24 Circuits on a 0.100" Grid — Board-to-Board Routing
The 66527-012LF: The right-angle through-hole orientation routes the mated pair parallel to the PCB, which keeps the z-height low in an enclosure where the board stack is tight. Rated at 1250V, this receptacle handles industrial and telecom power distribution — not just low-voltage signal. The operating range from -65°C to 125°C means it lives through thermal cycling in automotive engine compartments or outdoor telecom cabinets without the housing cracking or the contacts losing retention.
This is a female socket receptacle — it mates with a 0.100" pitch dual-row pin header (male). For vibration-prone environments, a header with a locking ramp or a secondary retention feature is worth considering. The tin-plated solder tails (100 µinch) wet well with lead-free solder profiles.
