The Omron E3S-GS3B4 2M is a rugged, high-speed grooved-type photoelectric sensor engineered for accurate part detection in compact industrial automation setups. It features a fixed 30 mm sensing slot that allows easy installation without alignment of separate emitter and receiver units. Designed for detecting opaque objects as small as 6 mm in diameter, this sensor is ideal for tasks such as edge detection, part counting, or object verification on conveyors or automated arms.
The E3S-GS3B4 2M uses a 940 nm infrared LED and operates on a 12 to 24 VDC supply with tolerance and 10% max. ripple. It supports a load power supply of up to 24 VDC and a load current of 80 mA max. The response time is rapidβjust 1 ms for operate/resetβensuring real-time performance in fast-moving production environments. The one-turn sensitivity adjuster simplifies setup, allowing fine-tuning to match specific material types or sizes.
With a low current consumption of 40 mA, the sensor supports energy-efficient operation and long-term reliability. Visual feedback is provided by LED indicators that help monitor operation and assist in troubleshooting. It maintains stability in brightly lit environments, withstanding ambient light up to 10,000 lx (sunlight) and 3,000 lx (incandescent).
The E3S-GS3B4 2M is enclosed in a tough zinc die-cast housing with polycarbonate covers, offering strong resistance to impact, vibration (10 to 55 Hz), and mechanical shock (500 m/sΒ²). It also meets IEC IP67 standards, ensuring protection from dust and water in washdown or harsh industrial environments. It operates within a temperature range of β25Β°C to 55Β°C and handles humidity from 35% to 85% without condensation.
With its slim body, high-speed response, and easy slot-based design, the Omron E3S-GS3B4 2M is a preferred choice for OEMs and automation engineers building space-sensitive, reliable detection systems across industries such as packaging, labeling, and electronics manufacturing.
