FCT from Molex D-Sub Connector Female 5 Way Straight Screw Mount 20A Die Cast Zinc FMK3G-5W5SA-5938 / 1731140090

The FCT from Molex FMK3G-5W5SA-5938 / 1731140090 is a heavy-duty 5-way straight D-sub connector, designed specifically for demanding industrial and automation applications that require high-current capacity and robust performance. As a female connector with a screw mount configuration, it is intended to ensure reliable, secure connections even in harsh environments where mechanical vibration, temperature extremes, or electrical interference might otherwise compromise system integrity.

Constructed with a die-cast zinc housing, this connector offers enhanced mechanical strength and protection against electromagnetic interference, making it a preferred choice for high-reliability systems. The copper alloy contacts are plated with gold over nickel, providing excellent conductivity and corrosion resistance. This structure supports a maximum current rating of 20A per contact, which is considerably higher than standard D-sub connectors, allowing for both signal and power transmission in a single connector footprint with a mixed 5W5 layout.

The FMK3G-5W5SA-5938 / 1731140090 model operates within an extended temperature range from -55°C to +210°C, making it suitable for installations where elevated or fluctuating temperatures are common. Its screw locking mechanism and included hardware facilitate stable panel or bulkhead mounting, preventing accidental disconnection in critical electrical and electronic assemblies.

With a voltage rating of up to 1000 V AC, this D-sub connector ensures safe operation in varied industrial contexts, protecting sensitive equipment and personnel. It is especially well-suited for cable connections in automation systems, electrical control panels, and environments exposed to mechanical or electrical stresses.

Applications for this FCT from Molex D-sub connector are extensive, encompassing automation equipment, factory control systems, industrial instrumentation, telecommunication infrastructure, and complex machinery that demand both power and data interfaces in a compact connector.

With UL recognition and compliance to global application standards, this connector helps engineers and integrators meet system design and regulatory requirements effectively, supporting reliable operations in manufacturing, telecommunication, and electrical control sectors.
