High-Voltage Latching Contactor for UAVs & Unmanned Systems

The contactor features high voltage isolation, small size and weight, and reduced power consumption By Mike Ball / 13 Jul 2022

TE Connectivity KILOVAC contactorTE Connectivity has launched a new configuration of its KILOVAC CAP120R contactor, designed for UAVs (unmanned aerial vehicles), robotics and other commercial, military and aerospace applications requiring lightweight latching coils and reduced power consumption. The new version of the 150-amp DC contactor now features a high-voltage latching configuration, as well as single pole, hermetically sealed auxiliary contacts with a latching actuator mechanism, allowing for low-power consumption uses.

The efficient design makes TE’s KILOVAC CAP120R contactor a reliable solution for power distribution, energy storage and battery systems and satisfies the demand for reliability in harsh environments for long-lasting systems due to the contactor’s lightweight design, which can withstand high break levels —1,000 A at 400 VDC and 600 A at 600 VDC. The contactor also allows versatile installation through bidirectional load switching, and the main contacts are not polarity sensitive.

TE’s KILOVAC CAP120R contactor is designed to withstand harsh environments, with specifications including:

Temperature range: -40°C to +85°C
Voltage maximum: 600 Vdc
Mechanical life (Min): 100,000 cycles
Weight (Nominal): 0.14 kg

Earle Alldredge, product manager for TE’s Aerospace, Defense and Marine division, commented: “This solution was designed in response to a key industry need for higher voltage isolation, small size and weight and reduced power consumption. With this in mind, the TE KILOVAC CAP120R contactor delivers a highly versatile solution that is extremely small in size and lightweight relative to its voltage and current ratings, while still able to manage high voltages and high current systems for airborne application designs.”
