What are the performance requirements for multidrop SPE connectivity?
Specifications are provided for the insertion loss, return loss, and mode conversion loss in the link and mixing segments of a Single-Pair Ethernet (SPE) network. Connector specifications are also provided for coupling attenuation, impedance, return loss, and dielectric strength. This article begins by briefly examining where multidrop fits in the range of Ethernet connectivity options. […]
What are ZIF and LIF connectors and where are they used?
How low contact resistance is achieved can be a key differentiator between zero insertion force (ZIF) and low insertion force (LIF) connectors. Many LIF connectors have a low contact resistance of about 30 mΩ when mated without needing a locking mechanism. ZIF connectors generally require a locking mechanism to achieve low contact resistance and a […]
What are the four MICE elements and three performance levels for connectors?
IEC 11801-3:2017 provides guidance for designing physical infrastructure to support network communications in a manufacturing environment. That guidance is in the form of four MICE elements and three performance levels. The four elements of the MICE acronym include Mechanical, Ingress, Chemical/climatic, and Electromagnetic compatibility. The MICE standards define three performance levels and apply to cabling […]
How do the three types of shielded cables work?
The three basic types of shielding for electromagnetic interference (EMI) in cables include strands of braided copper and similar metals, spiral shields, and foil or tape shields. They can be used separately or in combination. This FAQ begins by reviewing the three types of shielding and then considers how they are used in combinations for […]
What are the five connector contact termination styles used for?
The five basic connector contact termination styles include solder, press-fit, clamp, crimp, and insulation displacement (IDC). In some cases, there are variations. This FAQ focuses on the termination of electrical signals, not fiber optic termination styles. Selecting the best termination style is important since the terminations provide stable electrical and mechanical connections and need to […]
Design World presents the 2023 LEAP Awards Winners: Connectivity
Now in its sixth year, Design World’s LEAP Awards continue to showcase the best engineering innovations across several design categories. It’s a large undertaking that wouldn’t be possible without the commitment and support of the engineering community. Each year, the editorial team assembles OEM design engineers and academics to create an independent judging panel. Below […]
What’s a heavy-duty industrial connector?
A heavy-duty industrial connector (HDC) is a rectangular connector that can handle power, data, and signal pins in a single housing and operate in harsh environments. While there are also standardized circular industrial connectors, they are not classified as HDCs. HDCs are found in robotics, automation, machine control, power conversion, and motion control applications. This […]
USB Type C-standardization – what you need to know
In a world where technological advancements seem to occur at the speed of light, it’s imperative to stay informed and prepared for the next wave of innovation. The digital landscape is evolving, and at the forefront of this transformation is the imminent standardization of USB Type C in the European Union. This unassuming yet powerful […]
What are the key tests for HVAC/harsh environment connectors?
Connectors are complex assemblies whose performance is based on interactions of electrical, mechanical, environmental, and materials factors. Extensive testing is required to ensure proper performance, and numerous industry standards have been developed for that purpose. This article reviews 13 tests across three key performance indicators for connectors, including electrical, mechanical, and environmental considerations for connectors […]
