How the Sensor and Manual Knob Work Together
The JH-WL021 gives you two ways to run water, so it’s worth understanding what each control does:
- Sensor (automatic flow): An infrared sensor detects your hands near the spout and starts the water flow. Move away, and it stops. This is the main, hands-free way to use the tap.
- Manual knob (on/off and flow): A high-density PP knob lets you turn the water on and adjust the flow rate manually when you’d rather have hands-on control, or as a backup.
In practice, the sensor handles everyday hands-free washing, while the knob provides a manual option to set the flow. Confirm your preferred control setup with our team when you order.

Key Features
1. Touchless Sensor Operation
An infrared sensor detects your hands, runs water automatically, and stops when you move away. This keeps our hands free and helps reduce touch contact with the tap during routine washing — a practical benefit at shared wash points.
2. Manual PP Knob for Hands-On Control
A high-density PP knob turns the water on and adjusts the flow when you prefer manual control or need a backup. Shaped for a comfortable grip, it stays easy to use with wet or gloved hands.
3. Thickened Copper Body with Matte Epoxy Coating
A durable, thickened copper core with a matte epoxy finish that helps the outer body resist routine splash exposure, UV, and heat in general lab conditions, keeping the surface clean over time.
4. Ceramic Valve Core
A precision ceramic valve core rated for a 500,000-cycle service life, for smooth, leak-free control and a long working life with less maintenance.
5. 360° Swivel Gooseneck Spout
Rotates fully to direct flow across the entire basin, making it easy to rinse glassware and fill containers, with sensor-activated flow that expands your washing reach.
6. Dual AC/DC Power Supply
Runs on AC or DC power, so it fits a wide range of lab setups — mains-wired or battery-backed. Confirm which power mode suits your bench when you order.
Applications
The JH-WL021 is built for hands-free, sink-side utility use where reduced touch contact helps:
- Shared wash stations — hands-free water points for common sinks used by many people throughout the day.
- Hand washing — Sensor-activated flow keeps hand washing quick and touch-free at busy benches.
- General rinsing and cleaning — Rinsing glassware and clearing routine residue without reaching for a handle.
- Teaching and testing labs — Automatic flow reduces wear from constant manual handling and helps limit unnecessary running.
Its primary role is hands-free washing and rinsing at the bench sink, keeping the wash point convenient at stations where several users share one tap. It supports cleaner, hygiene-conscious workflows by reducing hand contact — it’s a practical, hands-free tap, not a substitute for dedicated contamination control or medical-grade equipment.
Installation & Compatibility
The JH-WL021 mounts on a standard lab sink and requires a water supply and a power source for the sensor. For a clean, secure fit:
- Confirm that the mounting hole in your bench or sink matches the tap base and that there is room for the spout to swivel freely.
- Check the inlet connection — confirm the connection size matches your bench plumbing without adapters, and confirm whether you need a cold-only or hot-cold supply.
- Confirm your power supply — the sensor runs on AC or DC, so check which is available at the bench and how it will be wired.
- Confirm your water pressure sits within a stable working range for consistent sensor-activated flow.
- Keep the sensor window clear — allow easy access to wipe the sensor area so it responds accurately.

FAQ
How do the sensor and manual knob work together?
The infrared sensor is the main hands-free control — it starts the water when your hands approach and stops it when they move away. The high-density PP knob is for manual use: it turns the water on and adjusts the flow rate when you prefer hands-on control or want a backup. Tell us your preferred setup, and we’ll confirm the control configuration for your order.
Is the JH-WL021 cold-only or hot-cold?
This model runs from a single water supply. Confirm whether you need a cold-only or hot-cold setup for your project, and we’ll advise on the right configuration. If you specifically need a hot-and-cold sensor tap, ask us about the sensor hot-and-cold version (JH-WL021A), and we’ll help you compare options.
What power supply does the sensor tap need?
The JH-WL021 works with AC or DC power, so it fits a range of lab setups — mains-wired or battery-backed. Check which power source is available at the bench and how it will be wired. If you’re unsure, tell us your setup, and we’ll confirm the right power option before you order.
How is it different from a manual lab faucet?
A manual faucet only runs when you turn the handle, so you touch it every time. The JH-WL021 runs water automatically via the sensor, keeping users hands-free and reducing touch contact at shared wash points. The manual knob is still there for hands-on control and flow adjustment when you want it.
Does the touchless operation make this a contamination-control faucet?
It helps reduce hand contact with the tap, which supports cleaner, hygiene-conscious workflows at shared sinks. It’s a practical hands-free washing point — not a substitute for dedicated contamination-control or medical-grade systems. If you have specific hygiene or compliance requirements, send us the details, and we’ll advise on suitability.
What is the body made of?
The body is thickened copper with a matte epoxy coating. The coating helps the exterior resist routine splash exposure, UV, and heat in general lab conditions. For specific or aggressive chemical exposure, send us the details, and we’ll confirm suitability.
How do I keep the sensor working accurately?
Wipe the body with a mild detergent and a soft cloth, then rinse. Keep the sensor window clear of splashes and buildup so it responds reliably, and avoid abrasive cleaners that could scratch the matte finish. The copper build and epoxy coating resist routine staining, so upkeep stays simple.
What should I confirm before ordering?
Confirm five things: your water type (cold-only or hot-cold), your inlet connection size, your available power supply (AC or DC), your mounting hole size, and your water pressure. Checking these in advance helps ensure a secure, reliable fit. Share your setup, and we’ll confirm compatibility.
How do I request a quote?
Send us your required quantities, water type, power setup, and inlet connection details. For a larger fit-out, share your bench and sink layout so we can confirm scope and lead time.
