Fool-proof connector system for medical system applications b
inder, the circular connector specialist manufacturer, has made available a fool-proof connector system designed for applications such as patient monitoring in the medical and home health care industry. Key selection criteria for specifying a connector system, particularly in the medical sector, is how often the connector will be mated and the environmental protection required when in use. The IP rating determines the degree of protection to dust and liquid and medical connectors are typically rated IP54 and above. Connectors are available with a variety of locking systems. Screw connectors provide the ultimate protection against accidental un-mating and have excellent IP performance but, on the downside, they are generally the most expensive type of connector, especially in metal versions. They are also not “convenient” for frequent mating cycles.
Push-pull connectors can also be expensive. However, the trend towards plastic versions has helped to reduce cost while snap-in and bayonet connectors provide quick and simple mating and are generally the lowest cost solution. To satisfy the need for a simple and reliable medical connector system, binder developed its Series 570 ELC (for Easy Locking Connector) specifically for use where the need for constant mating and un-mating is an important consideration. binder has designed the connector to be capable of more than 5000 mating cycles which is enough to
satisfy the operating requirements of many medical system applications. The ELC connector features an intuitive locking system that clicks together to ensure positive mating and protection against un-mating. It is also impossible to mis- mate the connector system as the mating position is defined by the profile shape of the mating area. Even un-mated, the female panel mount connector has been designed to provide protection against the ingress of liquids, water splash and accidental electrical contact and, when mated, the new ELC connector offers protection to IP54. Other important features include a PA66 plastic housing, 12 gold plated contacts rated at 2A, 150V. Wire size is 0.25mm² and operating temperature range is -25 C to +85 C.

Bayonet locking circular connectors with PCB contacts meet MIL-DTL-26482

nterconnection specialist distributor Lane Electronics has made available the Weald Electronics LMH series of bayonet coupling circular connectors with PCB contacts to allow these robust connectors to be mounted directly to printed circuit boards or flexi circuits.
Designed to meet the
requirements of MIL-DTL-26482, the LMH connectors are available in two shell styles. One is a fixed/receptacle square flange version (02A), the other is a fixed receptacle (jam nut) single hole mount version with an ‘O’ ring panel seal (07A). Lane Electronics offers these connectors with size #20 and #16 PCB contacts – sometimes called PCB tail contacts or spill contacts – with termination to PCBs or flex cable by a
long tail available in various lengths and diameters. As well as a wide variety of
standard PCB contacts, Lane also offers is also able to provide custom PCB contacts to suit specific applications. In its different forms, the LMH series comprises nine shell sizes and various styles with contact configurations from 2 to 61. The connector shells are manufactured from aluminium alloy and, as standard they feature a high resistance to corrosion thanks to an olive drab chromate conversion over a Zinc Cobalt, RoHS compliant plating finish. Other finishes including Cadmium, black Zinc Nickel and electroless Nickel are available on request.
Harwin introduces ready made cable assemblies for its datamate connectors
I
n order to provide customers with simple plug-and-play solutions, Harwin has now introduced a range of off- the-shelf cable assemblies to accompany its popular Datamate series of high reliability connector components. Supplied in single- or double-ended format, with a set cable length of 150mm (6 inches), these time-saving assemblies are certain to have considerable market appeal. They will give companies the quick and trouble-free access they need to the cabling without having to rely on their own in-house resources or make major investments into an expensive custom-built arrangement. The assemblies are available direct from stock, ready to
As well as meeting the
requirements of MIL-DTL-26482, the LMH series connectors are manufactured in accordance with IECQ-CECC spec BS/CECC 75201-003.

order from Mouser eliminating long lead times. They cover both signal (Datamate J-Tek/L-Tek) and power (Datamate Mix-Tek) configurations. Inherently cost effective, they are particularly well suited to one-off prototyping work or small-batch projects. Each assembly is produced in accordance with IPC-A- 620 standard concerning wire harnesses and cabling. They are given rigorous electrical testing and go through a comprehensive inspection process both during and after production. The cables used are PTFE insulated. The signal cables come with 24AWG gauge equipment wire, while the power cables are provided with either 10AWG or 12AWG gauge wire, with 40A or 20A current supported. With Datamate connector components at the heart of these assemblies, on-going interconnect robustness is always assured. Industry-leading resilience to shock (100G for 6ms), vibration (10G for 6 hours, 2 hours/axis) and extreme temperatures (-55°C to +125°C) are all exhibited. Furthermore, they can cope with up to 500 mating cycles. Consequently, the Harwin ready-made assemblies are rugged enough for deployment in the most challenging of application environments, including space, avionics, industrial drives/controls, robotics and motorsport. Outsourcing cable assemblies brings numerous operational benefits. The need for investment in new tooling, the establishment of extra manufacturing steps and the subsequent training of staff with no prior expertise can all be avoided.
