The Omron E3T-SL12-M1TJ 0.3M is a compact reflective convergent photoelectric sensor from the E3T series, designed for detecting small objects at a fixed focal zone. Its sensing distance is adjustable between 5 mm and 15 mm, making it suited for close-range presence verification of parts or labels where background suppression is needed. Output is NPN open collector, dark-on operation — the transistor turns on when the light beam is interrupted. Supply voltage range is 12 V to 24 V, with a 1 ms response time. The housing is rated IP67, allowing use in wet or dusty industrial environments.

Product details
Frequently asked questions
What is the sensing distance and method?
It is a reflective convergent sensor with an adjustable sensing distance of 5 mm to 15 mm (0.197" to 0.591"). The beam converges at a focal point, allowing detection of small objects at close range with minimal background interference.
Can it replace an E3S-AR86 in a panel?
No. The E3S-AR86 is a retroreflective sensor with a 2 m range and PNP selectable light/dark-on output. The E3T-SL12-M1TJ is a convergent reflective NPN dark-on unit with a 15 mm maximum range — different mounting, wiring, and application.
