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

M12-style connectors
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.
