Frequently Asked Questions
What is the OMRON E3Z-D82?
It is an E3Z series compact diffuse-reflective photoelectric sensor with an infrared light source, PNP output and a maximum specified sensing distance of 1 m under standard test conditions.
What is the sensing distance?
The rated sensing distance is 1 m when detecting a 300 × 300 mm white paper target. Actual detection performance varies with the target surface, color, size and installation.
Is the E3Z-D82 an NPN or PNP sensor?
The E3Z-D82 uses a PNP open collector output. The corresponding E3Z-D62 is an NPN output variant.
What supply voltage does it require?
OMRON specifies 12 to 24 VDC ±10%, with supply ripple not exceeding 10% peak-to-peak.
What is the maximum output load current?
The control output is rated for a maximum load current of 100 mA, with a maximum load supply voltage of 26.4 VDC.
Can Light-ON and Dark-ON be selected?
Yes. The E3Z-D82 supports selectable Light-ON and Dark-ON operation.
What is the response time?
The manufacturer specifies 1 ms maximum for both operation and reset.
What type of light source does the sensor use?
It uses an infrared LED with a nominal wavelength of 860 nm.
How long is the connection cable?
The standard pre-wired E3Z-D82 is listed with a 2 m cable, while other cable-length variants are available. Verify the supplied product's complete ordering designation.
Is the E3Z-D82 waterproof?
The sensor has an IEC IP67 enclosure protection rating. Installation must comply with manufacturer instructions, and IP67 does not imply suitability for every washdown or chemical exposure condition.
Can E3Z-D82 replace E3Z-D62?
Do not assume direct interchangeability. The E3Z-D82 has a PNP output, while E3Z-D62 has an NPN output. The controller input configuration and wiring must be compatible.
What should be checked before ordering?
Confirm model E3Z-D82, PNP output, diffuse-reflective sensing method, 1 m rated sensing distance, 12–24 VDC supply, cable length, Light-ON/Dark-ON setting, mounting arrangement and environmental requirements.
