The M85049/88S-15N is a straight banding-style cable backshell designed for circular electrical connectors. It is the AS85049 / GJB1784 standard part number, interchangeable with J1784/88S-15N, and is commonly used with GJB599 / D38999 Series III and Series IV connectors in shell size 15.
As an /88S-type accessory, the M85049/88S-15N provides self-locking coupling, EMI/RFI shield termination via banding, shrink-boot accommodation, and mechanical strain relief. The electroless nickel finish (N) supports corrosion resistance while maintaining electrical continuity for shielded harness assemblies.
- Conformant to national standard GJB1784 (equivalent to AS85049)
- Interchangeable with cross-reference part number J1784/88S-15N
- Straight banding backshell for EMI/RFI shield termination with AS85049/128 style bands
- Self-locking coupling (S) for improved vibration resistance during installation and service
- Shrink-boot accommodation for environmental sealing over the cable exit
- Electroless nickel plating finish denoted by the N suffix
- Shell size 15 for D38999 / GJB599 Series III and IV circular connector interfaces

| Requirement | Recommended Accessory |
|---|---|
| Straight banding / EMI shield termination | M85049/88 (this product family) - M85049/88S-15N |
| 45 degree banding backshell | M85049/89 series |
| 90 degree banding backshell | M85049/90 series |
| Cable clamp only, no EMI banding | M85049/38, M85049/49, or M85049/47 series by connector series and exit angle |
- Confirm shell size 15, self-locking style (S), finish (N), and cable-entry size before ordering.
- Use compatible banding tools and AS85049/128 style termination bands for shield termination.
- Install the shrink boot over the accessory barrel after band termination to improve environmental sealing.
- Verify connector series compatibility: /88S accessories are intended for Series III / IV interfaces, not Series I / II clamp styles.
- Where required by the harness drawing, add anti-loosening methods such as safety wire, thread-locking compound, or full heat-shrink over the accessory.
Choosing the M85049/88S-15N ensures form-fit-function compatibility with J1784/88S-15N supply chains while meeting GJB1784 / AS85049 requirements. The straight self-locking banding geometry supports EMI/RFI shield continuity, shrink-boot sealing, and reliable retention behind Series III / IV circular connectors in aerospace and industrial interconnect systems.
Order by the AS85049 designation M85049/88S-15N, or cross-reference as J1784/88S-15N, depending on your procurement standard. When requesting a quote, please confirm cable-entry size (02/03), mating connector part number, and required quantity.
