OMRON E4A-3K Capteur à ultrasons réfléchissant * LIVRAISON LE JOUR MÊME - 1 UNITÉ SEULEMENT*

Description

Designed for reliable non-contact distance measurement, the Omron E4A-3K operates as a high-performance ultrasonic reflective sensor. This unit utilizes acoustic wave technology to detect objects within a user-selectable range, eliminating the common detection challenges associated with target color, transparency, or surface reflectivity. It serves as a dependable solution for industrial automation setups where physical contact with the target is not feasible or desired.

The sensor features a dual-range selection mechanism that allows engineers to configure the detection zone between 0.3 and 3 meters. Operating at an ultrasonic oscillation frequency of approximately 40 kHz, the E4A-3K projects a controlled acoustic cone, ensuring highly precise detection of both metallic and non-metallic objects. Housed in a robust industrial enclosure, this sensor is designed for stationary integration in processing, packaging, and material handling systems.

Features

• Adjustable dual-range sensing zones (0.3 to 2 meters or 1.3 to 3 meters) for application flexibility.
• Non-contact acoustic detection independent of target color, transparency, or material type.
• High-frequency 40 kHz ultrasonic oscillator for reliable signal propagation and echo return.
• Robust mechanical construction capable of resisting significant operational shocks up to 50G.
• Clear target resolution suited for pipes, flat plates, and large industrial components.

Applications

• Diameter, loop, and tension control in paper, plastic, and metal web processing lines.
• Level and presence monitoring in bulk storage, material hoppers, and packaging lines.
• Position sensing and collision prevention for automated guided vehicles (AGVs) and overhead cranes.
• Object detection and sorting on heavy-duty conveyor systems.

Installation Guidelines

• Mounting Alignment: Mount the sensor securely to a rigid structure to eliminate vibration. Align the active sensor face perpendicular to the target surface to maximize the echo signal return.
• Environmental Precautions: With an IEC IP60 rating, ensure the sensor is installed in dry, indoor environments protected from direct water exposure, extreme humidity, and high concentrations of conductive dust.
• Wiring: Route control and signal cabling away from high-voltage AC lines or motor drives to minimize electromagnetic interference (EMI). Use shielded cable for signal lines.
