The Ultimate Guide to Switching & Sensor Tech: Everything You Need to Succeed with Durakool

Modern power electronics demand more than just standard components. As systems for electric vehicles (EVs), renewable energy, and industrial automation become more complex, the hardware managing those loads must be exceptionally robust. Selecting the right switching and sensor technology is a critical decision that determines the safety, efficiency, and longevity of your final product.

At CTM Marketing, Inc., we specialize in connecting engineers with the world’s most reliable component manufacturers. As a premier technical sales agency serving the Rocky Mountain region, we are proud to represent Durakool, a global leader in switching and sensing solutions.

This guide explores the technical advantages of Durakool’s portfolio and explains how our "design-in" approach helps you optimize your next project.

Durakool: A Legacy of Technical Excellence

Durakool has been at the forefront of switching technology since the 1930s. What began as a specialist in mercury-based relays has evolved into a powerhouse of high-performance electromechanical and solid-state solutions. Today, Durakool is recognized for its ability to solve difficult switching challenges, particularly in high-voltage DC (HVDC) environments where traditional components often fail.

As manufacturers representatives, our goal at CTM is to ensure you have direct access to this expertise. We don't just sell parts; we understand the engineering behind them. Whether you are building an off-highway vehicle or a grid-scale battery storage system, Durakool provides the specialized hardware required for mission-critical performance.

High-Voltage DC Contactors: Powering the Future

The shift toward electrification is driving the need for contactors that can safely manage high-voltage DC loads. Durakool’s CHV series of ceramic HVDC contactors is designed specifically for these demanding applications.

Key Technical Specifications

• Voltage Ratings: Capable of switching up to 1,500 VDC.

• Current Capacity: Continuous current ratings up to 1,000 A.

• Breaking Capacity: Maximum breaking currents reaching up to 2,000 A.

• Arc Management: Utilizes advanced magnetic arc-blowout technology to extinguish arcs quickly, preventing contact damage.

Why Ceramic Matters

Traditional plastic-housed contactors often struggle with the heat and pressure generated during high-current DC switching. Durakool’s use of sealed, inert-gas-filled ceramic chambers ensures superior isolation and a much longer service life. This design prevents oxidation of the contacts, maintaining low contact resistance over thousands of cycles.

For engineers in the design-in phase, choosing a ceramic contactor early can prevent catastrophic failures during field testing. Learn more about how to navigate these early design choices in our Guide to Manufacturers Representatives.

Precision Sensing and Resistive Solutions

A complete power control system requires more than just switches. Monitoring temperature and managing feedback loops are equally important for system safety and efficiency. Durakool offers an integrated portfolio that includes platinum temperature (PT) sensors and power resistors.

PT Temperature Sensors

Durakool’s PT sensors are optimized for industrial and transport applications. They provide high accuracy and stability over a wide temperature range, making them ideal for:

• Battery pack thermal management.

• Industrial furnace control.

• Motor winding protection.

Power Resistors

From pre-charge resistors for EV inverters to discharge resistors for high-voltage capacitors, Durakool’s resistive elements are built to withstand high energy pulses without degradation.

By sourcing both switching and sensing components from a single principal, engineers can ensure better compatibility and streamlined procurement. As your component sales representative, CTM helps you synchronize these selections to reduce your bill of materials (BOM) complexity.

Solid-State and Mercury Relays: Industrial Durability

For applications requiring high-speed switching or extreme resistance to vibration, Durakool provides specialized relay solutions that go beyond standard electromechanical designs.

Solid-State Relays (SSRs)

Durakool SSRs are perfect for high-power AC switching in industrial heaters and motors. With no moving parts, they offer silent operation and an almost infinite electrical life. Typical capabilities include:

• Up to 660 VAC.

• Currents up to 100 A.

• Superior thermal management for continuous duty.

Mercury Relays

While less common in new consumer designs, mercury-wetted relays remain a gold standard for specific industrial applications. They offer completely silent operation, zero contact bounce, and exceptional resistance to shock. Durakool’s "self-healing" liquid contact medium makes these relays virtually immune to the wear and tear that affects dry-contact alternatives.
