-1 standards. They are ideally suited for the lead-free THR (through hole reflow) soldering process used in surface mount technology. Due to their highly accurate spacing, the headers can be fitted automatically, even when both sides of the PC board are used. The PPA (polyphthalamide) material with which they are made shows a high tracking resistance, with a comparative tracking index (CTI) value over 600. The angled PCB headers are ideal for contacting control devices or controllers in automation technology, and feature corresponding cut-outs at the front panel.
