Technical Overview

The OMRON E3T-FD12 2M is an ultracompact, ultrathin photoelectric sensor featuring a built-in amplifier and a diffuse-reflective sensing method. Enclosed in a rugged Polybutylene Terephthalate (PBT) housing with an IP67 rating, it delivers precise object detection with a sensing range of 5 to 30 mm. It utilizes a red LED light source (650 nm) and operates in a Dark-ON mode, outputting an NPN signal (26.4 VDC max, 50 mA max). The sensor comes pre-wired with a 2-meter cable and features M2 mounting, making it ideal for tight, space-constrained industrial automation environments requiring high-speed responses (1 ms max).

Key Features

  • Ultracompact and flat-form ultrathin PBT housing for space-constrained mounting.
  • Diffuse-reflective sensing method with a 5 to 30 mm detection distance.
  • Dark-ON operation mode with NPN open collector output.
  • Built-in amplifier eliminates the need for external processing units.
  • High-speed 1 ms maximum response time for rapid automated lines.
  • IP67 degree of protection suitable for demanding industrial conditions.
  • Pre-wired with a 2-meter cable with bare end flying leads for direct integration.

Industrial Applications

1. Wafer Tray Position Verification

Ensures proper placement and alignment of semiconductor wafers in tight robotic transfer environments.

Problem Solved

Space constraints in wafer handling robots often preclude standard sensors; the ultracompact flat-form profile securely monitors proximity (5-30 mm) without physical contact, averting wafer damage.

2. Blister Pack Jam Detection

Monitors the tight conveyor transition zones in high-speed pharmaceutical packaging lines for jammed blister packs.

Problem Solved

Unnoticed jams damage machinery; the 1 ms high-speed response and Dark-ON trigger rapidly detect blockages against a background, while the IP67 housing resists periodic washdowns.

3. Micro-Assembly Robotic Gripper Sensing

Verifies the presence of miniature components in the jaws of micro-assembly robotic end-effectors.

Problem Solved

Payload and spatial restrictions on robot arms limit sensor sizes; the lightweight footprint (~20g) and flexible 2m flying lead cable integrate seamlessly into gripper mechanisms for reliable pick-up confirmation.
