TE Connectivity: Reliable Solutions for Aerospace, Automotive, and Industrial Applications

Over the years, platforms across various industries have grown significantly more automated and data-driven, leaning on the predictable transfer of power and data across systems. TE Connectivity is one such company that has built its portfolio around these exact needs, engineering connectors and sensing technologies that maintain performance whether exposed to the vacuum of space, the thermal cycling of an electric powertrain, or the harsh conditions of factory equipment. In this blog, we will examine two major product categories that TE Connectivity excels in, highlighting certain product lines that support aerospace, automotive, or industrial applications with consistent reliability.

High-Voltage Relays and Contactors

Aerospace, automotive, and industrial power systems all depend on high-voltage switching devices that can manage significant currents, maintain electrical isolation, and operate consistently under demanding current loads and environmental conditions. While the types of operations taken on in these environments vary, they still share a need for components that offer low contact resistance, robust dielectric strength, and protection against contamination.

TE Connectivity’s KILOVAC product families readily address such requirements, with some popular options including:

• KILOVAC MAP200 DC Contactors: A fitting choice for aerospace, electric vehicle, and industrial battery-system switching needs alike, these contactors feature:
• Hermetic sealing to prevent contamination from moisture or particulates.
• Continuous current capability up to 500 A across 12–900 VDC.
• Very low contact resistance of approximately 0.2 milliohms to limit heat generation and power loss.
• Dielectric withstand capability of roughly 2,200 Vrms for electrical isolation.
• A single-pole, single-throw (SPST) design, which remains open until energized. 
• Wide operating temperature range of –55 °C to 85 °C.
• KILOVAC EV-Series Contactors: These contactors were developed with electric and hybrid vehicle battery systems in mind, but they also suit industrial energy-storage platforms well. While there are many different specifications across the product line, they generally provide:
• High current-handling capability suitable for traction-battery switching and pre-charge circuits.
• Very low contact resistance for improved efficiency and thermal performance.
• Ratings for shock up to 30 g and vibration up to 20 g.
• Hermetically sealed designs that protect switching elements from humidity, dust, and shock.
• KILOVAC H-Series High-Voltage Relays: Used in aerospace power systems, satellite buses, and high-voltage industrial equipment, some shared characteristics across the H-Series relays include:
• Support for multi-kilovolt switching.
• Very low and stable contact resistance for efficient current flow.
• Lightweight, compact construction for space-constrained installations.
• Multiple coil voltages, such as 12 V, 26.5 V, and 115 V, supporting compatibility with many standard aerospace, defense, and industrial power rails.

Pressure and Position Sensors

Sensing technology is necessary to monitor pressure, control hydraulic and pneumatic actuation, verify fuel-system behavior, and provide precise feedback for motors and mechanical assemblies. TE Connectivity offers a broad sensor portfolio that leverages proprietary technologies and durable construction to present exacting measurements in harsh environments, such as the:

• MSP300 Pressure Transducer: A pressure sensor designed for hydraulic, pneumatic, and fuel-system monitoring, the MSP 300 features:
• Proprietary Microfused™ technology, using a micromachined silicon strain gauge that is molecularly fused to a stainless-steel pressure diaphragm. This creates a single, bonded structure with no adhesives, welds, or internal fluid, resulting in a highly stable and rugged sensing element.
• Pressure ranges from a few psi up to 10,000 psi.
• Standard 0–100 mV output, with optional amplified outputs.
• ±1% full-span accuracy.
• An operating temperature range of –20 °C to 85 °C.
• Compatibility with harsh fluids commonly found in aerospace, industrial, and automotive systems.
• Single-Coil (Reluctance) Resolver: This compact rotary position sensor can be used for aerospace actuators and control-surface mechanisms, as well as high-speed electric motors employed in automotive and industrial platforms. It is known to:
• Operate well from temperatures from –40 °C to 150 °C.
• Support rotational speeds up to 20,000 rpm.
• Have customizable cable and connector configurations for integration flexibility, as well as an optional integrated NTC temperature sensor.
• Present electrical accuracy of ±1°.
• Be compatible with oil or glycol environments.
• Through-Hole Position Sensors: These contactless angular or linear sensors are designed primarily for automotive transmissions, park-brake modules, and industrial actuators, displaying attributes like:
• PCB-free construction using an overmolded Hall-effect IC, which delivers both compact packaging and improved reliability in harsh environments.
• IP6K9 protection in many variants, enabling better resistance to high-pressure water spray, oil exposure, and road contaminants.
• Wide operating-temperature capability, such as a range of –40 °C to 140 °C for select platforms.
• Output options including analog, PWM, or SENT to promote compatibility with modern vehicle and industrial control architectures.
