【Hugong E3F-DS30C4 Photoelectric Proximity Switch Product Introduction (English Version)】
The Hugong E3F-DS30C4 photoelectric proximity switch is an industrial-grade detection device developed with advanced optoelectronic sensing technology, designed for non-contact object positioning and motion state monitoring in various automation scenarios. Featuring a compact integrated structure, its engineering-grade ABS composite housing combines lightweight construction with durable performance, ensuring reliable operation in demanding industrial environments.
Utilizing infrared beam transmission and reception principles, this device integrates high-sensitivity optical components to detect object presence by analyzing light beam interruption or reflection. With a sensing distance of 30cm, it demonstrates strong resistance to ambient light interference while maintaining stable detection capabilities in environments with moderate dust or oil mist contamination. The switch offers both normally open (NO) and normally closed (NC) output configurations, ensuring compatibility with mainstream industrial control systems including PLCs and frequency converters.
Available in NPN and PNP transistor output variants, this model accommodates diverse electrical system requirements. Its optimized circuitry incorporates reverse polarity protection, overload prevention, and short-circuit safeguards to enhance operational reliability. The fully enclosed structure provides effective protection against particulate intrusion and liquid splashes, operating reliably within a temperature range of -25℃ to +55℃. Flexible mounting options including threaded fixation and bracket installation enable multi-angle adjustment, facilitating rapid integration with conveyor systems, robotic arms, packaging machinery, and other industrial equipment.
Typical applications encompass material presence detection in automated production lines, pallet positioning in logistics systems, sheet counting for printing presses, and elevator door safety monitoring. Routine maintenance should include periodic cleaning of the optical window to preserve detection accuracy, with avoidance of direct exposure to highly corrosive substances.
