Spec Sheet - SK-EW

Availability	In Stock
Condition	Brand New

Achieve the ultimate minimalist aesthetic with the SkyDance SK-EW, a concealed LED touch sensor switch designed for seamless integration into furniture and architectural surfaces. This innovative sensor allows you to add sophisticated lighting control without any visible switches. By mounting it behind non-metallic panels such as wood, glass, or plastic, you can create a touch-sensitive zone for on/off and dimming functions. It's the perfect solution for high-end custom cabinetry, smart desks, retail displays, and any project demanding a clean, modern finish. Operating on a safe 5VDC, it outputs a standard PWM signal, making it a versatile component for controlling various low-voltage LED lighting systems.

Key Features

Through-Surface Sensing

Installs behind wood, glass, or plastic panels, creating an invisible, touch-sensitive control point.

Intuitive Dual-Function Control

A short touch toggles the light on or off, while a long touch smoothly dims the brightness up or down.

Flicker-Free PWM Dimming

Features a 2KHz PWM frequency output for a smooth, continuous 0-100% dimming range without visible flicker.

Safe Low-Voltage Operation

Versatile Signal Output

Outputs a standard 5V level or PWM signal, compatible with a variety of LED drivers and controllers.

Compact & Discreet Design

Its small footprint (33.5 x 19mm) allows for easy installation in tight spaces within furniture and fixtures.

Technical Highlights

Advanced capacitive sensing technology for reliable detection through non-conductive materials up to 5cm thick.
High-frequency 2KHz PWM output ensures smooth, comfortable dimming compatible with sensitive cameras.
Integrated logic for both momentary (on/off) and sustained (dimming) touch detection.

Application Scenarios

Custom Cabinetry & Kitchens Integrate this dimmer touch sensor switch into cabinet doors, side panels, or under countertops for invisible control of under-cabinet or in-cabinet lighting. A simple touch on the wood surface activates the lights.

Smart Furniture & Shelving Build touch-sensitive controls directly into desks, headboards, bookshelves, and entertainment centers. Provide a premium, seamless user experience without cluttering surfaces with physical switches.

Retail & Museum Displays Create clean, interactive display cases where customers can illuminate products by touching the glass or acrylic. This minimalist approach focuses all attention on the merchandise, not the hardware.

Architectural & Interior Design Embed sensors behind decorative wall panels, mirrors, or backsplashes to control accent lighting. This allows for creative lighting control that becomes part of the room's design itself.

How to Control & Use This Sensor Switch

Step 1: Mounting - Securely affix the sensor module to the back side of your chosen non-metallic surface (e.g., wood, glass, plastic). Ensure the central sensing area is aligned with where you intend to touch.
Step 2: Power Input - Connect the input wires to a regulated 5VDC power supply. The Red wire connects to Positive (+) and the Black wire connects to Negative (-).
Step 3: Signal Output - Connect the output wires to the signal input of your LED controller or driver. The Yellow wire is the PWM signal output, and the Black wire is the common ground (-).
Step 4: Operation - Once wired, touch the front surface of the panel. A brief tap will turn the lights on or off. A sustained press-and-hold will cycle the brightness up and down.

⚠ Precautions

Ensure the material thickness does not exceed the 5cm maximum detection range for reliable operation.
This sensor is designed for low voltage systems. Only use a compatible 5VDC power supply.
The sensor will not function if mounted on or behind metallic or conductive surfaces.
This device outputs a control signal; it does not directly power LED strips. It must be used with a compatible LED controller or driver.

Frequently Asked Questions

Q: What materials can this touch sensor work through?

A:It is designed to work through non-metallic materials like wood, glass, plastic, acrylic, and stone up to 5cm thick.

Q: Will this sensor work if I mount it behind a metal panel?

A:No, capacitive touch technology does not work through metal or other conductive surfaces.

Q: What kind of power supply is required for the SK-EW sensor?

A:This sensor requires a stable, regulated 5VDC power supply for proper operation.

Q: How do I dim the lights with this sensor?

A:To dim, simply press and hold your finger on the surface above the sensor. It will cycle through brightness levels until you release your finger.

Q: Can this sensor power my LED strip directly?

A:No, this is a sensor that outputs a low-power 5V PWM signal. It must be connected to an LED controller or a driver that accepts a PWM input to control your lights.

Q: Is the touch sensitivity adjustable?

A:The sensitivity is factory-set for a detection range up to 5cm and is not user-adjustable.
