The MAXREFDES27# is a tiny IO-Link proximity sensor with an IR receiver, matching IR LED driver, IO-Link transceiver, and energy-efficient step-down converter all on an 8.2mm x 31.5mm printed circuit (PC) board. Maxim Integrated and Technologie Management Gruppe Technologie und Engineering (TMG TE) collaborated in designing the MAXREFDES27# as an IO-Link version 1.1/1.0 compliant proximity sensor…

The LDC0851EVM (Evaluation Module) demonstrates the use of inductive sensing technology to accurately detect the presence of a conductive target object passing a fixed threshold. The module includes a perforated and interchangeable 4-layer PCB where both the sensing coil as well as the reference coil are stacked for reduced system size.

Alarm will sound at 6.0V for 2 cells and 9.0V for the 3 cell configuration. Current draw: 5.5mA @ 7.4V (alarm off) : 29mA at 6.0V (alarm on). Simple ‘dead bug’ construction weight was 2.9 grams.

The AS3935 Franklin Lightning Sensor™ Demoboard is a fully operational handheld lightning sensor which is able to estimate the distance to the head of upcoming storms. Lightning events will trigger the AS3935 demo kit and will be shown on the LCD. The display will show detail information about approaching and departing storms and the actual distance to the head of the storm. The buzzer provides a…
