From March 14 to 18, 2023, IFPE Las Vegas, one of the most respected trade shows for fluid power, power transmission and motion control, took place. Thomas was also represented at the show with innovative solutions. In their luggage: products that promise maximum efficiency and precision in the off-highway segment. And plenty of ideas on how to realize future trends such as steer-by-wire. Highlights included the Integrated Pilot Head (IPH), the digital electrohydraulic actuator (EHA) and the Compact Pilot Actuator (CPA).

From March 14 to 18, 2023, IFPE Las Vegas, one of the most respected trade shows for fluid power, power transmission and motion control, took place. Thomas was also represented at the show with innovative solutions. In their luggage: products that promise maximum efficiency and precision in the off-highway segment. And plenty of ideas on how to realize future trends such as steer-by-wire. Highlights included the Integrated Pilot Head (IPH), the digital electrohydraulic actuator (EHA) and the Compact Pilot Actuator (CPA).
CAN-controlled with integrated intelligence: the EHA and EMA
Thomas has developed its Electro Hydraulic Actuator (EHA) and Electro Mechanic Actuator (EMA) for construction machinery, cranes, and steering applications with particularly high system safety requirements. What makes both of them unique is that they are “connected.” Specifically, they are CAN-controlled units for hydraulic directional control valves that boast short response times, a high degree of precision, and consistent motion control. They can be actuated via SAE J1939, CANopen, or a proprietary bus, and the characteristic and flow linearization curves can both be configured. What is more, the EHA and EMA come with integrated intelligence that is connected to the higher-level system and supplies it with data for control and optimization. This means that the system always knows whether the sensors integrated in the EHA and EMA are working correctly. Thus both units improve the efficiency and reliability of the hydraulic systems and deliver greater benefits for the customer. The EMA is ideal for applications that call for maximum system stability and motion dynamics because it is actuated mechanically. Meanwhile, the EHA is tailor-made for applications that place particularly high demands on safety, as it comes equipped with corresponding safety features in accordance with DIN EN ISO 13849.
Focusing on the future
The technologies used inside the EHA and EMA also offer another key benefit for manufacturers, namely that they are based on the Thomas Electronic Standard (TES) – a modular system with standardized interfaces. The TES was developed based on Thomas’s “Sense. Think. Act.” strategy and enables products to be developed safely, cost-effectively, more flexibly, and, most importantly, much faster.

We used IFPE Las Vegas to exchange ideas with the numerous visitors to our booth about our solutions for electrification, digitization and automation in the off-highway world. Thomas also deals with topics such as steer-by-wire, control valves for hydrogen applications or integrated valve solutions for thermal management in battery-powered vehicles. We are already thinking about tomorrow’s technologies today and are taking away many ideas and impressions from the trade show.
Valve concepts re-envisioned: the IPH and CPA
With its Integrated Pilot Head (IPH) and Compact Pilot Actuator (CPA), Thomas is once again demonstrating how the company likes to think outside the box. Both represent completely innovative, cost-efficient valve concepts.The IPH, for instance, is a proportional pressure-reducing valve that is the only one of its kind on the market and that is ideally suited to compact construction machinery. Because all its hydraulic functions are contained within the solenoid, it does not need a valve sleeve on top. This makes it compact and space-saving while maintaining a flow rate of 2,5 l/min. What is more, the IPH also makes installation easier, because the connection interface does not require any time-consuming drilling. And, last but not least, an integrated filter element protects the hydraulic connections and prevents system contamination.
Compact valve concept: Integrated Pilot Head (IPH)
As its name suggests, the Compact Pilot Actuator (CPA) also features impressively small dimensions. The concept has already made a splash once, specifically at its world premiere at bauma in 2022. This is hardly surprising, as the CPA is the only proportional control valve for the off-highway sector to be a mere 26 mm wide. This means it has the potential to become a game-changer for manufacturers of small construction machinery, as main control valves for mini excavators and similar systems can be made smaller than ever before. And because only one screw instead of two now needs to be tightened during assembly, the CPA also speeds up production. These and other product highlights will be available to view at Thomas’s trade show booth. Thomas is the perfect development partner and system supplier for innovative and customized electronic actuator solutions for fluid and mechatronic applications based on efficient standards.
