The Amphenol ICC DC37S064HTLF is a 37-position D-Sub receptacle with female sockets, part of the standard D-Subminiature family that has been a workhorse for serial and parallel data interfaces, instrumentation, and industrial control connections for decades. This is the receptacle (female) half — mates with the DC37P064HTLF male plug or any standard 37-pin D-Sub male connector with the same shell size 4 (DC, C) layout. The 37 circuits are arranged in two rows, giving you a dense but field-serviceable interconnect for signal-level wiring. Termination is via solder cup — each contact has a cup you solder a stripped wire into, making this a field-terminable connector for cable assemblies where you need to attach individual wires rather than crimp a terminal. A shielded shell with steel, tin-plated construction provides EMI/RFI containment for the signal bundle inside.
The 300 V rating gives adequate headroom for most signal and low-voltage control circuits inside an enclosure. The solder cup termination means you are hand-soldering each wire to the cup — no crimp tool, no die set. This is a field-repairable termination but slower to assemble than a crimp-and-poke contact. The unthreaded flange (housing/shell) means the connector uses jackscrews or slide locks for mating retention, not a threaded coupling nut. You will need the mating male connector with the corresponding hardware. Gold flash plating (a thin gold layer over nickel) provides enough corrosion protection for moderate mating cycle life in a controlled environment. For very high mating cycle counts or corrosive atmospheres, a heavier gold plating (15 µ" or 30 µ") would be specified — this flash grade is standard for general-purpose D-Sub use.
