【English Product Introduction】
The SZGB-20 Photoelectric Tachometer Sensor is a non-contact rotational speed measuring device developed with advanced optical principles, specifically designed for industrial automation and equipment condition monitoring applications. Utilizing innovative photoelectric sensing technology, it captures reflected light variations from markers on rotating components to achieve real-time speed detection for various rotating bodies including shafts, gears, and impellers, compatible with both metallic and non-metallic materials.
Equipped with a high-sensitivity photoelectric conversion module, the sensor maintains stable signal acquisition within 50mm to 300mm detection range. Featuring 0.1Hz-20kHz broad frequency response, it accommodates speed measurement requirements from low-speed precision equipment to high-speed rotating machinery. The optimized signal processing circuitry effectively suppresses ambient light interference, ensuring reliable operation under challenging conditions (-25℃ to +85℃ temperature range, ≤95% relative humidity).
Constructed with 304 stainless steel housing and IP67 protection rating, the compact unit combines mechanical durability with exceptional dust/water resistance. Modular design facilitates easy installation and maintenance, featuring standard M18 threaded interface and adjustable mounting bracket for multi-angle positioning. The sensor provides NPN/PNP compatible square wave output for direct PLC integration, with optional 4-20mA analog output for diversified industrial control systems.
Widely applied in automotive manufacturing, textile machinery, printing/packaging, and water treatment industries, this device excels in motor speed monitoring, equipment safety protection, and production rhythm control. Its vibration-resistant structure ensures reliable measurement in stamping equipment and construction machinery environments. Dual-color LED indicators provide instant operational status feedback, significantly enhancing field debugging efficiency.
