SamTra International was established as a privately owned trading company in Seoul Korea on March 17, 1995, specialized in selling various type of special cables, connectors and cable assemblies for high reliable, high life time & mission-critical applications, and recently in supplying high performance electro-mechanical & optical components, such as air moving low noise level fans & blowers, and brushless motors and DC torque motors, actuators, slip rings, rotary joints, optical transceivers and ethernet switches for optical network communication in aero-mil applications.

With a peak torque of >200Nm / 1770 lbf-in and a rated torque of 80Nm / 708 lbf-in, the fully redundant DA 58-D is the strongest, electromechanical, fully integrated (actuator control electronics, position sensing, motor and drivetrain in one housing) actuator in the market. Besides the well-proven redundant RS 485 interface, the DA 58-D also features a redundant CAN bus interface. The DA 58-D has been developed for applications with the highest reliability demands. The redundant – two channel – design of the actuator allows continuous operation even if one of the two channels has failed. All major components such as the electric motors, control and communication electronics, and power supply are available twice (redundant). The actuator features a triple-redundant position sensor (2 out of 3 voting). Additionally there are several sensors integrated to provide diagnostic information such as current consumption, supply voltage levels and temperature readings. All major components of the actuator are continuously diagnosed by the microcontrollers of the actuator and its health status can be read via the redundant RS485 / CAN interface.

Developed by MPS Microsystems, the voice-coil nano-positioner unites a Lorentz-force motor, flexure guidance and on-board electronics inside a 65 × 60 × 38 mm envelope. Standard travel is 2.88 mm, extendable to 7 mm with the same coil, suiting microscope objectives, small mirrors and sensors that demand friction-free motion. Bidirectional repeatability stays within ±1 µm over a 360 µm stroke and ±2.5 µm across the full stroke. We can tailor mounting plates, objective clamps and cable exits to suit your specific requirements, ensuring that this voice-voil actuator can be integrated seamlessly into your system.

Primarily used in medium-sized and large satellites, it provides high torque performance and momentum conservation. By localizing the Control Moment Gyro controller, which had previously been imported for Korea’s domestic satellite industry, Lumir has gained a competitive advantage in both performance and cost.
