Overview
The Sumitomo Electric Lightwave JR-7S Thermal Jacket Remover is a professional-grade, battery-powered tool engineered for the precise removal of fiber coatings. Designed for both field splicing and production environments, it provides a consistent, clean strip for single fibers, supporting coating thicknesses of 250μm to 900μm in a single pass.
Constructed with a rugged metal lid for durability, the JR-7S features a dual-action mechanism that significantly reduces the manual force required for stripping. This ergonomic design helps minimize technician fatigue during repetitive tasks. The device is built to withstand demanding field conditions, featuring IPX2 water protection and shock resistance.
Operating flexibility is achieved through four adjustable temperature settings ranging from approximately 80°C to 140°C. The unit includes a power-saving mode, capable of delivering up to 600 removal cycles on a single charge of its 7.4V 1620mAh battery, ensuring extended operation for busy work days.

Frequently Asked Questions
What is the primary benefit of a thermal jacket remover?
Thermal jacket removers use heat to soften fiber coatings, which allows them to be removed cleanly without applying significant mechanical force that could nick or weaken the glass fiber.
Does this unit work for ribbon fiber?
No, the JR-7S is specifically designed for stripping single fibers.
How many temperature settings are available?
The device features four adjustable temperature settings ranging from 80°C to 140°C.
Is the battery included?
Yes, the unit comes with a 7.4V 1620mAh rechargeable battery.
Can I use this tool in the rain?
The device is IPX2 rated, which provides protection against dripping water, but it should not be submerged or exposed to heavy rain.
