It provides 360° shielding for the cable-to-connector transition, with a zinc die-cast body and nickel plating that gives a consistent ground path and corrosion resistance. ## What's in the Box — Hardware Included This backshell ships with the assembly hardware, cable clamp, and strain relief already included — no separate hardware order needed to complete the cable assembly. The 4-40 mating screws are the standard thread for DB25 backshells, securing the two halves together and to the D-sub connector. The cable clamp grips round cable jackets evenly, and the two-piece design means you can terminate the D-sub connector first, then assemble the backshell over the wiring — a field-serviceable approach that saves a trip back to the bench.","metaTitle":"Molex FMK 1727040100 Backshell, 25 Pos, 180°, Shielded","metaDescription":"Molex 1727040100 FMK series two-piece metal backshell for DB25 D-sub.","metaKeywords":null},"attributes":{"series":"FMK, 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":"Silver","Series":"FMK, FCT 172704","Package":"Bulk","Plating":"Nickel","Features":"Mating Screws 4-40","Hardware":"Assembly Hardware, Cable Clamp, Strain Relief","Material":"Zinc Die Cast","Shielding":"Shielded","Cable Exit":"180°","Cable Type":"Round","Accessory Type":"Two Piece Backshell","Product Status":"Active","lifecycle_stage":"unknown","Primary Material":"Metal","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":"$11.2600","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$11.26000","currency":"USD"},{"qty":10,"price":"$9.79400","currency":"USD"},{"qty":100,"price":"$8.08000","currency":"USD"},{"qty":1000,"price":"$6.70887","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/43ba034aff072f5b8d6b1b788d5aee67.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does 1727040100 include mounting hardware?","answer":"Yes, the 1727040100 ships with assembly hardware, a cable clamp, and strain relief, plus 4-40 mating screws.
