High density, lightweight signal connector specifically designed for applications where space and weight is at a premium for board to board interconnections. The HDLP series meets the requirement of space-constrained applications that require low mating force, a high number of mating cycles, low and stable contact resistance, and excellent fretting corrosion resistance.

This is the UAV launchers capable of launching the fixed-wing UAVs even on mountainous terrain, field, ships without sufficient runways to take off. It is designed to be the most powerful and easy to operate to take off the fixed-wing type UAVs of various specifications(Take-off weight, Take-off speed, and allowable G-force) into the air. It provides an interface that standardizes the shuttle for any type of unmanned aviation vehicle, and is easy to mount and to avoid take-off interference. A specially designed and manufactured hydraulic actuator is used to fully cope with the take-off weight of the aircraft, and a proprietary accumulator to allow a wide range of launch speed control. And multiple pulleys are equipped to ensure acceleration performance.
