Product details

The E3T-SL13 is a rectangular diffuse photoelectric sensor from Omron's E3T series, delivering a PNP light-on output over a 5 to 15 mm sensing range. Packaged in a compact 7×25×11 mm PBT housing with a 2 m prewired cable, it operates on 12–24 V DC and carries IP67 and CE. The output includes reverse polarity and short-circuit protection, making it a straightforward drop-in for tight sensing positions.

Comparing to the E3T-SL23

Same cable, same PNP output, same 2 m cable, same mounting — but the E3T-SL23 extends the max range to 30 mm. If your application needs the extra reach, order the SL23.

Mounting and Installation

Prewired 2 m cable, right-angle face, 7 mm wide, 1 msec response, ambient −13 to 131 °F. The mechanical fit matches the E3T-SL23.

Frequently asked questions

What is the closest functional second-source to the E3T-SL13?

The E3T-SL23 is the closest PNP peer; it shares the same dimensions, cable, output circuit, and light-on mode, but offers a 30 mm maximum sensing range versus 15 mm for the E3T-SL13. It is a direct mechanical and electrical interchange, so you can substitute without rewiring, just with a different range.

What are the key protection features on the E3T-SL13?

The sensor includes output reverse polarity protection, output short-circuit protection, and power supply reverse polarity protection.

Will the E3T-SL13 drop into a panel designed for the E3T-SL23 without rewiring?

Yes. Both sensors share the same 7×25×11 mm housing, same 2 m prewired cable, same PNP output, same light-on switching mode, and same IP67 rating. The only difference is the maximum sensing distance (15 mm vs 30 mm), so the physical fit and wiring are identical.

What compliance documentation does the E3T-SL13 carry?

The sensor bears CE marking. No RoHS, REACH, or UL certifications are listed in the record.
