It provides a shielded enclosure with a 180° cable exit, accepting round cable. The backshell includes assembly hardware—a cable clamp and strain relief—plus 4-40 mating screws for secure attachment to the connector. The housing is black ABS plastic with nickel plating for EMI protection. ## Compatibility: Does It Fit a Standard DB25 Connector? This backshell is compatible with standard 25-position D-Sub connectors (shell size B). The 4-40 mating screws are included and align with the threaded inserts on the connector. ## Shielding and Cable Management The backshell is shielded, with nickel plating on the ABS housing to provide EMI/RFI protection for the cable assembly. The 180° cable exit routes the round cable straight out the back, and the integrated cable clamp and strain relief secure the cable and reduce mechanical stress on the solder joints. This is a two-piece design—the halves clamp around the cable and connector, then fasten with the included screws.","metaTitle":"Molex FKC 1727040120 Backshell, 25-Pos, Shielded, 180°","metaDescription":"Molex 1727040120 two-piece backshell for DB25 and HD44 connectors, shielded, 180° cable exit, includes 4-40 mating screws and strain relief.","metaKeywords":null},"attributes":{"series":"FKC, FCT 172704","packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["D-Sub & D-Shaped Connectors","D-Sub Backshells & Hoods"],"specifications":{"Mfr":"Molex","Color":"Black","Series":"FKC, FCT 172704","Package":"Bulk","Plating":"Nickel","Features":"Mating Screws 4-40","Hardware":"Assembly Hardware, Cable Clamp, Strain Relief","Material":"Acrylonitrile Butadiene Styrene (ABS)","Shielding":"Shielded","Cable Exit":"180°","Cable Type":"Round","Accessory Type":"Two Piece Backshell","Product Status":"Active","lifecycle_stage":"unknown","Primary Material":"Plastic","Base Product Number":"172704","Number of Positions":"25","Compatible D-Sub Size":"25pos and HD44pos","Compatible Shell Size":"B"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.6700","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$9.67000","currency":"USD"},{"qty":10,"price":"$8.40700","currency":"USD"},{"qty":100,"price":"$6.93600","currency":"USD"},{"qty":1000,"price":"$5.75896","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Does 1727040120 fit a standard DB25 connector?","answer":"Yes, it is compatible with 25-position D-Sub connectors (shell size B) and also fits HD44 connectors.
