A Practical Battery Powered RF (Wireless) Inductive Proximity Sensor System

RANCHO CUCAMONGA, Calif., Feb. 4, 2021 /PRNewswire/ -- Mercury United Electronics, Inc. announces the release of their complete Inductive Proximity Sensor System that allows operation of the sensor and the transmitter from just two +1.5V AA batteries with a typical transmission range around 70 feet, or 22 meters.

The typical total current draw for the combined Inductive Proximity Sensor and RF Transmitter module [MPRF-01] is 5 micro amps (uA) with no target motion, and only 200 micro amps (uA) at a target sense rate of 1 per minute. Using two Energizer L91 Ultimate Lithium (AA) batteries, which has an electrical charge capacity of about 3.3Amper hours (Ah) will provide about 16,000 hours of operating life at a 1 per minute sensing rate or about 1,600 hours of operating life at a 10 per minute sensing rate at 6 second intervals.
