Now available from Powell are compact and highly reliable Micro-D SMT connectors from Winchester
In stock at Powell Electronics, the supplier of connectors and more for high-rel applications including defence, aerospace and industrial, are the rugged Micro-D surface-mount connectors from Winchester. The devices provide a secure mechanical and electrical interface capable of withstanding high vibration, shock and other environmental stresses, making them ideal for the stringent demands of high-reliability electronic applications across aerospace, defense, medical and industrial sectors.
The connectors feature a compact rectangular form factor with multiple rows of precision-engineered supports space-constrained applications while maintaining signal integrity and long-term reliability. Designed for surface mount technology (SMT), the Micro-D connectors are soldered directly onto printed milliohms maximum for the contact interface, plus any additional resistance from solid leads depending on wire gauge, measured at 2.5A. The devices support a current rating of up to 3A and provide dielectric withstanding voltage of 600 VAC at sea level and 150 VAC at 70,000 feet, with leakage current limited to 1 mA. Insulation resistance is rated at a minimum of 5000 megohms at 500 VDC, ensuring reliable operation in demanding environments.

New application guide explains how high isolation, low leakage and long-term reliability support demanding mining systems
Pickering Electronics, a leading manufacturer of high-performance reed relays, has released a new application guide for engineers designing power and sensing systems for harsh mining environments. The guide, titled: ‘Reed Relays: The Logical Choice for Power & Signal Switching in Mining Applications’, explains why reed relays are well suited to high- and low-voltage switching and sensing applications where reliability, accuracy and low power consumption are critical.
such as conveyor belts, pumps, ventilation equipment and electrically-powered drills, while sensing and monitoring systems must continue to deliver accurate, repeatable measurements in challenging operating conditions. At the same time, higher voltages are increasingly being used to reduce power
These changing requirements mean that relays used in mining applications must be capable of handling demanding electrical environments without compromising measurement accuracy or long-term system reliability.

QS91 module utilizes low-cost single core
i.MX 91 to deliver capabilities for edge applications
Tiny SoM integrates NXP
i.MX 91 into high thermal industrial automation devices
Direct Insight, the UK-based technical systems integrator focused on system-on-module solutions, can now deliver and support development for the new QS91, featuring NXP’s
i.MX 91 applications for the next generation of Linux-based IoT and industrial applications. The QS91 is a tiny solderable computer module, measuring just 27x27mm, with 2.6mm total height in a single-sided assembly. Its QFN-style lead style design has a 1mm pitch with 100 pads – and in addition to providing EMC- compliant signal routing, the ground pad on the bottom side is also used for heat transfer, ensuring “With the spiralling cost of RAM due to the AI boom driving up the cost of embedded modules,” notes David Pashley, co-founder & Managing Director at Direct Insight, “Some applications need more cost- comparison to the
i.MX 93-based QS93. As the entry point into NXP’s
i.MX 9 series, the single-core
i.MX 91 applications processor delivers an optimised blend of security, features, and low-power performance to enable developers to quickly create new Linux-based IoT edge devices – but also provides the extensibility and ease of programming for applications to evolve over time.”

sensor designed to support users in their daily working routines display providing excellent readability and shows not only numerical values, but also fully written text. This makes menu navigation intuitive and especially for less experienced users or teams working in shifts. As a result, settings can be checked and adjusted quickly even from a distance, helping reduce set up time and machine downtime. A particularly practical feature is the new two
step limit teaching, which no longer requires manual adjustment of the emitted light. By simply pressing a button twice, the sensor reliably learns the switching threshold—even under challenging lighting faster and ensures stable detection of shiny, transparent, or very small components, providing reliable performance even in demanding industrial environments. The FX 250 also stands out with its extremely compact design. Its newly engineered cover requires an opening radius of only 30 millimeters, enabling installation in very restricted spaces and simplifying maintenance without the need to reposition surrounding components. This makes the sensor ideal for modern production machinery where space is limited and accessibility is crucial.
broader trend for increased use high voltage applications
recently completed production of a major optical link requirement for a leading energy distribution technologies is rising rapidly, particularly in high voltage (HV) applications – and the company continues to optimise its production to ensure it keeps pace. This has included the introduction of cobots to assist with labour-intensive repetitive and time-consuming tasks, increasing throughput and capacity up to 10x, while crucially maintaining quality and ensuring consistency. Director. “Mission-critical HV applications in power generation, transmission, distribution and supply infrastructure include reliable interference-resistant and electrically isolated sensing, monitoring, data transmission, communications and control. The dielectric construction and optical isolation of industrial high voltage breakdown, high bandwidth capabilities with low signal loss, immunity to electromagnetic interference and resistance to environmental factors.”

reducing system cost, complexity, and design time
heat sinks in many cases, shortening design time, improving manufacturability, and lowering total system cost.
“This is more than a product evolution—it’s a fundamental shift in how engineers can approach power supply design,” said Silvestro Fimiani, director of product marketing at Power Integrations. “For decades, designers have had to move to resonant topologies like LLC as power levels increased. With percent load—and easily beat European Energy-related Products (ErP) regulations at less than 50 mW
