Product Description

About the PLH3D-2W Engraving Laser Head

PLH3D-2W is the medium power 2W professional engraving laser head. This laser head allows to cut or engrave materials such as wood, paper, leather, cardboard, and many others.

This lightweight 70-gram laser head doesn’t require any additional cooling. Fan design makes it work as a fully customized air nozzle protecting the lens from dirt and cooling the laser head. PLH3D-2W works with common 12 V power supply (min 1.5 A current).

The driver is equipped with an LED indicator, which displays all the required information. The temperature control system would turn off the laser head in case of exceeding critical temperature. The small-sized driver attached directly to the laser head improves the speed of diode modulation. This also allows connecting longer cables to the head.

Analog modulation enables the user to control the laser power. 0 V = laser OFF, 5 V laser ON, 2 V ~40% power. This can also work as TTL using a voltage from 0 to 5 V.

In order to modulate 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 a photosensitive surface, which gives a chance for very quick PCB prototyping.

About the PLH3D-CNC Universal Laser Adapter

The key function of the PLH3D-CNC Adapter is to “arm” and “disarm” the laser head. Arming means turning the head power supply on; the armed head is then able to generate laser beam. Disarming (turning the head power supply off) brings the laser head in a safe state where generating laser beam is fully impossible.

The laser head may be checked by generating a short laser pulse at maximum power.

Built-in safety means prevent misuse and unexpected behavior at emergency. The key switch protects the laser head against arming by children and other unauthorized persons. Arming the laser head is always done manually by the user, by pressing a button. A special circuitry prevents arming at any malfunction of internal electronics. The laser head is being automatically disarmed in case of emergency: loss of the mains supply, PSU failure, breaking or disconnecting the laser head cable. After disarming, the system remains in a safe state and rearming always requires pressing the button by the user.

Key features of the PLH3D-CNC Adapter:

  • Soft Start
  • Indication LEDs - power, armed, laser working
  • Build-in microcontroller - watchdog
  • Two programmable enable inputs
  • Two external safety terminals (for example: safety key, E-Stop)
  • Automatic disarm after power off
  • One second laser test
  • Compatibility with the PLH3D laser heads
  • Keylock for preventing use by unauthorized personnel
  • Machined aluminum quality enclosure
  • One button system (arm, test and setting of enable modes)

7 types of wires - universal connectors

Description of connectivity wires for different physical connectors available in your CNC machines. Simply choose the one which fits your machine!

Universal Kit Pins

1. Male gold pin header connector -  allows connecting to a gold pin female connector. One needs to find two slots responsible for modulation signal. Analog output 0-5 V or Analog output 0-10 V or TTL/PWM output, and GND. Simply plug the blue wire to the GND and red wire to the signal which is used by the machine to operate the laser. Use the terminal block electric strip to connect the blue and red wire with labeled wires of the Universal Adapter.  

2. Tinned copper wires -  allows connecting to SMD or THT of the CNC controller. One needs to find two vias/holes or parts on the PCB responsible for modulation signal. Analog output 0-5 V or Analog output 0-10 V or TTL/PWM output, and GND. Simply solder the wires to the part of the PCB board of the controller, the blue wire to the GND signal and red wire to the signal which is used by the machine to operate the laser. Use the terminal block electric strip to connect the blue and red wire with labeled wires of the Universal Adapter.

3. Female gold pin header connector -  allows connecting to a gold pin male connector. One needs to find two pins responsible for modulation signal. Analog output 0-5 V or Analog output 0-10 V or TTL/PWM output, and GND. Simply plug the blue wire to the GND and red wire to the signal which is used by the machine to operate the laser. Use the terminal block electric strip to connect the blue and red wire with labeled wires of the Universal Adapter.  

4. Insulated wire end sleeves - allows connecting to terminal blocks and screw connectors. One needs to find two terminals of a connector responsible for modulation signal. Analog output 0-5 V or Analog output 0-10 V or TTL/PWM output, and GND. Simply insert the blue wire to the GND terminal and red wire to the modulation signal terminal which is used by the machine to operate the laser and tighten the screws. Use the terminal block electric strip to connect the blue and red wire with labeled wires of the Universal Adapter.

5. Male D-SUB connector -  allows connecting to any kind of a female D-SUB connector. One needs to find two slots responsible for modulation signal. Analog output 0-5V or Analog output 0-10 V or TTL/PWM output, and GND. Simply plug the blue wire to the GND and red wire to the signal which is used by the machine to operate the laser. Use the terminal block electric strip to connect the blue and red wire with labeled wires of the Universal Adapter. 

6. Press fit male gold pin header connector -  allows connecting to a gold pin male connector. One needs to find two vias/holes in the PCB responsible for modulation signal. Analog output 0-5 V or Analog output 0-10 V or TTL/PWM output, and GND. Simply press the connector into the via/hole in the PCB board of the controller, the blue wire to the GND and red wire to the signal which is used by the machine to operate the laser. Use the terminal block electric strip to connect the blue and red wire with labeled wires of the Universal Adapter.    

7. Female D-SUB connector - allows connecting to any kind of a male D-SUB connector it can also be used to connect to other types of connectors which are using male pins. One needs to find two pins responsible for modulation signal. Analog output 0-5 V or Analog output 0-10 V or TTL/PWM output, and GND. Simply plug the blue wire to the GND and red wire to the signal which is used by the machine to operate the laser. Use the terminal block electric strip to connect the blue and red wire with labeled wires of the Universal Adapter.

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 - 480 nm in order to avoid reflected radiation.
  • Never point laser head at people or animals.
  • Do not touch the beam, it may cause burns or another 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.
