PMTJ Series Data Line Surge Protection

Ideal for RJ11- and RJ45-Style Twisted Pair Interfaces

The PMTJ Series of surge protectors for RJ45 and RJ11 connectors will ensure the reliable operations of devices in a wide variety of environments. We offer protection for LAN interface technologies such as Ethernet,10/100Base-T, CAT5, CAT5e, CAT6, and Power over Ethernet. For WAN and Telco applications, we offer protection for ISDN, T-1, E-1, DDS, analog dial-ups, and more. Additionally, our Custom Products Division provides a solution for almost any application that sends data, voice or video over copper interconnects.

PMTJs Offer:

State-of-the-art, avalanche diode and thyristor technology.
Compact, in-line installation.
High-speed, high-energy handling capability.
Low shunt capacitance to reduce signal loss.

You Receive:

Affordable, superior, equipment protection.
Improved reliability and maximized system up-time.
Protection at the interface card.
Adaptability to most industry applications.

The PMTJ Series devices guard sensitive data networks against lightning induced surges, ac power interference, electrostatic discharge, and ground loop energies. Typical applications include: NICs, switches, hubs, repeaters, bridges, routers, point-of-sale terminals, modems, fax machines, telephones and most other types of communications equipment utilizing RJ45 or RJ11 modular telephone jacks.

High-speed avalanche diode technology is used in conjunction with low capacitance circuitry, enabling the protectors to function at a much greater bandwidth without causing signal degradation.

Standard units are available with up to 8 wires protected on the RJ45 devices, and up to 6 wires protected on the RJ11 device. All this, in combination with their small size, makes the PMTJ exceedingly versatile.

Installation

To install, insert the protector in series between the incoming communication line and the I/O port of the equipment to be protected. The protector ground wire must be connected to the metal chassis of the equipment being protected. Units should be installed at both ends of the data cable for the most effective protection.
