Overview
The sensor faucet with extended spout is a hygienic and efficient solution for public and commercial washrooms. Its hands-free operation reduces cross-contamination risks, while the elongated spout accommodates deeper sinks or larger washbasins. Designed for durability, high-quality models use brass or stainless steel construction to withstand frequent use. The infrared sensor ensures consistent performance, with adjustable sensitivity to accommodate different user heights or sink configurations.
Structure and Working Principle
This faucet comprises three core components: the infrared sensor module, solenoid valve, and spout assembly. The sensor emits an invisible beam; when interrupted (e.g., by hands), it signals the valve to open for a preset duration (typically 5–30 seconds). The extended spout, usually 10–14 inches long, is engineered with laminar flow technology to minimize splashing. Some models integrate flow restrictors (1.0–1.5 GPM) to comply with water conservation standards without compromising user experience.
Key Features
Modern versions offer dual power options—battery (4–6 AA cells, lasting 2–5 years) or low-voltage AC adapters—with battery indicators for maintenance planning. Anti-limescale aerators maintain consistent flow in hard water areas. Advanced models include temperature control (mixing valve models), vandal-resistant designs, and programmable activation ranges (5–24 inches). The extended spout often features a 15°–30° downward angle to optimize water delivery.
Application Areas
Ideal for healthcare facilities due to infection control benefits, these faucets are also standard in airports (ICAO guidelines recommend touchless fixtures) and educational institutions. In food processing plants, the extended spout accommodates industrial hand-washing stations. High-end variants with brushed nickel finishes are specified for luxury hotels and corporate offices seeking both functionality and aesthetic appeal.
Maintenance and Precautions
Monthly cleaning with mild detergent prevents soap buildup on sensors. Hard water areas require quarterly aerator inspections; vinegar soaks dissolve mineral deposits. Avoid abrasive cleaners that damage finishes. For cold climates, specify freeze-resistant models with drain-down valves. Always verify compatibility with existing plumbing—most units require 0.1–0.5 MPa water pressure.
B2B Procurement Guide
Bulk buyers should request WRAS or NSF/ANSI 61 certifications for regulatory compliance. MOQs typically start at 50 units, with 5–10% price breaks at 200+ units. Leading manufacturers (e.g., TOTO, American Standard) offer OEM services for custom spout lengths (up to 18 inches) or logos. Consider bundled maintenance contracts—professional installation adds $25–$50 per unit but ensures optimal sensor calibration.
