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.

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.
