The E3T-SL13M is a PNP convergent-reflective photoelectric sensor in Omron's ultracompact E3T series, built with the amplifier integrated into the housing. Sensing distance is 5 to 15 mm on a 50x50 mm white paper target, with a 1 ms response time for both operate and reset. Power supply is 12-24 VDC, consumption 20 mA max, and the open-collector output handles up to 50 mA at 26.4 VDC. The convergent beam helps ignore background objects beyond the rated distance, which is useful for position verification of small parts or transparent labels. Protection circuits cover reverse polarity on the power supply and output, output short-circuit, and mutual interference prevention — the latter allows side-by-side mounting without cross-talk.

Product details
Frequently asked questions
What is the output type and key specs?
The output is PNP open-collector, rated 50 mA max at 26.4 VDC. Supply voltage is 12-24 VDC, and the sensor draws 20 mA max. The sensing method is convergent-reflective with a range of 5 to 15 mm on white paper.
Will the E3Z-D61K work as a replacement for the E3T-SL13M?
No. The E3Z-D61K is a larger diffuse-reflective sensor with an infrared LED (860 nm) and a sensing range of 5 to 100 mm. The E3T-SL13M is an ultracompact convergent-reflective type with a 650 nm red LED. Panel cutouts, mounting dimensions, and optical behavior are different; rewiring and mechanical adaptation would be required.
