HARTING T1 Single-Pair Ethernet (SPE) Connector

Harting’s single-pair ethernet (SPE) connector provides Ethernet access for every device on a network. The connector complies with all relevant standards and also harmonizes with the SPE cable standards.

The T1 industrial® connectivity solution was designed to be the standard interface for industrial Single Pair Ethernet applications and can accomplish communication across the common industrial Ethernet protocols (Ethernet/IP, Profinet, EtherCAT and more). The Harting SPE connector ranges from IP20 to IP67and currently, there are metric variants (M8 and M12) with further variants on the product roadmap. To fit all applications and truly be the standard for industrial applications, the connector’s mating interface was designed to be the same and interoperable across all IP-ratings.

T1 Connector Mating Interface

The shield plates are manufactured out of stainless steel, and Harting implemented a robust core and a reliable cable gland provide enough stability to widthstand all applications across various IP-ratings.

The Standard Mating Face

For the past few decades, many variants of industrial Ethernet have been designed in reaction to the needs of the market. Some conditions call for enclosures with quick-release locks or screw terminals with metric/inch dimensions. Depending on the field of application, IP-ratings could be IP20 or IP67.

Instead of being reactionary with Single Pair Ethernet, HARTING took a proactive approach to designing one industrial connectivity solution that would fit all application needs.

In order to be able to use these proven sizes and dimensions further, the T1 Industrial® interface has been developed using a container principle. The T1 connector interface fits into well-known M8 and M12 circular housings, or other housings and can thus adopt the protective properties of this proven standard. At the same time, an IP20 T1 Industrial® can be plugged into an open IP 65/67 interface for service purposes, making it easy to maintain.

A Strong Ethernet Connection

For the moment when the plastic clip of the LAN connector has broken off, such moments of material weakness have no place in industrial applications. For this reason, the Harting T1 connector interface is equipped with a robust metal lock made of stainless steel for a strong connection even under harsh conditions.

Harting T1 Industrial Connector: Miniature Design, Robust Placement

This Harting SPE is not only a gamechanger for the interface and cabling, it also saves a lot of space. Miniaturization is a major point in design criteria for next generation products, and the market is taking shock and vibration testing much more seriously as on-machine application becomes more popular. For these reasons, component mounting and stability must not be neglected. The T1 Industrial® PCB mounted socket has four robust THR shield contacts, which are reliably soldered into the PCB and provide the best stability. The contacts are also designed as pin-in-hole variants. Should the socket have to absorb unexpected high forces, they cannot simply detach from the surface.

Shielding and Protection for Ethernet Connectors

In order to meet the high frequency requirements of SPE, SPE infrastructure must be particularly well shielded. The standard interface now developed for industry has therefore been fundamentally designed to meet these requirements. A completely symmetrical mating face in connection with a horizontal device socket ensures consistent and reliable running times in both copper wires in order to avoid signal overlapping. A complete 360° closed stainless steel jacket, which encloses the entire connector, ensures excellent electromagnetic compatibility (EMC) and protects what is important: the data of your production.
