Product details

Overview

The E3TST14 is an Omron E3T series through-beam photoelectric sensor set rated for 1 m sensing distance with a PNP Dark-On output, switching at 1 msec response time. It runs on 12-24V DC, detects a 2 mm diameter opaque object minimum, and is sealed to IP67 in a PBT rectangular body with a 2 m prewired cable.

Compared to the E3T-FT14, the E3TST14 doubles the sensing distance to 1 m versus 500 mm, but the minimum object size increases to 2 mm diameter from 1.3 mm — pick the E3TST14 when the application needs the longer range and can tolerate the larger target.

Frequently asked questions

What is the sensing distance of the Omron E3T-ST14?

Buyers need the real operating range vs the typical marketing figure to confirm fit before purchase.

Is the E3T-ST14 NPN or PNP output and light-on or dark-on?

Suffix -ST14 is ambiguous; PLC wiring compatibility depends on knowing output polarity and mode.

What is the E3T-ST14 response time and maximum switching frequency?

Determines whether the sensor can keep up with PLC high-speed counters or motion indexing.

How do you wire the Omron E3T-ST14 to a PLC input?

Panel builders need the 4-wire color code and sinking/sourcing diagram to avoid miswiring.

What is the difference between E3T-ST11, E3T-ST12 and E3T-ST14?

Spares managers and design engineers must confirm true drop-in interchangeability before substituting.

Is the Omron E3T-ST14 obsolete or still in production, and what is the recommended replacement?

Critical for lifecycle and last-time-buy planning; no FFF alternate is listed on the datasheet.
