[Information] Basic Knowledge of Connectors Release Announcement

Why does it get hot? An introduction to the mechanism of heat generation when electricity flows and the temperature of connectors.

This document explains connectors and heat generation. It covers the mechanism of heat generation when electricity flows, as well as the temperature of connectors and their rated current. We hope that people with detailed knowledge, as well as those who are not usually involved with connectors, can enjoy learning about them. 【Contents (excerpt)】 ■1. The mechanism of heat generation when electricity flows 　・Column 1: Heating of electric heaters and air conditioners 　・Column 2: Superconductivity ■2. Temperature of connectors (heat generation and dissipation) ■3. Rated current *For more details, please refer to the PDF document or feel free to contact us.

How does electricity transmit? Introducing the mechanism and variations of ODU connectors.

Isn't it true that there isn't a day when we don't touch connectors such as plugs, USBs, LANs, and smartphone charging cables? A connector is a device used to transmit electricity, but how does electricity actually flow? In this document, I would like to briefly explain that mechanism. 【Contents (excerpt)】 ■1. The mechanism of electricity transmission through connectors ■2. Things that hinder the flow of electricity 　(a) Irregularities on the surface of metals 　(b) Insulating coatings on metal surfaces ■3. Defeating the hindrances 　(a) What can be done to eliminate irregularities on the metal surface? 　(b) What can be done about the insulating coating on the metal surface? *For more details, please refer to the PDF document or feel free to contact us.

Contec Co., Ltd. has started selling the "SH-9210TSN," an industrial managed switching hub that has obtained CC-Link IE TSN recommended network wiring component certification Class B. It features dual power supply redundancy, a DC power input, eight gigabit ports, and two SFP slots. The SH-9210TSN complies with IEEE 802.3ab (1000BASE-T), IEEE 802.3u (100BASE-TX), and IEEE 802.3 (10BASE-T) standards, and is designed for use in environments where quiet operation and long lifespan are required due to its fanless design. Additionally, it achieves an operating temperature range of -10 to 65°C thanks to its excellent heat dissipation metal casing. It can be installed on a 35mm DIN rail or mounted on walls using various mounting brackets. In addition to a wide-range DC power input (12-48VDC), it supports input from two power supply lines and includes various managed functions for network management, control, and reliability enhancement.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
