Technical Overview

The OMRON E2S-W23 1M is a super-compact, square-type inductive proximity sensor engineered for high-density industrial automation. Featuring a miniature 8x7.4x20mm polyarylate resin housing with a built-in amplifier, it provides highly stable unshielded side-view detection of ferrous metals up to 2.5mm away. The device features an NPN Normally Open (NO) DC 3-wire output and is connected via a 1-meter pre-wired cable. With an IP67 protection rating, an operational temperature range of -25°C to 70°C, and a high-speed 1 kHz response frequency, it excels in challenging factory environments where standard sensors cannot fit.

Key Features

  • Super-compact 8 x 7.4 x 20 mm square block design for tight automation installations [2.1].
  • Built-in amplifier delivering up to 2.5mm unshielded sensing range for ferrous metals.
  • High-speed detection capabilities with a 1 kHz maximum response frequency.
  • Reliable IP67-rated polyarylate resin housing withstands harsh industrial environments.
  • Pre-wired with a 1-meter cable for immediate integration into NPN/PLC control systems.
  • Includes built-in reverse polarity and surge protection circuits.

10-30 VDC operating range (12-24 VDC nominal) with an ultra-low maximum current consumption of 13 mA.

Industrial Applications

1. High-Speed Rotary Indexing Table Position Detection

Mounted close to a metal indexing disk to detect cam notches, allowing a PLC to determine rotational position for high-speed indexing tables.

Problem Solved

Mechanical limit switches suffer from wear at high speeds; this sensor's 1 kHz response frequency [2.2] allows fast, wear-free, contactless detection within tight machinery footprints.

2. Micro-Pneumatic Actuator End-of-Stroke Sensing

Positioned at the terminal ends of small pneumatic slide cylinders to confirm full extension or retraction of machine tooling.

Problem Solved

Standard proximity sensors are too bulky for micro-automation systems. The 8x7.4x20mm polyarylate housing fits into severely confined spaces while maintaining IP67 protection against factory fluids.

3. Robotic Gripper Jaw Confirmation

Integrated directly into the end-of-arm tooling (EOAT) on robotic pick-and-place arms to detect the presence of metal workpieces or verify jaw closure status.

Problem Solved

Excess weight and wiring volume hinder robotic speed. The E2S-W23's lightweight construction (approx. 10g) and flexible 1m pre-wired cable ensure minimal payload impact while securely feeding an NPN NO signal back to the controller.
