Product description

The MTQ400 magnetorquers are aimed at applications in 6-12U CubeSats. Offering one of the highest energy efficiencies in the industry, combined with fine-grained dipole-moment strength control, it allows precise pointing and rapid de-saturation of any reaction wheels in the satellite.

Two models are available in the MTQ400 series: The standard MTQ400.50 and the lower profile MTQ400.40, perfectly suited for vertical installation in limited space.

With a unique boost-mode, these magnetorquers can be pushed up to higher magnetic dipole moments for short duration manoeuvres, through sacrificing some energy efficiency. In return however, these magnetorquers will offer the fastest de-tumbing of any satellite in this mass class, allowing the users to start their operations in the shortest amount of time. They furthermore feature an inherently safe, passive detumbling mode, which works without any external controller.
