Miniature Photoelectric Sensor Infrared Sensor Optical Sensor for Counting

A: We offer a comprehensive range of composite (multi-parameter) sensors, including: Dust Sensor (PM1.0/PM2.5/PM10/TSP), Temperature & Speed Composite Sensor, Temperature & Pressure Composite Sensor, Temperature & Vibration Composite Sensor, Temperature/Humidity/Vibration 3-in-1 Sensor, and other customized composite sensor solutions. Each series integrates two or more measurement functions into a single housing, reducing installation complexity and system cost.

A: Factory-direct pricing with guaranteed quality we are a manufacturer, not a trading company. Our in-house R&D team ensures every sensor balances functional excellence (high accuracy, stable performance), aesthetic design (clean, professional industrial look), and practical usability (wide environmental adaptability, easy installation). We don't just make sensors that work we make sensors that look and feel like premium industrial instruments.

A: "Customer needs are our mission. We deliver the finest products to make friends worldwide." Every order is not just a transaction, but the beginning of a long-term partnership. Understanding your requirements, solving your problems, and exceeding your expectations-that is what drives us every day.

A: Yes. Our composite sensors carry CE, RoHS, ISO9001:2015 certifications. IP68 tested for Temperature-Pressure, Temperature-Vibration, and Temperature-Speed series.
