Thermoshrinkable Enclosure Jakmet OTU-L 40 x 60 MK - model 1610321

Thermoshrinkable enclosure Jakmet OTU-L 40 x 60 MK (model 1610321) is a heat-shrink protective housing designed for electrical and electronic assemblies. The enclosure provides insulation and environmental protection by shrinking to form a tight seal around components after application of heat. The 40 x 60 size format suits compact modules and small connector blocks where a durable, conformal covering is required during installation and maintenance.

Advantages

The Jakmet OTU-L thermoshrinkable enclosure offers reliable sealing against dust and moisture when correctly applied, creating an insulating barrier that reduces the risk of short circuits and corrosion. Its heat-shrinkable material conforms to irregular shapes and provides mechanical protection for solder joints and connectors. The product is compact and lightweight, allowing use in constrained spaces without adding significant bulk.

Suitable for

• Protecting small PCB assemblies and connector joints
• Insulating wiring splices and terminal blocks in control panels
• Sealing sensor modules and compact electronic modules
• Applications where a low-profile protective cover is needed

When it may not be suitable

This thermoshrinkable enclosure is intended for compact components and may not be appropriate for larger assemblies or enclosures that require significant internal space. It requires a heat source for installation; therefore it is unsuitable where heat application is impossible or would damage nearby components. It does not replace rigid housings where mechanical impact resistance or long-term structural support is required.

Key specifications

• Type: Heat-shrinkable protective enclosure
• Material: Thermoshrink polymer (heat-activated shrink material)
• Nominal size: 40 x 60 (width x length in mm)
• Primary function: Insulation, sealing and mechanical protection for small assemblies
• Installation method: Heat-shrink application requiring controlled heating

How to use

Position the enclosure over the components to be protected, ensuring complete coverage of solder joints, connectors or wire splices. Apply heat evenly using an appropriate heat gun or controlled heating tool until the material shrinks and forms a tight, conformal fit around the parts. Allow the assembly to cool so the material sets and the seal stabilizes. Verify that the enclosure does not interfere with connectors or mounting points before finalizing the installation.

What to consider before purchase

• Confirm the internal dimensions required to fully cover the target components (40 x 60 mm nominal size).
• Ensure availability of a suitable heat source and that nearby components tolerate heat during application.
• Assess whether a heat-shrink enclosure provides sufficient mechanical protection for the intended environment.
• Verify material compatibility with the chemicals or temperatures expected in the application area.

Usage recommendations

For consistent results, use a regulated heat gun and apply heat in sweeping motions to avoid local overheating. Pre-test on a spare assembly when possible to determine the correct distance and temperature for the specific installation scenario. Inspect the cooled assembly for uniform shrinkage and proper sealing before deployment.
