Advertorials SCHURTER announces new current ratings for its
SMD fuse with 1500 SCHURTER’s Universal Modular fuse UMT-H offers a 1500 A breaking capacity at rated voltages of 277 VAC/250 VDC. This time-lag fuse provides now overcurrent and short circuit protection for applications up to 30 A.
Compact, high performance fuse is optimal for intrinsically safe applications
The "intrinsic safety" method is one of the most common techniques used for achieving safety protection with lower voltage or power equipment. This method restricts the available electrical and thermal energy in a system so that ignition of a hazardous atmosphere (such as explosive gas, dust, or electrical arcing) cannot occur. The UMT-H's high breaking capacity of 1500 A, plus the >10 mm spacing between end caps, combined with the ability to be impermeable to conformal coating makes the fuse suitable for use in such intrinsically safe applications.
The UMT-H fuse is available in a total of 24 rated currents between 160 mA and 30 A at voltages up to 277 VAC and 250 VDC. The UMT-H measures at 5.3 x 16 mm, which is a smaller alternative to the classic cylindrically-shaped cartridge fuses (e.g. 5 x 20 mm or 6.3 x 32 mm). The smaller footprint saves valuable board space, allowing for further downsizing of equipment. With its square design, the UMT-H is also suited for more cost-effective, automated assembly. The high breaking capacity fuse meets the IEC 60127- 7/1, UL 248-14 and CSA C22.2 standards along with its VDE and UL approvals. Additional applications include power supplies, electromobility, medical and telecommunication applications as well as 277 VAC utility-connected equipment.

Smiths Connectors launches its COTS Plus 2mm
Aurora connector series Reduces MTBF while increasing resistance to fretting
Smiths Connectors, a world-leading provider of high- performance interconnect solutions for the most demanding applications has announced the launch of its high performance Aurora Series, a COTS Plus 2mm hard metric connector for Compact PCI applications. This innovative connector range delivers a broad set of features and benefits to customers by addressing their high-reliability connectivity needs.
Most notably, the Aurora Series features enhanced gold plating with 1.27 m coverage on contact mating surfaces. This gold thickness provides significant durability, improved contact resistance stability (25% better than COTS after test cycle) and high resistance to fretting. This ultimately lowers total system cost by increasing Mean Time Between Failure (MTBF) by approximately 40%.
The Aurora Series is COTS compatible, allowing for reduced non-recurring costs due to common tooling and board layout. Additionally, Aurora is lubricant-free which reduces the occurrence of secondary contamination while offering electrical stability throughout the product’s life. Developed specifically for both telecom and aerospace applications, this Series is designed to performs in operating environments that feature extremely harsh conditions.

Tool-free 19in rack fastener replaces captive nuts
Rittal has introduced a fastener that replaces captive nuts when installing equipment in 19inch racks.
Attachment is by hand without tools, and it can be used with every enclosure in the Rittal product range straight away. It is available as a pre- assembled 1U support with three captive nuts, including centre attachment, to standard EIA 310.
Held in place by a thin spring in front of the mounting face, the product is designed for repeated dismantling and reuse.
“Integrating three captive nuts within the mounting profiles in just one click saves time, and nerves”, said Rittal product manager Clive Partridge.

Introducing Marl's new 612 Series Tri-colour LED panel lamp
Believed to be the smallest panel mounting device of this type of indicator in the world, Marl's new 612 Series Tri- colour features black anodised aluminium housing, a standard industrial mounting size of Ø6.35mm, and is sealed to IP67.
Marl's 612 Series Tri-colour has three colour coded terminal wires for ease of identification; Anode Red, Anode Green, and Common Cathode, Amber can be generated by powering red and green simultaneously, meaning a single indicator can be used for 3 different colours providing an efficient, space reducing indication solution.
Featuring all the benefits of our standard 612 Series, including smoked lens and wide viewing angle offering good on/off contrast ratio, outstanding reliability, and weatherproof, the 612 Series Tri-colour is suitable for portable equipment, high vibration applications, and status panel indication.
Samples and technical information are now available; get in touch to hear more about Marl's 612 Series Tri-colour

3M announces expansion to range of Novec Engineered Fluids for Precision Cleaning – now an even wider choice of effective
and sustainable options 3M, the science-based technology company, has announced an expansion to its range of Novec Engineered Fluids, with the aim of giving users even greater choice for the precision cleaning of metals and electronics components.
The latest addition to the range is Novec 73DE Engineered Fluid, designed for the more demanding types of metal cleaning applications. In common with other Novec Engineered Fluids, it has excellent health, safety and environmental properties in line with all current regulations, making it a safe and sustainable choice. It is also the lowest priced Novec Engineered Fluid, meeting demands for safe, heavy duty cleaning performance at a lower operating cost.
With its proven track record spanning two decades, the Novec Engineered Fluids Range is compatible with a wide
variety of materials. The range provides high-performing alternatives to regulated solvents that are traditionally used for cleaning, including n-propyl bromide (nPB), Trichlororethlyene (Trike) and Hydrofluorocarbons (HFCs).
These substances have been subject to increased regulatory scrutiny due to their high Global Warming Potential (GWP) for HFCs, and their CMR (Carcinogenic, Mutagenic or toxic to Reproduction) potential for nPB/Trike. Restrictions have been placed on their use including the Solvents Emissions Directive, the F-Gas Regulation and REACH regulations. Following a sunset date in April 2016, use of Trike is now banned and users of this chemical who have no prior authorisation could face significant fines. In September 2016 nPB was also included on the REACH draft authorisation list, which, if formalised could imply a sunset date and phase-down path similar to that of Trike. REACH has already deemed nPB as a Substance of Very High Concern (SVHC).
