## Description

Reflective photoelectric sensor for precise object detection in industrial applications, with PNP digital output and 12-24V power supply. Offers 3-20 cm distance adjustment and NO or NC selection for easy integration into automation. The integrated LED quickly indicates the operating status, and the compact housing and included metal support allow safe mounting on machines and production lines.
Distance sensor, Omron E3Z-D81 (PNP), designed for precise object detection in industrial applications. The integrated LED indicator clearly shows the operating status, making it easier to monitor activity in real time. Its robust housing and compact size make it easy to integrate into production lines, packaging systems, or automated handling equipment.
The sensor features a trimmer for distance adjustment and another for setting the normal state (Normally Open or Normally Closed).
The sensor may come with a metal mounting base for fixing it in the desired location; its presence may vary depending on the batch.
The sensor has a PNP (sourcing) output, meaning the sensor output supplies voltage (VCC) when active. Current flows from the sensor to the load, then to GND.
