In This Issue    • 0.65 mm WLCSP Magnetic Switches    • Tradeshows   Ultraminiature 3.3-V WLCSP Magnetic Switch Sensors Following our launch of 1.5-volt WLCSP magnetic switch sensors last year, we are introducing 3.3-volt versions for logic power or battery supplies. The new versions also feature an extended temperature range to 125°C. The new parts provide unmatched spatial sensitivity and precision, and the 0.65 by 0.65 mm package makes them perfect for tight spaces and small mechanisms. Magnetic switches turn on when a magnetic field is applied and turn off when the field is removed. The applied field can be of either polarity, and the operate point is extremely stable over supply voltage and the full industrial temperature range. The open-drain output can sink up to 100 microamps. Key specifications of the new 3.3-volt versions include:    • Choice of magnetic operate points    • Omnipolar    • 2.4 to 4.2 supply voltage for power supply or battery operation    • Max. supply current 120 microamps at 3.6 V    • Full –40 to 125°C temperature range    • Ultraminiature 0.65 x 0.65 mm four-pad solder-bumped WLCSP Breakout Boards Available 0.8 x 0.4 inch (21 x 10 mm) breakout boards have pre-soldered WLCSP sensors, 0.1" headers, and 1 mm-pitch card-edge connectors.

NVE is planning to be at Space Tech Expo June 2 to 4 in Long Beach, California. NVE sensors and isolators such as the IL710H-3E high-rel isolator are inherently reliable and inherently radiation tolerant. NVE distributor Angst+Pfister will exhibit at the EPHJ tradeshow, June 3 to 6 in Geneva. The show's theme is "the world of high precision," and NVE offers the world's most precise magnetic switch sensors.
