What Is industrial ethernet switch poe? In addition to network data transmission, a PoE Switch device is with a built- in Power over Ethernet injector to offer up to 100W Power over Ethernet ( PoE ). It ensures the power supply to devices such as IP cameras, VoIP phones, and wireless access points based on the standards of 802.3af, 802.3at and 802.3bt. H3B developed standard POE devices, rather than old generation POE. When other network devices are connected to our POE devices, the switch will detect whether they are POE-compatible or not. If yes, it will automatically supply power, otherwise, the power supply will stop to avoid the burning of ending equipment. By installing an H3B PoE Switch, it can help save lots of installation and maintenance costs by removing the need to install additional electrical wires and outlets. Besides, customers no need to worry about the burning from compulsive power supply as the old generation of POE products. What Can H3B outdoor poe switch Do for Us? H3B Industrial POE switches are compact DIN-Rail PoE Switches, which are designed for the application in POE needed industrial environments. H3B PoE Industrial Switch series are classified as Layer 2 Power Sourcing Equipment (PSE). The unique design with 100% brand new and pre-examined components, makes it a perfect choice for the use in the following scenes: Oil & Gas Urban Infrastructure Safe Campus Industrial & factory automation Marine & mining Rail & ITS What POE Options Can H3B Outdoor POE Switch Offer? After years of hard work, H3B developed a full range of PoE/PoE+ switches with up to 24-port fiber optic Gigabit PoE+ ports. In order to power high-power equipment over long distances, we also developed models with up to 60 W output per port. In addition, these PoE Switches are defined as Power Sourcing Equipment (PSE). While Ethernet data transmission, all H3B Industrial POE switches are able to provide up to 30 watts of power to the PD(Powered Devices) sides, such as IP phones, IP cameras and all kinds of wireless access points. With a compact industrial-grade design, our industrial PoE switche provide surge protection of 3 kV per LAN port. Furthermore, all H3B industrial POE switches are with compact IP30 housing designs to survive the dusty outdoor industrial sites.

PCB is the printed circuit board, which is one of the important parts of the electronics industry. Almost every kind of electronic equipment, from electronic watches, calculators, to computers, communication electronic equipment, military weapon systems, as long as there are electronic components such as integrated circuits, in order to make the electrical interconnection between each component to complete PCB board product. By PCB Structure Printed circuit board structure is also very complicated, including single layer, double layer and even multiple layers.They can be divided into single- layer boards, double-layer boards, multilayer boards and double-sided boards. By PCB Hardness Performance PCB board can be divided into rigid pcb, flexible pcb (FPC) and rigid-flex pcb according to the hardness. By PCB Hole In terms of function, the holes can be divided into two categories, one is used for electrical connection between each layers; The other is used to fix or position the components. By PCB Material Conventional PCB provide Immersion Gold PCB, Gold Fingers PCB, Immersion Silver PCB, Aluminum PCB, Lead Free HASL PCB, HASL PCB and OSP PCB.

Blank copper pcb board is a printed circuit board, also called printed wiring board, which is an important electronic component, the support of the electron component, and the supplier of the electrical connection for the electron component. Since it is made with electron printing, it is called a "printed" circuit board. As the electronic instruments become more and more complicated, the parts they need become much more accordingly, and the circuit and the parts on the board become denser. The blank PCB (without parts on) is often called the "Printed Wiring Board (PWB)". The substrate of the board is made of materials with attribution of insulation, thermal insulation, and inflexibility. The tiny wires can be seen on the surface is the copper foil which had been covered the whole board, but partially etched, then the remaining part formed the tiny netted wires. And these wires are called conductor pattern or electric wiring, which is used for offering the electrical connection for parts on PCB. Generally, the color of the PCB is green or brown, which is the color of the solder mask. It is the protective layer of insulation to protect the copper foil and preventing the parts from being soldered onto the incorrect positions. Silkscreen will be printed on the solder mask where words and marks (mostly white) will be printed in order to highlight each position of the parts. The silkscreen is also called a legend.

PTH Hole in PCB / PTH PCB There are three common types of drilled holes in the printed circuit board: PCB through hole plating , blind via hole, and buried via hole. Therefore, PCBs are classified according to drilling methods and can be divided into plated through-hole PCB, blind via hole PCB, and Buried via hole PCB. PTH is the most common drilling method, and it is common in various types of PCBs. SPEEDAPCB has been focusing on the production of various PTH (plated through hole PCB-PTH PCB), buried via hole PCB and blind via hole PCB. HAVE A QUESTION OR REQUEST? Click below, we’ll be happy to assist. Drilling Method of Plated Through Hole PCB Plated Through Hole, the copper foil lines between conductive patterns in different layers of the circuit board are connected or connected with this type of hole, but the copper legs of the component lead or other reinforced materials cannot be inserted. The PCB is formed by the accumulation of many copper foil layers. The copper foil layers cannot communicate with each other because each layer of copper foil is covered with an insulating layer, so they need to rely on via for signal connection. The through hole of the circuit board must pass through the plug hole to meet the customer's needs. In changing the traditional aluminum sheet plugging process, the solder mask and plug hole on the circuit board surface are completed with a white net to make its production more stable and the quality more reliable , More perfect to use. The vias help the circuits to be connected to each other. With the rapid development of the electronics industry, higher requirements are also placed on the PCB manufacturing process and surface mount technology. The plugging process for vias came into being, and at the same time, it must meet the following requirements: 1. Only copper is required in the hole, solder plug can be plugged or not; 2. There must be tin-lead in the hole, with a certain thickness requirement (4um), to avoid solder mask ink entering the hole, causing tin beads to be hidden in the hole; 3. The through hole must have a solder resist ink plug hole, opaque, no tin rings and beads, and must be flat. Through-hole boards are common in all fields and are one of the most common PCBs. Generally, the mobile phone board or PDA board has a board that uses a combination of blind and buried holes. The buried hole can reduce the probability of signal interference, maintain the continuity of the transmission line's characteristic impedance, and save routing space. Circuit board design. This type of board requires high technical content and accurate accuracy, so relatively speaking, the requirements for factory equipment are much higher than ordinary multilayer boards, and the cost of such circuit boards will be much higher than ordinary Shelf should be high.
