Technical Overview

Ultra-slim 1m thru-beam sensor with 0.5ms response, IP67 rating, 12-24VDC input, and NPN output for precise high-speed object detection in tight spaces.

Key Features

  • Ultra-slim body with a thickness of 4.5 mm for side sensing type.
  • Through-beam sensing method with a 1-meter sensing range.
  • Fast response time of 0.5 ms or less.
  • IP67 ingress protection rating, suitable for harsh industrial environments.
  • Operates on a 12 to 24 V DC supply voltage.
  • Equipped with a red LED light source for easy beam alignment.
  • Features orange operation and green stability LED indicators.
  • NPN open-collector output (EX-19EA) or PNP output (EX-19EA-PN variant).
  • Minimum detectable object size of ø2 mm opaque object.
  • Up to 65% reduced power consumption compared to conventional sensors.
  • Incorporated inverter countermeasure circuit for improved extraneous light resistance.
  • Comes with a 2-meter long, 3-core (emitter: 2-core) cabtyre cable.

Ultra-slim design (4.5 mm thick for side sensing type) enables integration into extremely confined spaces, coupled with a high-speed 0.5ms response time for detecting fast-moving, small objects.

Industrial Applications

1. High-Speed Small Component Verification in Electronics Assembly

The EX-19EA's ultra-slim profile and fast 0.5 ms response time enable precise, high-speed detection of miniature components (down to ø2 mm) on conveyor belts in electronics manufacturing, ensuring correct part placement and count without impeding production flow.

Problem Solved

Ensuring accurate counting and presence verification of small, rapidly moving electronic components in automated assembly lines, where traditional sensors might be too large or too slow, leading to assembly errors or bottlenecks.

2. Precise Edge Guiding for Thin Film Processing

In film converting or packaging machinery, the EX-19EA provides highly accurate edge detection for thin film or paper webs. Its compact dimensions allow close mounting to rollers, and its 0.05 mm repeatability ensures consistent material alignment.

Problem Solved

Maintaining precise lateral alignment of sensitive, thin web materials to prevent wrinkling, tearing, or misregistration during high-speed processing. The sensor's small size and high repeatability are crucial for tight control.

3. Liquid Level Monitoring in Industrial Washing Systems

The IP67 rated EX-19EA can be submerged or exposed to water splashes to reliably detect liquid levels within transparent tanks or pipes in industrial washing and rinsing systems, preventing overflow or dry-run conditions.

Problem Solved

Providing robust and reliable liquid level sensing in wet and potentially harsh industrial washing environments where sensors are regularly exposed to water, requiring high ingress protection to prevent failure and ensure process integrity.
