Robotic Connectivity Products

robotic connectors from OmneticsOmnetics Connector Corporation’s PZN Polarized Nano Connectors are amongst the smallest, lightest-weight, and lowest-profile board-to-cable connectors available in the industry. Designed to deliver high-reliability, high-signal-integrity performance in applications subject to shock and vibration, the series features an ultraminiature package that’s available in a variety of wired and board-mount options; a ruggedized, nanominiature pin-to-socket system with 4–24 gold-plated copper alloy contacts (even numbers only) a 0.025” (0.64mm) pitch ideally suited for high-density circuit modules; and LCP insulators designed to hold one row of pins and one row of sockets, which effectively polarizes the connector without the additional space required for guide pins. Surface-mount PZN connectors are available with horizontal (AA), vertical (VV), and straight through-hole terminations. Pre-wired and wired cable variants are available with discrete wire, twisted wire, cable, multiple-wire-type terminations and 30, 32 (standard), or 34AWG wire in standard (18”) or custom lengths. They are also available with standard color coding (10 repeating colors per MIL-STD-681) or other wire colors. The series is rated for 1A per contact, 250VAC RMS at sea level, and 200 mating cycles in operating temperatures spanning -55°C to 125°C. High-temperature (200°C) and COTS versions are also available. Ideal applications include routing signals from a wide range of evolving devices in the micro and sensor industry and interfacing with standard PCBs for data processing. In robotics systems, they can be used to connect miniature linear actuators, route sense and/or drive signals to and from pneumatic actuators, respond to piezoelectric detectors, and drive hydraulic pistons and gears. For instance, at least one brand of prosthetic hands uses PZN connectors to facilitate finger bending and clenching.

Robotic cabling solution from Phoenix ContactPhoenix Contact’s cabling solutions for robots and drag chains are especially designed to be permanently flexible. These cables ruggedly withstand continuous mechanical strain and welding sparks and exhibit extreme durability of more than 10 million bending and torsion cycles to ensure high-reliability, long-lifetime performance in high-stress applications. Ideally suited for use as sensor and actuator cabling on moving machine parts, these special, highly flexible and resilient cables are also available with a range of corresponding, proven-rugged cable rings, assembled cables, and distributor boxes. Phoenix Contact also offers a sensor/actuator cable configurator to provide easy access to optimal application-specific solutions.

Robotic connectors from RosenbergerRosenberger’s RoPD Connectors are magnetic self-mating connectors that enable easy handling and quick connections, ensure proper mating with no risk of canting in even hard-to-reach locations, and support safe, reliable power and data transmission in light electric vehicles including pedelecs, e-bikes, e-scooters, and wheelchairs and unmanned ground vehicles including mobile robots and drones. They also have a breakaway function that facilitates both quick and easy deliberate unmating and automatic unmating should the plug or cable be subjected to acute tensile force, be it accidental or intentional, to prevent potential injury to users, the connectors, and connected devices. RoPD connectors are particularly well suited for data communication, power transmission up to 60V, and current loads up to 40A and feature a high-tolerance pin and socket design that supports high mating cycles in applications like battery charging, where frequent connections and disconnections are required. Their four data contacts and two power transmission pins make hot-plugging capabilities unnecessary, as the data contacts only activate the power upon connection, and the four data contacts can also be used as a BUS system with an additional supply voltage. Other RoPD benefits include robust water-, shock-, and -vibration-proof performance, UV resistance, zero-force self-located mating, a shallow mounting depth, and reliable contact pressure. Cable assemblies rated for 10A, 25A, 30A, and 40A, 60VDC, IP67 protection, and more than 2,500 mating cycles in operating temperatures extending from -40C to +65C are available equipped with straight or right-angle RoPD charging connector jacks, round or square RoPD battery panel plugs, flexibly seated RoPD slide-in panel jacks, PCB connectors, and protective caps. Versions of the RoPD system are also available for EnergyBus applications.

Mill-Max Omniball contacts for roboticsMill-Max’s new Omniball spring-loaded contacts are specifically designed for sliding and rotational connections. The new spring-loaded, surface-mount contacts have an innovative, patent-pending design with a gold-plated rolling-ball interface in place of a traditional plunger to allow mating components to engage in lateral, rotational, and angular alignments (vs. traditional axial or vertical alignments) and ensure optimal electrical, mechanical, and structural reliability. When engaged, the ball compresses and rolls, allowing the mating surfaces to make contact and smoothly slide parallel to each other. Spring force maintains consistent electrical contact between the mating surfaces while the rolling action alleviates connector damage concerns common to traditional plunger-style spring pins in these types of applications, including binding, premature wearing, and structural failure. The new Omniball contacts have a maximum stroke of 0.030” (0.762mm) and an overall height of 0.266” (6.67mm) and have been tested to 1,000,000 compression and rolling cycles at half-stroke while still meeting specifications for maximum contact resistance of 20mΩ, 3.5A rated current, and 55g spring force at mid-stroke (0.015” or 0.381mm). Ideal applications for the series include any application that involves sliding or rotating connections, such as twist-and-lock cable connectors, smart-lens camera connectors, and rugged and IP-rated connectors with quarter-turn and threaded mating mechanisms, as well as robotics, docking stations, quick connects, and blind-mating applications. The new contacts are available as both individual pins and in a four-pin circular connector that’s especially well-suited for round cable connector applications and can be shipped in tubes or tape and reel packaging. Custom designs are also available upon request.
