Technical Overview
The Omron E3Z-B87 is a compact photoelectric sensor with a built-in amplifier for transparent-object detection. It uses retro-reflective sensing and has a 0.5–2 m with E39-R1S reflector sensing range. This version has PNP output and M8 connector; the E3Z family uses a 12–24 V DC supply and IP67 enclosure.

Suggested applications
Engineering suggestions require suitability checks for your installation.
1. Transparent container detection
Detect clear bottles or transparent packages moving through a compact machine station.
Potential use
Pair the sensor with the specified reflector where required, and validate the target, alignment and 0.5–2 m with E39-R1S reflector range on the installed machine.
