An Earth Day reminder that virtually all NVE sensors and isolators are available in REACH, RoHS, and WEEE-compliant lead-free packages.
Most parts are also available in tin-lead versions for customers who need tin-lead reliability or solderability.

Magnetic Suit
April 1Make your own magnetic suit like the one worn by Jeremy Renner in Mission: Impossible Ghost Protocol.
You too can jump down a shaft and be caught by a magnetic field*.
Get a Spandex or Lycra bodysuit and a bunch of NVE magnets. We recommend** the part no. 12031 5/16" diameter by 1/8" sintered Type 5 ceramic disk magnet. If you prefer working in metric, use the 12216 6 mm diameter by 4 mm magnet.
Glue the magnets to the front of the bodysuit with Super Glue. Its important to put all the magnets with the same face (north or south) facing out, with the same magnetic polarity as the electromagnet at the bottom of the shaft.
Depending on your budget, you can determine magnetic polarity with either a gaussmeter or a Dollar Store compass.
Youll need about one magnet per square inch (one every six square centimeters for you metric folks). Depending on your surface area, that's about a thousand magnets.
Then steel your nerves and jump down the shaft.
What could go wrong?***
*Actually, it seems kind of dangerous to us. The math for a magnetic suit doesn't really work out.
** "Recommend" is a bit of an exaggeration.
***Quite a bit could go wrong.

IL700-Series Evaluation Board |
|
|
The new IL700-Series evaluation board lets you try a variety of NVEs flagship series of award-winning of IsoLoop Isolators.
The board has four IL700-Series Isolators in four package types:
IL716E (wide-body SOIC-16)
IL715-3E (narrow-body SOIC-16)
IL712-3E (SOIC-8)
IL710S-1E (MSOP-8)
IL700-Series Evaluation Board
IL700-Series Isolators use patented spintronic GiantMagnetoresistive (GMR) technology. The symmetric magnetic coupling barrier provides a typical propagation delay of only 10 ns and a pulse width distortion as low as 300 ps, the best of any isolator. And their real ceramic/ polymer barriers last pretty much forever.

Foolproof Interface IC
Short-circuit outputs, reverse power supplies, and thermal overload. Stuff happens April Fools day and year round.
But the unique NVE DB002-02 signal processing IC makes sensor systems virtually foolproof.
The eight-pin SOIC works with any current sourcing or CMOS/TTL output sensor, including, of course, NVEs AD1xx-Series magnetic switches. A typical circuit is illustrated below:
The DB002-02 provides a sourcing or sinking output up to 300 mA. Integrated transient protection makes the circuit especially useful for driving capacitive or inductive loads.
The LED is driven with 3 mA when the output is on. Shutdown delay after a short-circuit is set by the 1 nF capacitor. A larger capacitor can be used for a longer delay.
