‘World’s smallest’ 5-10W power supplies XP Power has launched what it
believes are the world’s smallest five and ten Watt single output AC-DC power supplies. At just 25.4 x 25.4 x 15.24mm, the 5W ECE05 series of encapsulated board mount power supplies are suitable for end-product designs where board space is at a premium and a low power high power den- sity supply is required. The ECE10 series provides 10W output from just 38.1 x 25.4 x 15.24mm. Both series comprise seven models covering nominal output voltages from +3.3 to +48VDC, all from a wide universal input of 85-264VAC with Class II construction, meaning no earth or ground connection is required. In addition, all models meet the no-load power consumption limit of less than 0.3W and average efficiency limits. A peak load capability permits an output of up to 130% of nominal output power to cater for short-term high power

loads without the need to specify a higher rated power module. The ECE05/10 modules are convection cooled and operate without the need for additional heat sinking or forced airflow. Operating temperature is across the range of -25 to +70˚C, with no derating until +50˚C. XP Power T: 0118 984 5515

New to AVX Corporation’s 9159 Series of SMT connectors are the IDC wire-to-board plug and socket connectors. These are said to facilitate the easy, reliable and cost-effective termination of 22- 24AWG discrete or cabled power and signal wires into standard 9159 Series two-piece connector systems, maximising their flexi- bility by providing them with wire-to-board capabilities. The connectors feature wire assembly support blocks that enable the single-step termination of two through six wires with any standard bench-top press, gold- plated BeCu contact systems for high reliability in harsh environ- ments, and integrally moulded latches. They can be used in temperatures ranging from -40˚C to +125˚C, and provide both through (daisy-chain) and wire- stop termination options. Designed to solve packaging issues in the broad industrial and
Waterproof stainless steel motor range
New from Regal are the Leeson Extreme Duck stainless steel washdown motors, which meet the requirements of the food and beverage, pharmaceu- tical and packaging industries. With the range, which meets or exceeds (IE2) efficiency standards, advanced thermal manage- ment has allowed the traditional array of cooling fins to be designed out, leaving a smooth, clean, outer surface free of potential dirt and bacteria traps. Through-bolts have also been eliminated and the design team has developed a screw-on conduit box cover to further reduce the potential for trapping contaminants. O-ring sealed open- ings are provided on the conduit box covers and rotor/cartridge covers.
In addition, Leeson’s Hydro Sealed System ‘HS2’ protects from the outside-in by reducing the points of entry for contaminants and eliminating the need for drain plugs and breathers. The Q-Car rotor/cartridge seal system gives quick access to the interior of the motor, should the need arise. Additional features include a Protech bearing isolator used for the output shaft seal and a rigid cast base, enabling their use in demanding applications. All are supplied with high performance inverter rated insulation as standard and enclosure protection is IP65.
The range covers 3-phase, 208-230/460V requirements at a 0.25 to 2kW power rating, with other variants from the range such as White Duck and Premium Stainless Duck available for higher power ratings and other IEC frame sizes, including a brake motor version. The base can be C-face or C-face less. Regal UK/Rotor (UK)

New from Sanyo Denki is the SH2141 stepper motors, which weigh just 28g and have a 14mm frame size and a 30mm long body. Available in the UK from EAO, the stepper motors allow precise control of small control elements and feature a 6.5mNm torque. With a single shaft and dual shaft version, the products are

solid-state lighting markets, the miniature IDC plug and socket connectors carry up to 5A per contact, can function at up to 125˚C for extended periods, and enable co-planar PCB mating. Other suitable applications include: portable commercial and industrial handheld terminals, scanners, and meters; medical devices, such as patient monitor- ing and drug-dispending devices; and industrial electronic modules and controls.

Adhesives withstand 120˚C temperatures
The Loctite 401, 406 and 454 adhe- sives are now temperature resistant up to 120˚C.
Capable of joining almost any mater- ial in as little as two seconds, these adhesives are clean and easy to apply. Loctite 401 all-purpose instant adhesive is suitable for rubber, plastics,
metals and porous materials such as wood, paper, cork and leather. It is also ideal for smooth, acidic sub- strates – for example, galvanized or chromed components. The 406 adhe- sive is said to be particularly effective at bonding polyethylene, polypropylene and PTFE after pre-treatment with Loctite 770 Polyolefin Primer. For applications where non-dripping
is a pre-requisite, the improved Loctite 454 general purpose gel is recom- mended. This can be used on vertical or overhead surfaces, and for bonding a wide range of dissimilar materials where large gaps are present. Henkel T: 01442 278000 Enter 248
