Engraving laser head 445nm 5W + thermal protection + holder + PSU. Output optical power at 20C. 7,5 - 12 V. YES - 7,5V 5A.
Its aluminium body ensures proper heat transfer to other metal parts which cool the laser head. Thanks to its shape it can be mounted to flat surfaces or be placed in 43mm diameter spinde holders.PLHD-5000 driver ensures proper work of the laser head and protect laser diode from overheating. When the laser head reaches 40 degrees Celsius the orange red is starting to glow. Reaching 45 degrees makes the red diode to glow and driver is switching off the laser diode for as long as the temperature is not lower than 40 degrees. It also sends low signal on the 5th ping on the output wires while in overheat mode. Advantages of the PLH-5000 over the CLH-5000: -Thermal protection shutdown over 45C.
LED indicators (temperature and warning). Output signal in overheat mode. HQ window protecting collimator from dust and smoke. Different mount type: in spindle holder or to the surface. Better heat transfer to laser head body.Turning collimating lens allows to change the beam focus distance. Additional window is protecting the lens from dust and smoke. Window is much easier to clean thanks to bigger size and flat surface. Air flow is needed to keep lens and window clean during operation. In order to turn lens and change focus distance front window cover should be removed (three M3 screws). The laser head allows to cut or engrave materials such as wood, paper, leather, cardstock and many other. Thanks to full analog modulation it is possible to engrave in shades of grey or change the output power during turns. High speed modulation (up to 100 kHz) allows to use high movement speed during engraving even complicated patterns. Module is using brand new NUBM44 450nm diode (capable of 6W). On this listing PSU 7,5V 5A is included. Depending on the availability of the PSU from our suppliers, PSU included to the engraving laser head can look a bit different.
Anyway all connector pins are always matching PSU send to customer. If you would like to know any details of the PSU please write to us.
Aluminium holder or four mounting holes on the head allow to mount the engraving laser head on the moving part of the machine. Single 6 mm diameter hole in holder is designed for compressed-air system tube (tube is not included).
Holder can be mounted to the machine with M6 screws (included). Laser head can be mounted directly using four M4 screws which are also included. For each module two kind of collimating lens are attached.One is a single lens with AR coating which allows to get more power and shorter focal distance. Second one is three element lens with AR coating which allows to use bigger power density and larger focus distance. While turning the lens please be careful not to put dust or dirt on the lens or in the chamber after lens. Modulation inputs can be used as TTL inputs with its logic levels of 0V and 5V or as an analog input. Analog modulation means that by using 2,5 V on ANG input you get 50% output power, analogically by using 4 V you get 80% output power, etc. Red Plexyglass 3mm: 100 mm/min 4 passes (no smoke). Plywood 10mm: 300mm/min 5W 10 passes (1 pass for each mm). Vinyl 2mm: 100mm/mi 5W 1 pass (the smoke must be removed quickly). Other speeds and materials: Wood 3mm: 200mm/mim 5W 3 passes (1 pass for each mm) InchJet Photographic paper: 400mm/min 5W 1 pass Paper: 600mm/min 2W. 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.Do not stare at the beam or the beam spot while the material is being cut. Air flow is very important during the engraving process since it is blowing out dark smoke which can cause optical obstacle for a laser beam. 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.
