Model Identifier E2S-W25 1M
Official Part Number E2S-W25 1M
GTIN Standard NA

Technical Overview

The Omron E2S-W25 1M is an ultra-compact inductive proximity sensor engineered for high-speed industrial automation. Housed in a durable polyarylate resin rectangular block (8mm x 7.4mm x 20mm), it features top/side-view sensing with a maximum detection distance of 2.5 mm. It utilizes a DC 3-wire circuit with a PNP open collector and Normally Open (NO) operating mode. Operating reliably on a 10 to 30 VDC supply, it offers an exceptionally fast 1 kHz response frequency, making it ideal for tracking rapidly moving metallic components. Equipped with a pre-wired 1-meter cable and boasting an IP67 rating, it is built to withstand harsh, constrained environments.

Key Features

  • Ultra-compact rectangular block body measuring only 8 x 7.4 x 20 mm
  • 2.5 mm inductive sensing distance for metallic objects
  • DC 3-wire configuration with PNP Normally Open (NO) output
  • High switching frequency of 1,000 Hz (1 kHz) for rapid processes
  • IP67 degree of protection for resistance against dust and liquids
  • Pre-wired with 1-meter cable terminated with bare flying leads
  • Durable polyarylate resin housing construction
  • Built-in output reverse polarity protection and surge suppressor

Ultra-compact 8 x 7.4 x 20 mm footprint combined with a rapid 1 kHz switching frequency, enabling reliable metal detection in extreme space-constrained, high-speed applications.
