Miniaturization (Br.Eng.: Miniaturisation) is the trend to manufacture ever smaller mechanical, optical and electronic products and devices.
With the development of better hydrophones, the transistor and miniaturization, and the realisation that very low frequency sound was important, more effective acoustic sensors followed.
Often referred to as a Micro-D connector system, the connector is suited to a multitude of systems where weight, miniaturization or signal transmission integrity are paramount, such as missiles and their guidance systems, aerospace avionics, radars, shoulder-launched weapon systems, advanced soldier technology systems, military Global Positioning Systems, satellites, medical devices and down-hole drilling tools.
