It serves as a protective cover to shield the pins from dust, debris, and physical damage during handling, storage, or when the connector is unmated. The cap is a plastic plug with anti-static properties, making it suitable for environments where electrostatic discharge protection is a concern. This cap is a straightforward accessory — no contacts, no termination, no mating cycle count. Its job is to keep the male pins clean and undamaged until the connector is ready for service. The 37-position count matches standard high-density D-Sub layouts, so it fits the common shell size used for that pin count. The 1731120594 cap is made for male D-Sub connectors. It snaps over the pin side of the connector body, covering all 37 positions. It will not fit female D-Sub connectors — the shell profile and internal geometry are different. For a female D-Sub, you would need the corresponding female dust cap from the same FCT series. The plastic construction with anti-static properties means it won't generate a static charge that could damage sensitive electronics inside the connector. This is a practical detail for field service or bench work where you're handling boards or cables that feed into ESD-sensitive circuits.","metaTitle":"Molex 1731120594 Dust Cap, FCT D-Sub, 37-Position, Active","metaDescription":"Molex 1731120594 FCT dust cap for 37-position male D-Sub connectors.
