Series Overview
Series Overview
E3Z is a widely installed OMRON rectangular photoelectric-sensor family covering diffuse-reflective, through-beam, retro-reflective and distance-set variants. Selection requires the sensing method, NPN/PNP output and connection type.
Part-number Structure & Selection Notes
Do not use the simple rule of "mantissa 1=NPN, 2=PNP" to judge E3Z. Taking the current common DC models as an example, D61/D62 is NPN, D81/D82 is PNP; T61/T62 is NPN, and T81/T82 is PNP. When selecting, you need to confirm the detection method, detection distance, output type, connection method and power supply at the same time. Common power supplies for standard DC types are 12–24VDC ±10%.

FAQ
Frequently Asked Questions
How do I confirm the complete part number for E3Z photoelectric sensor?
Do not use the simple rule of "mantissa 1=NPN, 2=PNP" to judge E3Z. Taking the current common DC models as an example, D61/D62 is NPN, D81/D82 is PNP; T61/T62 is NPN, and T81/T82 is PNP. When selecting, you need to confirm the detection method, detection distance, output type, connection method and power supply at the same time. Common power supplies for standard DC types are 12–24VDC ±10%.
What are the main differences between E3Z-D61 and E3Z-D62?
sensing distance: E3Z-D61 is approximately 100mm, E3Z-D62 is approximately 1m. Verify the complete ordering code and project conditions before selection or replacement; the series name alone is not sufficient.
Which specifications matter most when selecting E3Z photoelectric sensor?
Key specifications to verify are sensing method, sensing distance, output. Match them against the equipment nameplate, drawing or original model, and retain every suffix, option and regional code in the complete ordering reference.
Why is the complete part number required when requesting a quote for E3Z photoelectric sensor?
Models within E3Z photoelectric sensor may differ in electrical ratings, construction, interfaces or accessories. For example, E3Z-D61, E3Z-D62, E3Z-D81 are distinct configurations and cannot be interchanged on the series name alone. Using the complete part number substantially reduces mismatch risk.
Cannot find the complete part number?
Send the legacy part number, nameplate photo or application details and we will help identify the correct item.
