What’s New Tiny switch,many options Busy little heatsink
Knitter-switch’sMRS 8000 series rotary switch is claimed to be the smallest double-pole rotary switch currently
available.Measuring 9.9 by 9.9 by 4.5mmit suitsmedical devices, industrial automation control systems andmeasuring instruments.
Switches are available with
up to four positions in double- pole configuration and up to eight in single pole. Customers can specify horizontal or vertical shaft versions which can be flush or extended. A variety of control knobs are available.
Versions are offered for
surface mount or through-hole application. Specifications include: gold- plated contacts; -40 to 85/125o
C operating temperature range; and
20,000 step life. Standard switches are available via distribution, usually on next day
delivery.

Based on the science of honey bees, JaroThermal's newest honeycomb heatsink directs heat towards the outside,while producing a steady flowof cool air on the inside. Applications include a video cards,motherboards and networking applications. An adhesivemounted version eliminates the need formounting holes in the PCB.
Honeycomb heatsinks can be usedwith plastic or
metal/ceramic BGA packages, depending on the thermal interface material used. Also, the thin sizemakes it ideal for compact real estate applications. Lead-time runs 8 to 10-weeks ARO.

by 0.37mm, these devices can detect a magnetic field in either a horizontal or vertical direction. Compared with reed or Hall effect components, AMR sensors are said to have higher detection sensitivity, are more robust and offer a wider detection area.
Aimed at consumer electronics devices,
Murata has launched the AS-Mand AS-V series of anisotropic magneto resistance (AMR)
sensors.Measuring from 1.2 by 1.2
these sensors suit open/close detection applications for mobile phones, notebook PCs, white goods, industrial and security equipment.
The AS-Mseries provides horizontal sensing.Within the series, the AS-M15SAH-R Suppliesmeet Level V CEC
Powersolve has introduced the PSGE40-65 Series of 40 to 65Wdesk top power supplies whichmeet the latest CEC Level V requirements for Energy Saving with no load standby power consumption of <0.3mA.
Described as price competitive the
supplies feature universal AC input of 90 to 264 VAC and DC output voltages of 12, 15, 16, 18 and 24V. Output power ratings are 40, 60 and 65W.
48 | August 2011 Efficiency is >87 per centminimum. All
models feature LED power-on indicator and over-current and over-voltage protection. Safety approvals include UL/cUL60950, TUV/GS(EN60950), CB & CCC. EMI/EMC conforms to CISPR22’B’, FCC Part 15’B’ & EN55022’B’ and allmodels are Limited Power Source complying with IEC60950-1 sect 2.5.

and AS-M15KAH-R sensors feature a narrow range of sensitivity, from0.5 to 1.6mTwhile the AS-M15SA-R and AS-M15KA-R parts have awide range from0.5 to 2.2mT and are aimed at lower cost designs.
The AS-V series provides vertical
magnetic field detection, and is designed as a more cost effective replacement for Hall IC designs.
Both the AS-Mseries and AS-V series
have the same land compatibility as SOT23 and SON4 and suit reflow soldering.
