Hirose right/left 90° black bend protection sleeve EFB-Elektronik 37549.1

The Hirose right/left 90° black bend protection sleeve by EFB-Elektronik (model 37549.1) is an accessory designed to provide mechanical strain relief for Hirose connectors where cables must exit at a 90° angle. Made for installations with limited space, the black sleeve reduces stress at the cable-to-connector junction and helps prevent deformation or breakage of conductor insulation and connector contacts. The sleeve is intended for use in network and electronic assemblies requiring a compact, angled cable routing solution.

Advantages

This bend protection sleeve offers a compact 90° routing option that minimizes bending stress and improves cable longevity without altering connector electrical performance. Its black finish provides a discrete appearance in professional installations and helps maintain consistent cable alignment. The sleeve is compatible with Hirose connector geometry and supports both right- and left-handed orientations to suit different cable exit requirements.

Suitable for

• Network patch panels and wall-mounted outlets with limited rear clearance
• Electronic devices and control units requiring angled cable exits
• Industrial and communication assemblies where strain relief is needed
• Applications that demand right- or left-oriented cable routing

Key specifications

• Orientation: 90° right and left options
• Color: black
• Function: mechanical bend protection and strain relief
• Compatibility: designed for Hirose connector form factors
• Typical use environment: network and electronic assemblies with space constraints

How to use

Slide the bend protection sleeve onto the cable prior to connector assembly, position it adjacent to the connector housing so the sleeve covers the cable-to-connector junction, and orient the sleeve for the desired right or left 90° exit. Ensure the sleeve is seated securely against the connector body to provide consistent strain relief. After installation, inspect that the cable bend radius meets the cable manufacturer's minimum bend specifications and that the sleeve does not interfere with mating or locking features of the connector.

Usage recommendations

For reliable performance, use the sleeve with compatible Hirose connectors and maintain manufacturer-recommended bend radii. Avoid excessive pulling force on the cable, and periodically check the sleeve and cable at the junction for wear or loosening in high-vibration or frequently flexed installations.
