ABB 3HAC023621-004 Shrink Boot Adapter, Shell Size 16

Shrink Boot Adapter for ABB UTOW Shell-Size-16 Connectors

Specifications

Industrial Applications

• Strain relief and environmental sealing at the cable entry of UTOW shell-size-16 connectors in ABB robot cabling.
• Replacement of a cracked, hardened or damaged boot on UTOW shell-size-16 connector assemblies.
• Preventive maintenance where connector boots are inspected and renewed on a schedule in harsh (oily, dusty, washdown) environments.
• Used wherever ABB specifies a UTOW shell-size-16 connector boot (UTO16AD).

Design Purpose

A circular connector at a moving robot break point is only as reliable as its cable entry. Without strain relief, the cable flexes right at the connector backshell; without a sealed boot, coolant, oil and dust reach the contacts. ABB fits a defined shrink boot adapter (UTO16AD) on UTOW shell-size-16 connectors so the cable is supported and the entry is sealed against the environment.

Because the boot is defined by shell size and connector type, it is a fitment-specific accessory, not a universal boot. The correct article number is tied to the exact connector called out in the cabling / spare-parts documentation, so it must be matched by shell size and application rather than by appearance. This is a confirmed-fitment accessory, verified against the connector type designation, not a generic boot.

Common Failure Modes

• Boot cracking or hardening from heat, oil or ageing.
• Loss of seal allowing coolant, oil or dust into the connector.
• Strain-relief failure where the cable flexes at the backshell (boot not seated or wrong size).
• Mechanical damage from cable pull or routing against the manipulator structure.
• Wrong boot fitted (shell size / type mismatch) causing poor fit or no seal.
• Adhesive / heat-shrink failure from incorrect installation (too much or too little heat).
