Product details

Integrator note

Omron E3T-SL12M is an NPN convergent-reflective sensor with a 5–15 mm sensing range on 50×50 mm white paper. Response time is 1 ms max, powered by 12–24 VDC (20 mA max consumption). The red LED (650 nm) gives a visible spot for alignment. Open-collector output handles up to 50 mA at 26.4 VDC, with residual voltage under 2 V at moderate load—enough for direct PLC input. Built-in protection covers reverse polarity, short-circuit, and mutual interference prevention, saving external diodes or fuses.

Frequently asked questions

What is the output type of the E3T-SL12M?

NPN open-collector, rated 50 mA max at 26.4 VDC. Residual voltage is 2 V max for load currents 10–50 mA, and 1 V max below 10 mA.

What is the sensing distance and method?

Convergent-reflective type, 5–15 mm on 50×50 mm white paper. Minimum detectable object is 0.15 mm diameter at 10 mm standoff.

What protection circuits does it include?

Power supply reverse polarity protection, control output reverse polarity protection, output short-circuit protection, and mutual interference prevention.
