MT01A Compact Magnetorquer 1.25V to 5V
Up to 0.79 Am²
€ 1,100
With only 7.5 grams and 3.5 millimeters thickness, the MT01A Compact Magnetorquer is a vacuum core magnetic coil designed for ADCS control in cubesat mission from 1U to 3U that boast an impressive performance compared to its small footprint over the mass, power, and area budget of the spacecraft. Even with those small dimensions the MT01A is capable of greater magnetic moments, turn speeds and angular accelerations than comparable products on the market, yet the power usage is kept to a minimum: It can turn a 1U mass 90 degrees in 60 seconds using only 0.2 Watts at a LEO orbit of 500kms.
The greatest advantage of the MT01A is space saving: It can be easily affixed anywhere on your spacecraft using a minimal area and minimal thickness. Every coil is tested and qualified in our own facilities and shipped with full reports and packed with additional match connectors interfaces.
