What it is and where it fits
The Molex 936010297 is the 24-circuit female insert in the GWconnect S-E modular industrial connector series — Size 24B refers to the standard DIN rectangular housing envelope that defines the board footprint and compatible hoods. It carries 24 signal or power circuits plus a dedicated protective earth (PE) contact, terminated via screw clamps into copper alloy contacts finished in silver over the full mating surface. The polycarbonate housing meets UL94 V-0 flame retardancy, which governs placement near live bus bars or in confined enclosures.
What the ratings mean for selection
16 A per contact at 500V defines this as a power-range insert in the S-E series — it sits above signal-duty members and handles branch power distribution in control cabinets and motor drives. Silver plating on the contacts gives better conductivity retention under repeated thermal cycling than tin, and the full-surface silver finish means both the mating interface and the wire termination zone benefit from the same oxidation resistance. Screw termination accepts a range of wire gauges into the copper alloy barrel without requiring a crimp tool — the limiting factor on wire size is the barrel geometry, not the contact rating. The -40°C to 125°C operating window covers freezer environments and machine-tool bay conditions; the upper limit is set by the polycarbonate housing material rather than the contact system, so de-rate current if the insert runs near the ceiling in a sealed hood. The UL94 V-0 listing is the compliance flag for confined-panel use — a V-2 rated insert cannot go in the same enclosure location without a supplemental fire barrier.
