RIKO RN04-N Proximity Switch Product Introduction (English)
The RIKO RN04-N series is a three-wire proximity sensor with NPN transistor output, designed for industrial automation applications. Operating at 24V DC power supply with normally open (NO) contact configuration, this square-shaped sensor (18×18×35mm) provides reliable non-contact detection for metallic objects. Its compact structure enables flexible installation in space-constrained environments.
Constructed with high-grade engineering plastic housing, the device features enhanced resistance to mechanical shock and chemical corrosion. Built-in protection circuits safeguard against voltage fluctuations and reverse polarity connection, ensuring long-term operational stability. The integrated dual-color LED indicator provides clear visual feedback for power status and detection activation, facilitating on-site commissioning and maintenance.
With millimeter-level detection accuracy, this sensor reliably identifies various metallic materials including iron, aluminum, and copper. The optimized electromagnetic field design ensures stable performance in environments with electrical interference or particulate contamination. The operational temperature range of -25℃ to +70℃ accommodates most industrial requirements.
Suitable for position detection, equipment safety protection, and conveyor counting systems, the universal design features IP67 protection rating for reliable performance in humid or oily conditions. The vibration-resistant terminal block maintains secure electrical connections, while standardized mounting dimensions ensure compatibility with various industrial brackets. This sensor provides cost-effective solution for automated production line applications requiring durable non-contact detection.
