Use SMT switch and DFH02 plastic PCB fuse holder correctly

Use SMT switch and DFH02 plastic PCB fuse holder correctly
Correct use of switch mounting machine
With the development of science and technology and the progress of the times, we keep up with the trend of the times Of course, many companies and manufacturers have also achieved production automation In the SMT component industry, we have also made breakthroughs in automated production By using SMT machine S, we can achieve high quality, efficient and fast production This is a way for us to widely promote SMT, and there are many changes in the SMT machine. If you can correctly use the switch, it will enable us to get twice the result with half the effort. Now let us see how to use this SMT machine switch correctly
The smt switch can be divided into two parts, one is the emergency switch, and the other is the full stop switch. In use, we must distinguish between the two switches. The two switches have different functions. The emergency switch can be used so that we can deal with the failure of the emergency mounting machine. The master stop switch can stop all production tasks immediately. We must make different decisions according to your different needs
When we use the emergency switch, which is usually used in an emergency situation that endangers life or threatens to damage the machine, we will use the emergency switch. If the emergency switch is also used during normal operation, all machines will stop immediately. Servo power, the machine will stop immediately.

If the full stop switch is selected, the machine will stop after completing the step
If the machine absorbs water, stop the machine after repair. At this time, press the emergency switch, the placement machine will stop sucking immediately, which obviously cannot achieve our goal. This problem cannot be ignored when using SMT mounter.
New DFH02 plastic PCB fuse bracket for PCB and through-hole installation
Vertical direction; 22.6mm pitch, UL94V-2 polycarbonate cover,
On April 1, 2021, Wellingburg, UK: Hylec APL, a professional supplier of power components and enclosures, introduced a new 5mm x 20mm PCB fuse holder DFH02, which can be used for PCB or through hole installation. DFH02 has a transparent insulating cover, which can provide protection for fuses and facilitate installation and removal. The fuse holder is the most popular and best-selling fuse holder in the market.
Hylec's DFH02 PCB fuse holder is suitable for all types of circuits. It provides a safe and reliable method for installing fuses on all types of PCB, and eliminates problems caused by using fuse clips on PCB. DFH02 fuse holder is easier to install than the fuse clip, and the price is low, ensuring reliable electrical and mechanical connection.
DFH02 with 22.6mm spacing can be directly installed on the PCB horizontally or vertically through the through-hole. The maximum rated current is 6.3A at 250VAC.
The base material is thermoplastic material, filled with PA66 glass, with mechanical strength and excellent dimensional stability. Comply with UL94V-0 flame retardant standard. The grade of transparent insulating cover is UL94-V2.
The dimensions of DFH02 base are: 13. 5mm high, 9.0mm wide and 22.0mm long from the printed circuit board Leading distance is 22.6mm The total height excluding PCBA circuit board is 15.0mm
