## Long description

Hirose protective bend relief boot TM21 light gray for cable assemblies, model 37641.12 is an accessory designed to reinforce the strain relief zone of cable assemblies and connector exits. The boot slips over the cable jacket at the connector interface to reduce stress from repeated bending, abrasion and sharp routing angles, helping to maintain reliable electrical and data connections in network and electronic equipment installations.
Advantages
The Hirose TM21 bend relief boot provides a simple mechanical solution to reduce bending stress where cables exit connectors. Its light gray finish offers a neutral appearance for visible cable runs. By concentrating flex away from the connector termination, the boot can help prevent cable damage and intermittent faults while extending the service life of assemblies. The design is compatible with typical cable jackets and is intended for straightforward retrofit or factory installation.
Suitable for
Protecting connector exits in network equipment and electronic devices
Reinforcing cable jackets at tight routing points
Field installations and repairs where added strain relief is required
Environments with frequent cable movement or flexing
Key specifications
Colour: light gray
Form factor: protective bend relief boot for cable assemblies
Compatibility: intended for use with cable jackets at connector exits in network and electronic equipment
Primary function: reduce bending stress, abrasion and strain at the connector interface
How to use
Slide the Hirose TM21 bend relief boot over the cable jacket before terminating the connector or install it over an existing jacket if access permits. Position the narrow end toward the connector so the boot covers the transition between connector housing and cable jacket. Ensure the boot seats snugly against the connector body and cable jacket to provide continuous protection against bending and abrasion. No special tools are required for typical installations.
Usage recommendations
Use the Hirose TM21 boot where cables are subject to frequent movement, tight bends or exposure to abrasion. Verify that the boot’s internal diameter matches the cable jacket diameter for proper fit. For installations where environmental sealing or EMI shielding is required, combine the bend relief with appropriate grommets, overmolding or shielding solutions as needed.
