New learning machines, for example, can offer hyperspectral surveillance, a scanning technology that uses sensors to identify objects in a spectral image. It can be used to monitor conditions and elements in the food production and agriculture industries and on satellites for defense purposes. In this process, the surveillance sensors receive analog data and rapidly convert it to differential digital signal information for transmission. Pressure transducers sense and send pulse modulation signals from MEMs chips to a central system. Laser focus and position controllers use pulsed phased-array control signals to pin-point optical information in the field.

These circuits require high density connectors and cable with special insulation to avoid cross talk from burst signals within the array. As artificial intelligence and neuromorphic processing systems grow, specially defined connectors and cables will be needed to handle each unique sensor within a system. This might include simultaneously collecting video imaging from cameras and analog information from speakers, detecting odors or radiation, measuring tactile data, and monitoring human health and well-being.
Man-to-machine learning systems may need a wired connection to perform sensitive procedures. Customized cabling and connectors can match unique and flexible machinery configurations.
Hybrid circuit sensors are designed to fit portable devices for data collection. Hybrid circuits often include a variety of circuit chips producing different signal types and speeds including digital, RF, and analog information. Micro and nano-sized connectors are used to pinpoint data and route it to central collection points while simultaneously delivering power to the sensors. The low-power hybrid circuits save space and weight, and fit well with micro-cable and connectors that are specifically designed to support signals from the various boards within the many hybrid circuits used in the machine or system.
Size and shape
Reducing the size and weight of the connector and cable system supports the placement of sensors and detectors in many places, including on mobile equipment. Each interconnect system is designed by first listing the electronic requirements of the circuit, how it will be used, and what environment it will be exposed to. Fortunately, many digital sensors can be served with one independent wire set of 32 AWG insulated wiring wrapped in differential signal pairs supported by a dedicated drain wire of similar size. Multiple differential signal sets fit easily into highly flexible shielded cable. Hybrid
connectors are easily formatted for the number of digital sets needed and can allow room for a power supply pair on one end of the connector insulator.
Connector shapes and mounting system formats are fit to match the form and function of the machining devices. For example, narrow jaw systems in robotic assembly often reach into narrow positions to achieve the last stage of assembly. Low profile rectangular connectors can be flat-mounted on the side of the robotic arm, saving space.
