Linear Regulators Deliver Constant LED Current In
Diodes Incorporated announced the introduction of the AL5890 linear constant-current regulator, developed to provide simple and more cost-effective solutions to
driving LED strings from an off-line or DC power supply.
Available in a range of packages, the small form-factor of the AL5890 makes it
ideal for any LED application where lower BoM cost and sizes are important. The
fully integrated design includes a power transistor, and it is available in 10 mA, 15
mA, 20 mA, 30 mA, and 40 mA variants. A single or multiple devices in parallel
can be used to source or sink enough current for long LED strings, with an overall
accuracy of less than ± 2.0 mA (typ), working over a wide ambient temperature
range of -40°C to +105°C.

New Side Bags For Portable Instrument Enclosures
OKW has added optional side bags to its CARRYTEC portable instrument
enclosures—making sensors, probes, and scanners readily available on the
move. Robust CARRYTEC enclosures are ideal for a wide range of applications
including medical and wellness, communications, data recording, agriculture,
and forest management.
The new zip-opening side bags are available as accessories in left- and right-hand configurations. Their smart design enables sensors and other cabled
equipment for remaining connected to the main instrument enclosures when
packed away—ready to use in an instant. The new side bags can be attached to
screw connections on the main enclosure. They are manufactured from molded
plastic and a hard-wearing textile fabric. Each bag features dual zips with corded
loops and orange toggles for swift access. An eyelet on the top of each case
enables a shoulder strap to be added.

Mechanical Sensor Detects Two Positions Within
One Single Product
Microprecision is introducing a new product for mechanical position
detection. The new MP600 series of mechanical sensors can detect two
positions within one single product. The distance within both positions
can be customized to the user’s application between 0.3 mm and 1.5 mm.
The fixed NC and NO contacts activate with no measurable hysteresis.
Repeatability is better than 5 µm and depending on cable selection,
the operational temperature can go from -40°C up to 130°C. The cable
termination can be supplied with a M12 connector.
This unique patented switching mechanism is designed for low voltage
applications up to 30 VDC. It is self-contained and can easily be inserted
in multiple forms and shapes of housings. The IP67 rated standard
housing sizes are M8 and M12 with a pin or ball plunger.

It is designed to tolerate
DC voltages of up to 400 V
and can be used in off-line
applications up to 230 VAC.
Because of its size and precision,
it can be used for home position
detection in any application with
The main CARRYTEC enclosures
feature a tough integrated handle
for easy portability.
