(5) Mating and Accessories

The 2-6447232-3 header mates with corresponding SUPERSEAL 1.0mm series receptacle connectors (not specified in provided material). Compatible receptacle contacts for wire termination include part numbers 3-1447221-3, 3-1447221-4, 2461132-1, 2461132-2, 1-2461132-1, and 1-2461132-2 with gold, silver, or tin plating as indicated.

(6) Conclusion

The 2-6447232-3 is a 34-position, 4-row, vertical, sealed wire-to-board header for signal applications. It features a 3 mm pitch, gold-plated pins (1 mm diameter), and a 3 A current rating per contact. The connector is rated for 250 V (AC/DC) and operates from -40°C to +125°C, with IPX7 sealing. It meets RoHS, ELV, and REACH compliance (SVHC-free) but is not low halogen. Termination is through-hole soldering to PCB, and packaging is in tubes of 14 pieces. When mated with appropriate SUPERSEAL 1.0mm receptacle connectors and using the recommended crimping specifications (wire sizes 0.5 mm² to 1.25 mm², crimp height/width limits, tensile strength minima), the system provides reliable signal transmission in harsh environments.
