Product Description

1. High-Precision Sensing Technology

 

The OMORN E3T-SL21 is a compact inductive proximity sensor engineered for accurate non-contact detection in industrial automation. With a 1.2mm sensing range and M5 threaded housing, it delivers precise positioning for small parts, robotic arms, and machinery components. Its fast response time (100μs) and 4kHz switching frequency enable high-speed operations in assembly lines and packaging systems. The sensor features a robust stainless steel body and IP67-rated design, resisting dust, water jets, and oils. Technical specifications include 10-30V DC power supply, NPN/PNP output options, and short-circuit protection. EMI/RFI shielding ensures interference-free performance in electromagnetic environments.

2. Rugged Design for Harsh Environments

 

Built for durability, the E3T-SL21 withstands extreme conditions with a temperature range of -25°C to +70°C. Its flush-mount M5 design allows seamless integration into tight spaces, while the gold-plated contacts prevent corrosion and ensure reliable conductivity. The sensor’s mechanical life exceeds 10 million cycles, outperforming standard sensors by 50%. OMORN’s ISO 9001 certification guarantees quality, and the 2-year warranty reflects confidence in its long-term performance. Ideal for automotive manufacturing, metalworking, and food processing industries, it meets CE, RoHS, and UL compliance standards.

3. Versatile Applications & Custom Solutions

 

Designed for flexibility, the E3T-SL21 excels in part counting, position monitoring, and collision avoidance systems. Its compatibility with PLCs and industrial control systems makes it suitable for AGVs, CNC machines, and conveyor belts. OMORN offers customizable options, including cable lengths (2m to 5m), connector types (M8/M12), and output modes (light/dark-on). Factory-direct pricing and technical support reduce integration costs and downtime. With 30% lower power consumption than competitors, this sensor balances efficiency and affordability, making it a top choice for OEMs and system integrators seeking reliable automation solutions.
