DB-9 Male Right Angle Connector Designed to work with the EIA/TIA 232 serial interface standard, which determined the function of all nine pins as a standard, so that multiple companies could design them into their products. DB9 connectors are commonly used for serial peripheral devices like keyboards, mice, joysticks, etc. Also, they are used on DB9 cable assemblies for data connectivity. DB9 is used in many legacy devices that use the DB9 interface for serial communication. The connector module is a male right-angled connector with solder cups. Best suitable for mounting on circuit board. Connecting cables in tight spaces can be a problem in many applications. These low profile right angle D-Sub adapters solve this problem by allowing cables to be connected at a 90-degree angle. Three versions are available for each connector size allowing for cables to exit in opposite directions. Adapters are male to female, fully shielded and are over-molded with gray PVC. Mating hardware is reversible allowing for use in virtually any application. Applications: D-Sub confined space Enclosure applications OEM applications Serial data transmission Data networks Instrument control Device management

DB9 Female Straight Connector The most popular kind of electrical connector is DB9 Female straight Connector. The D-sub minuscule (D-sub) connector plug and socket family includes the DB 9 connector, which is used with computers and other communication equipment. A five-pin row sits above a four-pin row in the arrangement of DB-9 pins, which are organized in rows of two. The EIA/TIA 232 serial interface standard established the purpose of each of the nine pins as a standard so that different manufacturers may incorporate them into their products. DB9 connections are made to work with this standard. Keyboards, mouse, joysticks, and other serial peripheral devices were frequently connected using these connectors . For data communication, they are also utilized in DB9 cable assemblies. Today, more advanced interfaces like USB, PS/2, Firewire, and others have mostly taken the place of the DB9. However, the DB9 interface is still widely used by many vintage devices for serial communication. Applications: Network ports. Computer video output. Game controller ports. Linear and rotary encoders in industries.

DC 12V KK-P25/20 8KG Lifting Solenoid Electromagnet This DC 12V KK-P25/20 8KG Lifting Solenoid Electromagnet consists of an iron core and a coil to attract magnetic substances, using the magnetic action induced by electric current, only while the current is applied. This compact functional device offers high power with high reliability. The structure and design to release the residual magnetism left after de-energization is also one of its unique features. Working Principle: An electromagnet is simply a coil of wire. It is usually wound around an iron core. However, it could be wound around an air core, in which case it is called a solenoid. When connected to a DC voltage or current source, the electromagnet becomes energized, creating a magnetic field just like a permanent magnet. The magnetic flux density is proportional to the magnitude of the current flowing in the wire of the electromagnet. The polarity of the electromagnet is determined by the direction of the current. The north pole of the electromagnet is determined by using your right hand. Wrap your fingers around the coil in the same direction as the current is flowing (conventional current flows from + to -). The direction your thumb is pointing in the direction of the magnetic field so north would come out of the electromagnet in the direction of your thumb. DC electromagnets are principally used to pick up or hold objects. Precaution: Electromagnets must meet the following conditions to achieve maximum suction: The object to be sucked must have good magnetic permeability. Proper use of power supply, rated voltage. The object to be sucked must be flat and clean. The object to be sucked must be greater than or equal to the surface of the magnet( For example the magnet is 20 x 15 mm, so the surface area is S=r²?=10²? mm² so the object to be sucked must be greater than or equal to 10²? mm² ) The object to be sucked must be greater than 5mm. (If the thickness decreases, the suction decreases) The object to be sucked must be close, the middle can’t be interspersed with objects or gaps Suction means more than 5cm in thickness, and surface roughness, the surface is greater than the cross-sectional area of the electromagnet and maximum suction completely fits together on an iron-based material. Electromagnet in working conditions electromagnetic conversion would produce a certain amount of heat, electricity more frequently the higher temperature, which is a normal phenomenon.

It can be applied to many fields as there is a wide range of application. What is Relay ? Explained in simple terms. Operation Mode: P1: Trigger signal, the relay is on “OP” time, and then disconnect; Within the “OP” time, proceed as follows: P1.1: the signal is triggered again, invalid P1.2: the signal is triggered again, re-clocking P1.3: Signal has triggered again, the relay is disconnected, stop the clock; P-2: Trigger signal, after the “CL” time is off, the “OP” time is on. When the timing is completed, the replay will be disconnected; P3.1: Trigger signal, after the “OP” time is on, the “CL” time is off, then cycle the above actions. If trigger signal within the loop, the relay will be disconnected and stop the clock. The number of cycles ( “LOP “) can be set. P3.2: No need to trigger the signal after powering up, the “OP” time is on, the “CL” time is off, then cycle the above actions; The number of cycles ( “LOP “) can be set. P-4: Signal holding function. If the signal is triggered, timing is cleared, the relay remains on; when the signal disappears, the relay will be off when the “OP” time is over; if another signal is triggered during timing, timing will be cleared. How to choose the time interval: parameter Introduction: OP power over time, turn off time CL, LOP cycle times (1-999 times, “—” is unlimited cycle) In the selection of parameter set interface mode, and press the STOP button to select the time. (1)xxx. if the decimal point is in some place, the time interval is s-1 999 s (2)xx. x is the decimal place is ten, the time interval is 0.1 s 99.9 s- (3)x. x. x is the decimal point are all on, the time interval is 1 min-999 min How to set the parameter: First, make sure relay operation mode According to the operating relay mode, the main interface (power module will flash current operating mode; standard mode P1.1, then come into the main interface); long press SET key two seconds and then choose and enter selection interface mode; by pressing UP, DOWN key to choose the mode setting  (P1.1 ~ P4) After selecting the mode, press short SET to set the corresponding parameter, then the parameter you want to set will flash (OP power in time; CL power off time; LOP cycle times, “—” is unlimited cycle ); by UP, DOWN to set the parameter value, support long press (increase or decrease quickly) and press slightly (increase or decrease of 1 unit); after setting the parameter value by short press the STOP key to choosing decimal place; choose the time interval (corresponding time interval is 0.1 s-999 min); Short press SET to set the current mode next parameter, the process is the same as above After the setting mode parameter, press and hold the SET button then hold the current configuration mode will flash, then go back to the main interface; define success parameter main interface: when the relay does not work, it will show “000” (no decimal point); the operating state relay, the screen has a decimal point Mode Select Interface: press and hold the SET key to enter; after setting, long-press the SET button back on the main interface Activate Relay Mode: NO: PO in power over time, the relay can be connected OFF: relay is not allowed to connect, when in the off state in short main interface press the STOP key to achieve turn ON and OFF, the current state will flash; then back to the main interface (this function is a function of a sudden stop, 1 key to turn off the relay) Sleep Mode: C-P Sleep mode: within 5 minutes, no operation; nixie tube will close auto display, and a function program well Note: Press and hold the STOP button for 2 seconds can achieve change from C-P to O-d; Current state will flash and then return to the main interface The relay contact is passive and electricity production; 1 channel has the control function on / off
