Sankosha Coaxial Surge Protectors
Sankosha's Coaxial Surge Protection Devices (SPD's) provide heavy duty protection from surges caused by lightning or other transients. Radio and wireless telephone communication equipment is particularly vulnerable because antennas are typically located in areas where the probability of exposure to lightning related surges is high. Damage caused by direct strikes to the antenna itself or induced surges through the grounding system is prevented when coaxial protectors are in place. These SPD's are well suited for Broadband, CATV, GPS and cellular applications. Gas Discharge Tube equipped coaxial surge protectors are ideal in high frequency transmission applications due to their low capacitance. When confronted by a fast rising transient voltage, the protector sparks over temporarily and diverts energy away from sensitive equipment. Damage to transceivers in remote locations is avoided. Coaxial SPD's are easily installed in series with the antenna line.

Sankosha U.S.A., Inc.
For over 75 years, Sankosha has developed and manufactured the Ceramic Gas Tube Surge Arrester (Gas Discharge Tube or GDT). Sankosha gas tube arresters protect personnel, equipment and circuitry from abnormally high voltages caused by lightning or electrical transients. Our surge protection devices have well defined surge-limiting characteristics enabling them to spark over (or breakdown) when the abnormal voltage on a line reaches a specific level. When sparkover occurs in the GDT, the surge is redirected to earth.
Sankosha’s gas tube arrestors are known for their quality. Throughout the world, products from our factories provide protection for equipment and personnel. Sankosha has been selling gas tube arresters in the U.S. since the seventies and Sankosha U.S.A., Inc., the company’s 100% owned subsidiary, was established in 1987 to better service the growing market in the Americas.
Different applications require different surge suppressors and Sankosha provides gas tubes to meet every need. Consumer electronics, modems, satellite, computer, CATV/Broadband, industrial, and telecom circuit protection are just a few areas that utilize our gas discharge tubes. Sankosha’s gas discharge tubes are extremely durable and provide the industry’s best impulse life specifications. They feature high surge ratings with very low capacitance and provide excellent response to fast rising transients.
Sankosha gas discharge tubes are available in axial leaded, radial leaded, surface mount, and special packages. High voltage gas tube models like the Y08SV-312B are designed for power supply applications where HiPot testing is required, and we also manufacture very small gas tube arrester models for surface mount applications where real estate is at a premium. Sankosha’s GDT’s come in both two and three electrode configurations. Discharge voltages from 75V to 6000V are available.
Sankosha’s RJ45 LAN SPD provide reliable surge protection of GigE (1000Base-T), 100Base-TX, 10Base-T and Power Over Ethernet (PoE) equipment. All four compact Local Area Network modules are equipped with RJ45 Connectors and can be used as stand alone surge protection devices. They are also designed with integrated clips for easy installation on a standard 35mm DIN rail.
In the 1970’s, Sankosha developed SAN-EARTH, the original conductive concrete groundbed. SAN-EARTH M5C is a fine powder used to build highly effective environmentally safe permanent grounding electrodes. SAN-EARTH M5C is manufactured in accordance with Sankosha’s ISO 9001 Quality Standards and conforms to IEC Standard 62561-7 which specifies the requirements and tests for earthing enhancing compounds producing low resistance of an earth termination system. Safe, economical and permanent, SAN-EARTH is the best grounding solution for both equipment performance and personnel safety.
