A complete guide to modular connectors
First developed in the 1960s and becoming more publicly available in the early 1970s, modular connectors were born out of necessity to provide a more simple, “modular” interconnection system for phone systems, data networks, and low-speed serial connections. During that same timeframe, the FCC developed a registration system for modular connectors, known as Registered Jacks […]
Getting one wire to do more, Part 4 – headphone wire as antenna
Using one wire in two very different roles is widely done, requiring some simple circuity and basic components. Using a headphone wire as an FM antenna The earliest portable AM/FM portable radios used two antennas: an internal long wire wound on a ferrite core for the lower-frequency AM band (550-1600 kHz), and a “whip” antenna […]
Liquid crystal polymers get an upgrade for high-speed signals
RF and high-speed digital signals have brought on the development of new liquid crystal polymer materials used in connectors, PCBs, and other interconnects. Liquid crystal polymers (LCPs) are experiencing a surge in demand resulting from high-speed communications technologies, particularly fine-pitch components such as high-frequency connectors, board-to-board connectors, and low-pass insulation supporters, or dipoles on active […]
Rectangular enclosures protect sensitive signs from external EMC signals
Advanced automation systems are required to continuously process large amounts of sensitive data/signals to operate machines while reducing errors. However, the data/signal on the manufacturing floor has been exposed to various problems associated with electromagnetic noise made from surrounding electrical or electric machines. When electromagnetic noise is added to electronic devices from the outside, unintended […]
Kit includes all tools needed for low-low, 50 Ω cable assemblies
The LMR-240 Kit from Times Microwave Systems packs everything needed for low-loss, 50-Ω cable assemblies into one box. The kit contains cables, interconnect components, lubricant to facilitate connector assembly, and even cable cutting tools, including the easy-to-use model CCT-03 tool for exposing and prepping cable center conductors with clean, burr-free cuts ideal for low-VSWR connector […]
Standard self-latching multipole connectors with alignment key
The LEMO B Series offers a modular, ergonomic, rugged and reliable circular multipole connector for applications needing quick and secure Push-Pull latching. They are suitable for test and measurement, instrumentation, medical devices, research and audio/video applications. The modular insert configurations include a wide range of high-density multi-pole or hybrid electrical contacts. Contacts can be of […]
Hi-Rel cable connectors available with rear panel mount options
To provide customers with greater choice and increase design flexibility, Harwin now offers rear panel mount cable connectors for both its 2mm-pitch Datamate and 1.25mm-pitch Gecko high-reliability (Hi-Rel) series. These will complement the company’s existing front panel mount solutions, broadening the scope of how connector housings are attached to an enclosure or panel. The clear […]
Safety clip for snap-in connectors secures high-stress applications
binder USA introduced a new accessory for its 620 and 720 Series miniature and subminiature connectors. New safety clips increase the security of circular connectors in applications where reliability is critical. The clips feature three snap-in lugs that produce an audible click to confirm when the connector is properly latched. For additional protection, these locking […]
RJ45 magnetic modules meet ethernet requirements
Daburn Electronics and its Polytron Devices division have announced a family of RJ45 magnetic integrated connector modules that can accommodate a variety of Ethernet-enabled devices. These RJ45 jack and connector modules integrate magnetics to protect against electromagnetic interference (EMI) and common mode signals, satisfying various data transmission requirements such as Power over Ethernet (PoE) networks, […]
