The QTRXL-MD-01A-S reflective sensor with an analog output enables precise detection of lines and objects. Thanks to its extended range and high sensitivity, it is used in robotic and automation projects. The JST SH connector allows easy integration, and the wide supply voltage range enables flexible use in 3.3 V and 5 V systems.

This module provides precise, galvanically isolated current measurement within a range of ±30 A and voltage up to 480 VRMS, providing RMS, instantaneous, and active, reactive, and apparent power readings. Equipped with an I²C interface, 4-pin JST SH connectors, and 2.54 mm pins, it allows for easy integration with Qwiic, STEMMA QT, and standard microcontrollers. Configuration stored in EEPROM allows for defining address and overload thresholds. The sensor offers three voltage measurement ranges (120 V - default, 240 V, 480 V RMS) and the ability to detect overvoltages. Built-in protection and low conduction resistance ensure safe and accurate measurements. The version comes with soldered screw terminals and a 240 Vrms jumper. Pololu 5412
