JEL SYSTEM CO,LTD Company Overview

The Gel Group supports users' businesses and contributes to people and society through two perspectives: "control" and "energy saving."

Gel System Co., Ltd. is engaged in the development of high-quality products at low cost. Focusing on our flagship product, the "Solid State Relay," we develop and manufacture control devices such as "Diode Modules" and "Thyristor Modules," and we are also committed to environmental products like "Electronic Breakers" and "Remote Monitoring Devices." Naka and Company, Inc. is a company that designs, manufactures, and sells crystal oscillators and crystal resonators. Through our unique frequency multiplication circuit technology and low harmonic removal technology, we provide high-frequency crystal oscillators that achieve stable oscillation and low phase noise without the need for precision processing of crystals (such as etching). Since July 2014, Naka and Company, Inc. has become a 100% subsidiary of Gel System Co., Ltd., joining the Gel Group. Naka and Company will continue to strive to be of service to everyone, and we ask for your continued support and cooperation.
