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 with a review of the three types of shielding, then considers how they are used in combinations […]
What are the six connector locking mechanisms?
Various locking mechanisms are found on connectors including bayonet, latch, lever, push-pull, screw, and snap-in. These represent the more common styles, not an exhaustive list. Locking connectors can support several functions like assisting coupling and uncoupling and improving the environmental ruggedness of the connection in addition to enhancing mechanical performance and preventing accidental uncoupling. This […]
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 is electric vehicle supply equipment (EVSE)?
EVSEs provide power to charge EV batteries at Level 1 and Level 2 voltage ratings. Electric vehicle (EV) owners rely on electric vehicle supply equipment (EVSE) to charge their batteries efficiently. Often referred to as charging stations or docks, EVSEs provide a reliable and safe connection between EVs, the electric grid, and other energy sources. […]
October 2023 Issue: Power & Energy Efficiency Handbook
Engineering a green mindset and sustainable future Growing up in the pre-2000s era with a power electronics engineer for a father, my family’s first introduction to power and energy efficiency efforts was primarily analog. The word “vampire” was associated with a TV show called Dark Shadows; it had nothing to do with standby power […]
How internal fiber-optic connector designs are advancing
Inside-the-box copper connector and cable IO-Link standards for data centers have been a significant focus of systems product development, particularly within consortia and industry standards groups. Some recent examples are internal 400G and 800G PECFF Top-of-Board, Ethernet, CXL, and the PCIe use of SFF TA 1002/1020 connectors. Other examples include twin-axial cables for memory, storage, […]
What plating options are available for high-power connectors?
Plating options are numerous and tend to fall into four categories: noble metals, passive metals, alloys, and dispersions. The first three categories are well established, while dispersions are just beginning to appear in response to the need for high-power connectivity in electric vehicle (EV) charging and similar applications. This FAQ starts with a brief review […]
Where are liquid-cooled industrial connectors used?
Liquid-cooled connectors are used in high-current, high-power industrial applications like electrochemical processes, welding, induction furnaces, electric arc furnaces, electrothermic processes, and electromagnets. This FAQ looks at various liquid-cooled cable and connector structures for carrying up to 60 kA. Two keys to optimizing the performance of liquid-cooled connectors and cables are minimizing the resistance in the […]
