Heilind Expands High-Power Lineup with Innovative Molex SideWize Connectors

WILMINGTON, Mass. – January 19, 2026 – Heilind Electronics, a leading global distributor of electronic components, has announced a significant expansion of its high-power interconnect portfolio with the addition of the Molex SideWize High-Voltage Connector family. The move positions Heilind to better serve engineers grappling with the intensifying demands for power density, operational safety, and spatial efficiency in next-generation electrical systems.

As industries from automotive to data infrastructure push the boundaries of performance, the components holding these systems together are under immense pressure to evolve. The SideWize connectors represent a direct response to this trend, offering a sophisticated solution for high-voltage, high-current power distribution in applications where every millimeter counts.

A Technical Leap in Compact Power Design

The Molex SideWize series distinguishes itself with a unique right-angle architecture, a critical feature for designers working within highly constrained environments. Traditional straight connectors often force engineers to accommodate wide cable bend radii, consuming valuable space and placing mechanical stress on connection points. SideWize’s design eliminates this challenge, allowing for cleaner, more direct cable routing right at the panel interface. This is further enhanced by a 360° cable assembly rotation capability, which grants installers unprecedented flexibility in cable management and dressing after the connector is mated.

Beyond its space-saving geometry, the SideWize family delivers formidable power handling. With ratings up to 80.0A and 1,500V per UL 4128, these connectors are built to support the industry's trajectory toward higher wattage systems without the corresponding increase in heat or installation complexity. This capability makes them a robust alternative to traditional compression lugs, which often require more time-consuming and specialized installation procedures.

Safety, a paramount concern in high-voltage applications, is woven into the core of the SideWize design. The connectors feature a touch-proof, finger-safe construction to protect technicians and operators from electric shock. Adherence to low-halogen material standards ensures global compliance and environmental safety. To prevent connection errors during assembly—a common source of system failure—the connectors incorporate color-coding and unique footprints for different configurations. A positive-locking latch provides tactile and audible confirmation of a secure mate, preventing accidental disconnection due to vibration or handling. At the chassis interface, IP67-rated sealed bulkheads provide robust protection against dust and moisture ingress, ensuring reliability in demanding industrial settings.

Meeting Surging Demand in High-Growth Markets

The introduction of SideWize connectors through Heilind’s extensive distribution network is timed to meet explosive growth in several key technology sectors. The market for high-voltage and high-current connectors is expanding rapidly, with some market analyses projecting a Compound Annual Growth Rate (CAGR) of over 7.5% to reach a market value exceeding $7 billion by 2034. This growth is fueled by global megatrends in electrification and digitalization.

In the electric vehicle (EV) sector, where the market is expected to grow at a CAGR of over 20% in the next decade, SideWize connectors address the critical need for compact, reliable power distribution within battery packs and charging systems. Their space-saving design is invaluable in tightly packed vehicle architectures.

Similarly, the energy storage systems (ESS) market, projected to see a staggering CAGR of nearly 27%, requires safe and efficient connectors for battery racks and power conversion systems. The high-voltage ratings and robust safety features of SideWize are ideal for these applications, where reliability and operator protection are non-negotiable.

Data centers, the backbone of the digital economy, also stand to benefit. As power shelves become denser to support advanced computing, the need for efficient thermal management and compact power delivery becomes acute. The SideWize design helps optimize airflow and simplifies assembly, contributing to the overall efficiency and reliability of data center infrastructure.

A Strategic Play in a Competitive Field

By adding the Molex SideWize family, Heilind Electronics makes a strategic move to solidify its leadership in the high-power interconnect market. The decision reflects a deep understanding of the challenges facing its customer base of engineers and system designers. While established competitors like TE Connectivity and Amphenol offer a broad range of high-voltage solutions, the specific combination of a right-angle, rotatable, high-voltage, and finger-safe design gives the SideWize series a unique value proposition that Heilind can now leverage.

“Heilind is committed to providing the industry’s most comprehensive selection of high-power interconnect solutions,” noted Sal Baldo, NA Director of Supplier Relations at Heilind Electronics, in the original announcement. “Molex SideWize brings a unique combination of space savings, simplified installation, and safety features that directly address the challenges our customers face in high-voltage environments.”

This partnership reinforces the symbiotic relationship between component manufacturers and distributors. Molex develops the innovative technology, while Heilind provides the market access, technical support, and logistical infrastructure necessary to get those solutions into the hands of the engineers who need them. This move not only expands Heilind’s product catalog but also enhances its role as a value-added partner capable of providing cutting-edge components for the most demanding applications across industrial automation, EV infrastructure, and renewable energy.

Ultimately, the availability of advanced components like the Molex SideWize connectors through a major distributor like Heilind serves as an accelerator for innovation. By providing an off-the-shelf solution to complex power design problems, it empowers engineers to focus on system-level advancements, speeding the development and deployment of the next generation of electrified and automated technologies.
