Cables and Connectors
Connectors for medical applications
A series of connectors can operate in temperatures from –270° to 200°C, making them suitable for medical applications ranging from cryogenic processes to imaging equipment, including CT scanners, MRI systems, and ultrasound machines. While many connectors contain silver-plating material, these connectors are designed with a combination of nickel and gold materials for use over a wide temperature range. The MDM-series micro-D, MDMA-series rectangular microminiature, and MTB1-series single in-line microminiature connectors feature a twist-pin contact system, which provides a secure base for the contact and exhibits better electrical and mechanical characteristics than traditional machined or stamped contacts, according to the company. The D*M and D*MA D-subminiature connectors are offered with coaxial, power, or high-voltage contacts. Employing nonoutgassing and nonmagnetic materials to eliminate distortion in imaging equipment, the connectors are configured for board-to-board, board-to-cable, and cable-to-cable functionality.
Intelligent connector system
A connector system with integrated firmware helps prevent misuse of medical devices. SmarTrack controls information embedded into a connector such as product identification, serial number tracking, stored and retrievable calibration data, and the number of times the device has been used. It also offers a method for embedding microprocessor intelligence into a connector. The intelligent connector system can be used on any of the company’s connectors to indicate whether the device is for one-time or multiple deployments. The system’s counter also makes it suitable for use when third parties refurbish or sterilize devices, guaranteeing quality and safety. The connector system comes with a data loading module, a graphical user interface, and an application guide
Similar to M12-style connectors, a line of connectors utilizes modified screw- and bayonet-locking mechanisms. Featuring a positive clicking mechanism that indicates when the connector is securely locked, the XS5 connectors also sport the Smartclick feature. This one-touch bayonet-locking system enables connection with a one-eighth turn. In addition to these features, the connectors mate with existing screw-type M12 connectors and offer ingress protection to the IP67 standard. The components provide better connections than screw-type connectors, according to the manufacturer.

Push-pull connectors and cable assemblies
Push-pull connectors offer medical device manufacturers a self-latching coupling mechanism with quick, reliable mating and vibration protection in a compact, high-density package. Offered in standard and water-protected versions, the push-pull JBX- and JKX-series connectors are available in a range of shell styles, materials, contact layouts, and configurations for outside-the-box quick-mate application. In addition to its selection of connectors, the company provides medical cable assemblies, from concept to final product. The supplier is equipped to handle small to high-volume runs, customization requests, overmolding, and cable assembly testing.

Utilizing industry-standard dual-density connectors in a metric-threaded 8-mm sealed unit to achieve remote device connections, a miniature interface block combines flexibility, serviceability, and high-density connectivity. By incorporating passive technology, the Multiple Interface Block (MIB) concentrates signals into one homerun cable, enabling the MIB to be remotely mounted with the devices and carry the signals back to the control system via a cable-out or quick-disconnect cable. Passive technology allows each point to be used as an input or output that can carry up to 2 A per contact with a 6-A total current. The dual-density connectors allow for two signals per remote device.
Modular plug and receptacle connector

Providing the interconnection room necessary to expand as design requirements change, a two-part modular plug and receptacle connector system has contacts that are laid out in four or five rows on a 2-mm pitch rather than in three rows on a 0.1-in. pitch. Part of the Tempus line, the CBC 20 connector system not only affords customers the ability to expand with each application size requirement, but it also allows engineers to manipulate large amounts of data at high speeds in the cable harnessing layout. The cable receptacles include all components needed to assemble finished cable ends. The four-row versions provide 4 × 6 and 4 × 12 contacts, while the five-row versions are available in 5 × 6- and 5 × 12-contact versions. The receptacles accommodate AWG 24 to 30 wire sizes with an insulation displacement contact, which offers quick termination without the need for wire stripping.
