Overview
The E3Z-T61K is an Omron compact photoelectric sensor with built-in amplifier, rated for 15 m through-beam detection using an infrared LED at 870 nm. Current consumption sits at 35 mA max, and the unit weighs 0.12 kg — light enough for bracket mounting on moving machine arms.
How it compares
The E3Z-T61K reaches 15 m sensing distance, while the E3Z-R86 polarized retroreflective sibling covers 100 mm to 3 m — pick the T61K when the gap between emitter and receiver exceeds 3 m and a through-beam path is clear.
