The Hirose HMUB-SH-1(40) is a sleeve holder accessory in the HMU series, designed specifically for use with HMUB connectors. It serves as a protective sleeve that fits over the connector body, providing strain relief and cable management in harness assemblies.
The sleeve holder mates with the full range of HMUB connectors — it is not a connector itself but a cable-side accessory that slides over the connector backshell. The UL94 V-0 rating tells the compliance engineer this part is accepted in equipment requiring flame-retardant plastics. For the harness builder, the -25°C to 70°C window means the sleeve stays flexible enough for assembly in cold environments without cracking.
