To Your Basket Ordering Information Part Number: R21-IR05 Status: Discontinued Weight: 0.04 lbs An alternate version of the popular Sharp IR Rangers series. This detector uses a 2-wire serial interface to determine the presence of objects in a 10-80cm range. The range threshold is set by dial on the back of the sensor. This detector only takes readings when requested, not continuously, which offers much less current consumption in most designs.

This sensor has a variable resistor for setting a distance threshold. The interface is 4-wire and requires a JST connector which is included with each detector. Controlling the detector is done by lowering the input line, waiting for 28-56ms, and then checking for a logic 0 or 1 on the output line. One means no object is within the threshold distance, while zero means that there is an object present.

• Distance measuring type object sensor
• Impervious to color and reflectivity of reflected object
• High precision distance measurement through output of continuous measurement average value
• Low dissipation current at OFF-state (Typ. 0.3 uA)
