SolarSpec panel-mount DC connectors and terminals from Molex

Molex Incorporated is expanding its range of SolarSpec products with the development of pin (male) and socket (female) panel-mount DC connectors. The IP67-sealed, SolarSpec panel- mount DC connectors, with internal locking and touch-proof design for enhanced safety, feature an innovation nut mechanism for simple assembly to the panel and provide a durable connection for cable attachment to solar inverters. Early samples of the new SolarSpec panel-mount DC Connectors will be unveiled by Molex at EU PV Sec in September, with full production quantities expected by the end of the year.

“The addition of the panel-mount DC Connector for solar inverters complements the

SolarSpec range, which now encompasses the junction box for silicon photovoltaic panels, crimp terminal DC connectors for direct attachment to solar junction boxes, field installations and photovoltaic grid wiring, and DC cable assemblies,” said Peter Commane, product manager, Molex. “Our in-house design and manufacture of the SolarSpec range ensures high-quality levels and reliability during service, whilst at the same time being cost-competitive. Customers will benefit from exclusive Molex design features, including moulded surface ribs and the industry’s lowest contact resistance when compared to equivalent DC connectors.” Offering exceptional efficiency, the contact resistance of the SolarSpec panel-mount DC

Range of Millimetre Wave connectors from Intelliconnect

Specialist manufacturer of Coaxial and Triaxial RF connectors, Intelliconnect, has announced the introduction of their new range of Millimetre Wave RF connectors. Millimetre Wave connectors are designed for use in 50 ohm systems and operate in the frequency ranges up to 110GHz, dependent upon series. The connectors are designed to have a low VSWR and return loss. The construction of these devices ensures that the body engages before the centre conductor and ensures a rugged and reliable mating interface. The interface is an air dielectric with the contact supported by a short glass or polymer bead. All Intelliconnect Millimetre Wave connectors can be configured to be terminated with flexible or semi-rigid cables. The series designation refers to the outer conductor diameter and generally the smaller the outer contact the

higher the maximum operating frequency. The connector family includes a 3.5mm diameter model with a maximum operating frequency of 34GHz, a 2.92mm diameter model with a maximum operating frequency of 45GHz, a 2.4mm diameter model with a maximum operating frequency of 50 GHz, 1.85mm diameter model with a maximum operating frequency of 65GHz and a 1.0mm diameter model with maximum operating frequency of 110GHz. All types are compatible with relevant standard Intelliconnect RF connectors.

As with all RF connectors supplied by Intelliconnect, these have been designed in accordance with the relevant connector Mil standard, have an operating temperature range of -65°C to +165°C and are manufactured in the UK and USA, using locally sourced components.

Connector remains below 0.5 milliohms. The contact can handle as much as 30.0A and accommodates

2.50mm2 and 4.00 to 6.00mm2 (14 AWG and 12 to 10 AWG) cable to meet a wide range of customer requirements. Polarised panel cut- outs help prevent rotation of the connectors and ensure no cross-assembly of male and female connectors on the panel.

The SolarSpec panel-mount DC Connectors have been designed to be both rugged and durable and are IP67-sealed to protect against the ingress of dust and water, and the housing body is resistant to UV and ozone damage. The touch-proof safety design protects installers and maintenance engineers from electrical current even during mating and decoupling operations. The connectors feature exclusive moulded surface ribs to allow secure gripping, especially while wearing work gloves.

The NEC 2008 (690.33) and NFPA 70 US

code-compliant solution developed by Molex is an innovative interlocking mechanism that prevents accidental and unauthorised decoupling of the connector during service in the field and provides for reliable connection and safe handling. For ease of assembly, a simple nut mechanism on the SolarSpec panel-mount DC Connector is tightened using a standard wrench, to secure onto the bulkhead of the inverter panel – also for additional security a Molex field service tool is required to disengage the latch when unplugging.

Lane Electronics | New spring finger family from TE Connectivity

As the demand for electronic devices continues to increase, so does the need for internal connections within these devices. In response to this growing trend, TE Connectivity (TE) is offering scalable spring fingers as well as a complete family of spring fingers to serve this surging need across all industries. TE's scalable spring fingers are available in

Flexible data cables for 10 Gigabit Ethernet applications

Harting has developed a new generation of flexible data cables which it says guarantee transmission in accordance with the IEEE 802.3an 10 GBase-D Ethernet standard. The new cables are designed to meet the demand for improved network components, which is rising rapidly with the constantly growing need for ever higher bandwidths. This trend fundamentally affects the development of the associated cabling, which traditionally precedes the introduction of the active network components by a significant period. The new cables satisfy the requirements of Category 6A according to IEC 6156-6 and are enclosed in proven industrial-grade cable sheaths. Both PVC and PUR sheaths are available. There are also two types with UL approval for the US and Canadian markets, plus a special outdoor version for use in external environments. The new flexible data cables feature a highly shielded PiMF (pairs in metal foil) design with optimum EMC characteristics for reliable data transmission. As a result, these cabling products

heights from 1.8mm to 3.4mm. "All these types can be mounted onto one single footprint, enabling the customer to swap the product easily when a design change is required," says Eric Himelright, director of product management, TE, "with the launch of scalable spring fingers, we are prepared to help our customers to reduce design cost as well as accelerate time to market and time to value." Another important feature of the scalable spring fingers is their preload function which nearly doubles the working area of a common spring finger and increases contact force by 0.2 N. The product also has a dimple on the contact, which helps enhance product reliability. The backward-bended tip prevents the product from hooking by removing the

sharp edge. On the back of the scalable spring

finger, there is a pick-and-place area that supports customer auto assembly processes. The holes at the bottom of the product increase soldering strength while reducing solder wicking issues.

Besides scalable spring fingers, TE offers a

product family of spring fingers in a range of styles and sizes. Currently, four styles are available. Their effective heights range from 0.3mm to 6.5mm with widths ranging from 0.8mm to 2.5mm. They all require very limited space on a PCB (printed circuit board) and accommodate soldering as well as pick and place using standard equipment.

Spring fingers, also known as shield fingers or universal ground contacts, have three main uses: They can be used for grounding between a device and a PCB; they provide shielding against vibration from motors, antennas, speakers, and microphones; and they can be used as signal connectors to transfer data as well as a connection for stacking applications between primary and secondary PCBs.

are ideally suited for use in automation, machinery and control systems applications. They can also be used for higher-level building infrastructures whenever there is a call for special features, such as robustness and chemical resistance. The AWG 26 wire is tested and released for all Harting RJ45 products.
