Electromechanical components are indispensable for a variety of applications in nearly all branches of industry. The sub-area of electrical engineering covers an enormous range of components, from relays and actuators to switches and connection systems to housing technology. At electronica 2022, leading companies from the industry will present the entire spectrum of electromechanics in Halls A2, B2 and B3. On November 16, 2022, the Electrical Connectors Forum will revolve around the Single Pair Ethernet (SPE).
Disrupted supply chains, scarce raw materials, high energy costs – this also affects the manufacturers of electromechanical components. On the other side the COVID-19 pandemic has increased the need for digital solutions in many areas of the business and the everyday. The manufacturing industry has long since been a part of this trend. So far, however, there has been no satisfactory solution for the field level, where thousands of sensors and actuators are currently connected via a complex and expensive Ethernet structure.
A change in technology is now on the horizon in the form of the Single Pair Ethernet (SPE). Switching from two- or four-pair cabling to one-pair cabling creates a consistent, Ethernet-based IP network infrastructure that saves space, weight and costs. SPE has already become indispensable in the automotive industry. Broadcom’s BroadR Reach enabled in-vehicle systems to simultaneously access information over single-twisted pair cables for the first time. Combined with the switch technology according to IEEE 802.3, it is possible to transmit up to 100 Mbit/s. In addition to the reduction of material, installation space and costs, as well as consistent real-time communication, SPE also opens the door to factory, process and building automation. Experts describe it as a key technology for the IIoT.
According to a recent study by The Insight Partners, the global SPE market will grow from $1.90 billion to $3.60 billion by 2028 at a CAGR of 9.6 percent. A broad SPE portfolio already exists. Companies such as Amphenol, Harting, Phoenix Contact, Telegärtner and Würth Elektronik will be presenting related products at electronica. And there will be expert knowledge on the Single Pair Ethernet on November 16, 2022 at the Electrical Connectors Forum in Hall B3 from 10:00 a.m. to 1:00 p.m.
The situation is almost the opposite with electromechanical relays (EMR). They continue to resist solid state relays (SSR) with characteristics such as low power consumption, low cost, long life and easy maintenance. For example, electromechanical circuit board relays are still used in almost all building automation systems. However, building technology is not the only source of growth. Automation, the use and generation of alternative energies, and changing mobility are also continuing to help the market for electromechanical relays to generate good sales. Analysts at Infogence Global Research see the global electromechanical relay market growing from $5.94 billion this year to $7.25 billion by 2027, at a CAGR of 4.07 percent. Manufacturers such as Omron, Panasonic, Phoenix Contact and Weidmüller are showing electromechanical relays at the trade fair that cover an enormous number of applications – ranging from controllers, sensors and actuators to light control devices, motors and timers to access controls.
Electromechanical input systems such as switches, buttons and keyboards are not going out of fashion either. Manufacturers experienced lower demand from the electronics and automotive industries due to the pandemic. However, this was partly offset by the healthcare sector, as, against the background of the pandemic, governments invested heavily in struggling healthcare systems. In addition, operating elements for hygienic applications generated additional sales. According to Global Market Insights, the market surpassed the 13 billion mark in sales in 2021 and will grow at a CAGR of around 6 percent until 2030. The analysts see excellent market opportunities through the introduction of industrial automation technologies such as IIoT, AI and robotics. In addition, electromechanical switches in modern vehicle cabins are increasingly optimizing comfort, safety and access to a wide range of functionalities. At electronica, companies such as Bopla, C&K Components, Georg Schlegel, Kundisch, Panasonic, Rafi and Schurter will present the entire range of electromechanical control elements.
