Cutting & Engraving Laser Head 450nm, 2W for CNC and 3D printing machines

Description

PLH3D-2W Engraving Laser Head
Product description
Smallest but still powerful laser head from PLH3D series. PLH3D-2W is a medium power laser head equipped with 450nm laser diode and high resolution lens. Compact design and very light weight (70 grams) allow to install the laser head even in small and delicate machines. Driver equipped with LED informs the user when the laser head is armed.

More info
This is a PLH3D medium power 2W professional engraving laser head.
The laser head allows to cut or engrave materials such as wood, paper, leather, cardboard and many others.
This light weight 70 gram laser head doesn’t require any additional cooling. Fan design makes it work as a fully customized air nozzle protecting lens from dirt and cooling the laser head. PLH3D-2W works with common 12V power supply (min 1,5A current).
Driver is equipped with LED indicator, which displays all required information. The temperature control system, would turn off the laser head in case of exceeding critical temperature. Small sized driver attached directly to the laser head improves the speed of diode modulation. This also allows to connect longer cables to the head.
Analog modulation enables user to control the laser power. 0V = laser OFF, 5V laser ON, 2V ~40% power. This can also work as TTL using voltage from 0 to 5V.
In order to modulate the power through PWM, the base frequency has to be set between 5 and 10 kHz. Conducted thermal tests on several prototypes allowed us to optimize the radiator’s shape and enable efficient cooling, keeping up with a small size of the device. Besides the standard functionality, small sized laser spot gives the possibility to illuminate plates, covered with photosensitive surface, which gives a chance for very quick PCB prototyping.
For bulk orders PLH3D can be customized to all customers’ needs. Supply voltage may be switched to 24V. We can add customers’ logos and all possible additional features.
Main advantages of the PLH3D  2W:
- Customization offer for all 3D printers and CNC machines producers
- No need for additional cooling
- Simple installation to all 3D printers and CNC routers
- Driver attached to the head

Caution:
Remember that it is not a toy.
Laser radiation is dangerous even when scattered or reflected from any surface.
Always use proper protection laser filter on your CNC machine dedicated to 430 - 480nm in order to avoid reflected radiation.
Never point laser head at people or animals.
Do not touch the beam, it may cause burns or other injury.
Do not stare at the beam or the beam spot while the material is being cut.
Laser radiation - Avoid eye or skin exposure to direct or scattered radiation.
Class 4 laser product.
Protection
This module has thermal protection system which protect laser diode from overheating.
The analog input is protected by a 5V1 Zener diode on occasion there appears the voltage higher than 5V. Despite everything, this input should not be used with higher voltages.
The output of the driver is protected by Shottky diode which doesn't allow the reverse voltage to appear.
