Mixed Signal Power Micro-Ds Reduce Size, Weight in Miniature Electronics

Omnetics' Micro-D connectors combine two functions into a one plug-in contact system.

MINNEAPOLIS, March 31, 2015 -- Designers are finding that connecting both signal and power systems into and out of their equipment is taking a large portion of their size and weight allowance. Smaller cabling and connectors are now being offered that solve that problem. We see a rise in the use of combined power and signal being routed to and from instruments within one cable. Mixed-pin design connectors are able to handle a combination of higher power supply voltages and currents but also include much smaller pins, sockets and wiring for the remaining signals. Cabling is available that can offer combinations of wire sizes, group shielding and drain wires that may be needed. See: http://www.omnetics.com/Micro-D


As higher speed electronics begin to dominate the design world, we see surveillance systems, probes, detectors and new Ethernet systems demanding a combination of power and higher speed differential signal processing in one interconnection unit. Unmanned vehicles often require assembly and disassembly in the field for transfer. Using only one ruggedized Micro-d connector offers quick and easy assembly. Down-hole electronics need only one power source and a number of signal processing systems. The Micro-d hybrid circuit easily fits down inside the drilling system and provides the ruggedized high temperature performance needed. Robotics systems have motors out at the end-of-arm systems that need power and use tactile sensors to operate correctly. The multiple-signal, one-connector system solves both size and weight problems.

Omnetics Micro-D shells offer a standard format the designer is familiar with and achieves the rugged miniaturization needs of this new era. Omnetics' hybrid connector combination eliminates a need for two connectors and offers both higher speed digital and power within one plug-in unit. The power contacts can handle size 20 to 24 AWG wire and is suitable for 7 Amps plus, while signal contacts can handle up to 3 Amps. Shell size is adjustable to pin count and board termination formats include right-angle and straight thru-hole mounting. Differential signal pairs will need high speed cabling that can also be accommodated. Omnetics uses military test certified components on Micro-D connectors that have been QPL qualified at Mil-DTL-83513, the reliability and quality is assured. The wired power contact is an insertable/removable type contact which can be optionally supplied for customer termination, if needed. Connector shells can be of the standard jack-screw mating style or use the new Latching Micro-D style. Both latching systems exceed military locking tests. When a new power and pin contact format is requested, Omnetics' design staff will rapidly make solid-models of your product concept and email them to you. Fast turn design completion and approval will greatly reduce time to prototype and first production products.

ST Robotics Develops the Workspace Sentry for Collaborative Robotics

The ST Robotics Workspace Sentry robot and area safety system are based on a small module that sends an infrared beam across the workspace. If the user puts his hand (or any other object) in the workspace, the robot stops using programmable emergency deceleration. Each module has three beams at different angles and the distance a beam reaches is adjustable. Two or more modules can be daisy chained to watch a wider area. "A robot that is tuned to stop on impact may not be safe. Robots where the trip torque can be set at low thresholds are too slow for any practical industrial application. The best system is where the work area has proximity detectors so the robot stops before impact and that is the approach ST Robotics has taken," states President and CEO of ST Robotics David Sands.
