Wieland Electric's wiecon 8513 range of PCB headers is designed to offer a particularly high contact density within a compact housing. As PC boards decrease in size and the number of contact points per surface continues to grow, the limited size and electrical installation conditions of PCB terminals reduces the contacting options. In response to market demands, Wieland has engineered the new 8513 headers and plugs to allow users to connect wires with cross sections of up to 1.5mm2.
These new two- and three-tier PCB headers are available with 2–16 poles per tier, in straight or angled versions, with or without locking flanges for mating connectors. The three-tier option, wiecon 8513 SDGN, has a maximum of 48 poles for the connection of 1.5mm2 wires, while the wiecon two-tier 8513 SEGN provides up to 32 poles. The wiecon 8513 BS mating plug connectors are equipped with push-in technology for fast wiring with no need for tools.
Wieland's wiecon PCB headers are temperature-resistant and suitable for the lead-free THR (through-hole reflow) soldering process used in SMT processes. Due to their highly accurate spacing, the headers can be fitted automatically, even when both sides of the PC board are utilised. Another benefit is the PPA (polyphthalamide) material that provides high tracking resistance, with a CTI value of over 600. The angled PCB headers are designed for connecting field devices or controllers in automation technology.
