Omron E2S-W24 1M Super-Compact Inductive Proximity Sensor

Model Identifier E2S-W24 1M
Official Part Number E2S-W24 1M
GTIN Standard NA

Technical Overview

The Omron E2S-W24 1M is a highly compact, block-style inductive proximity sensor engineered for industrial automation tasks requiring precise metal detection in constrained spaces. Encased in a miniature polyarylate resin housing measuring just 8 x 7.4 x 20 mm, it provides a stable sensing distance of 2.5 mm. Operating on a standard 12 to 24 VDC supply voltage, the sensor utilizes an NPN Normally Closed (NC) DC 3-wire configuration with a pre-wired 1-meter cable. Its impressive 1000 Hz switching frequency ensures high-speed response times, while the IP67 protection rating guarantees robust performance against dust and water ingress in demanding industrial environments.

Key Features

  • Super-compact rectangular body (8mm x 7.4mm x 20mm) for tight installation spaces

Industrial Applications

1. High-Speed Micro-Assembly Line Positioning

Utilized in high-speed robotic assembly arms and miniature conveyor diverters to confirm the exact presence and position of small metallic components.

Problem Solved

Space constraints in miniature assembly machinery often prevent the use of standard tubular M8 or M12 sensors. The ultra-compact 8 x 7.4 x 20 mm size and 1000 Hz switching frequency of the E2S-W24 allow for rapid, reliable detection in extremely tight mechanical clearances without missing high-speed target passes.

2. CNC Machine Tool Mechanism Monitoring

Integrated into CNC milling and lathing machines to monitor the status of mechanical fixtures, tool chucks, and verify the homing sequence of small automated turrets.

Problem Solved

Metal debris, coolant fluids, and oils rapidly degrade or blind optical sensors in machining environments. The IP67 rating, polyarylate resin housing, and inductive operating principle ensure continuous, contact-free operation despite cutting fluid splashing.

3. Automated Packaging Machinery Linear Actuator Homing

Deployed as an end-of-travel limit switch or homing sensor for pneumatically actuated linear slides in automated pharmaceutical and food packaging equipment.

Problem Solved

Traditional mechanical limit switches suffer from wear and tear over millions of high-impact cycles. The solid-state E2S-W24 proximity sensor eliminates mechanical failure and contact bounce, operating reliably on standard 12-24 VDC machine control power while fitting neatly on actuator profiles.
