Success Stories



Bipolar Hall Effect Sensors Utilised for Brushless DC Motors in Electronic-Controlled Communication Systems

Part Number: OMH3075S

A satellite actuation system required a combination of linear and rotary actuators to perform the necessary motion controlled functions. Our bi-polar Hall Effect sensor was utilised to determine the precise position and speed of the linear actuator shaft.



Robust Hall Effect Sensors Used in Control Systems for Mars Rover Robotic Arm

Part Number: OMH3040S

TT Electronics’ Hall-Effect sensors are key components in NASA’s Mars Rover. These sensors detect magnetic fields in motors that control the speed and movement of the satellite’s robotic arms.



RAD Capable Optically Coupled Isolator for Electrical Isolation Between Circuits

Part Number: HCC1001

The HCC1001 Optically Coupled Isolator is utilised to supply close-loop feedback signals by feeding analog information from the output to the input control circuit in a space-level Un-interruptible Power Supply (UPS).
