NEJE S1 IR 4W: 3.5kW Peak Power DPSS Module for CNC & Laser Engravers, Universal Fit
NEJE S1 IR 4W Laser Module – The Professional Solution for Metal Deep Engraving
The NEJE S1 utilizes an advanced 1064nm End-Pumped DPSS laser source, delivering 3.5W+ average power and a massive 3.5kW instantaneous peak power. Unlike conventional fiber-coupled engravers, the end-pumped design generates significantly higher single-pulse energy, making it the definitive solution for deep engraving on reflective metals. It effortlessly performs deep engraving up to 0.5mm on stainless steel, raw aluminum, and critical plated surfaces, creating tactile, permanent marks that stand up to wear and environmental exposure. It also supports versatile processing techniques, including black marking on copper, iron, anodized aluminum, nickel-plated surfaces, and painted metals.
Featuring PWM multi-level power control, the S1 allows precise adjustment for both fine marking and deep engraving, while the red-light assist ensures rapid and accurate focusing. The integrated intelligent PWM dynamic fan control automatically switches to a silent, half-speed mode when the PWM signal drops below 5%, ensuring ultra-low noise operation. Compact, rugged, and maintenance-free, the S1 brings professional-grade metal processing capabilities directly into your creative workflow.
Highlights
1. 3.5kW Peak Power for True Metal Deep Engraving
Utilizing a 1064nm End-Pumped DPSS source, the S1 delivers a massive 3.5kW instantaneous peak power. Unlike standard diodes, it achieves deep engraving up to 0.5mm on stainless steel and raw aluminum, creating tactile, permanent marks that resist wear and corrosion.
2. Versatile Material Mastery: Metals, Plastics & Acrylics
Beyond high-contrast black marking on copper, iron, and anodized surfaces, this module excels at fine engraving and cutting on plastics and acrylics (PMMA). It is a true all-in-one solution for both industrial metal marking and non-metal fabrication.
3. Precision Control & Smart Focusing
Features PWM multi-level power control for the perfect balance between fine marking and deep engraving. The integrated red-light assist ensures rapid and accurate focusing, significantly improving workflow efficiency and accuracy.
4. Intelligent Cooling & Ultra-Low Noise
The integrated intelligent PWM dynamic fan automatically switches to a silent, half-speed mode when the PWM signal drops below 5%. This ensures optimal cooling performance while maintaining an ultra-quiet operation for indoor and long-duration tasks.
5. Universal Compatibility & Plug-and-Play
Designed for seamless integration, the S1 fits NEJE machines, major brand laser engravers, and CNC routers. Supporting standard industrial interfaces, it allows you to instantly upgrade your existing equipment with professional-grade IR capabilities.

Q&A
Q1: Is the NEJE S1 IR module compatible with older NEJE machines like the NEJE 5 or NEJE 3 Max?
A: The S1 IR module is designed with a universal mounting interface. With the optional adapter plate + dovetail holder, it mounts directly to the Max 4 module holder and remains backward-compatible with older NEJE frames (NEJE 3 Max, NEJE 5 series) via standard 4-pin/PWM interfaces. No firmware lock-in.

No firmware lock-in.
Q2: How easy is it to swap between the E80 (diode) and S1 (IR) modules?
A: Extremely easy. The community-proven dovetail + adapter plate method allows tool-free swapping in seconds. Users can alternate between the E80 24W blue diode (for wood/MDF/deep steel engraving) and the S1 1064nm IR (for stainless/aluminum/plated metal deep engraving) without mechanical rebuilds.
Q3: What materials can the S1 IR module actually process?
A: The S1 excels at deep engraving on 0.5mm stainless steel, aluminum, copper, and electroplated surfaces (chrome/nickel/zinc). It is purpose-built for reflective metals where blue diodes struggle. Not for cutting thick plate—focus is permanent, tactile marking and deep engraving.
Q4: Can NEJE offer a fully enclosed system with fume extraction for metal work?
A: This is acknowledged as a valuable direction. While the S1 module itself is open-frame compatible, NEJE recognizes demand for enclosed Class-4 stations with HEPA/activated-carbon filtration for metal/plastic fume safety. Community ideas (slot + tray) are noted for future accessory development.
Q5: What is the expected price point for the S1 IR module?
A: Early-bird pre-order pricing is positioned competitively against entry-level 4W IR lasers. Pre-order saves $70 (≈€65), ships within 24 hours. Final MSRP aligns with professional IR tools, not toy-grade pointers.
Q6: Does the S1 support grayscale or only depth/contrast marking?
A: Correct. The S1 uses PWM multi-level power control for switching between fine marking and deep engraving. It does not produce grayscale photos like a 300dPI blue diode (E80). Its strength is high-contrast, tactile, permanent metal marks.
Q7: Can the S1 be used for large-format work (e.g., 700×2000mm leather + guitar bodies)?
A: Yes. The S1 is a module, not a machine. Paired with extended-axis NEJE frames (Max 4 + extensions) it covers large-format metal plates, neck plates, amp panels, and custom knife etching. IR wavelength ensures consistent focus behavior across long travels when paired with proper mechanical calibration.
