Led Combo (R-G-Y-B-W) 5mm LEDs are used as indicator lamps in many devices and are increasingly used for other lighting. It looks like a white LED and illuminates blue light. When a light-emitting diode is switched on, electrons are able to recombine with holes within the device, releasing energy in the form of photons. This effect is called electroluminescence and the colour of the light (corresponding to the energy of the photon) is determined by the energy bandgap of the semiconductor. It is good quality and durable & small size and super bright LEDs with Low heat dissipation, energy-saving, and a long lifespan. These LEDs are always in demand in the DIY community as well as in industrial applications. Applications: DIY LED projects School science experiments Automobile decorations Electronic and electrical experiments

LJ12A3-4-Z/BX NPN 24V Approach Sensor Inductive Proximity Switch This Tube Type Inductive Proximity Sensor Detection Switch NPN DC5-36V 4mm Normally Open switch LJ12A3-4-Z/BX is a component widely used in the automatic control industry for detecting, controlling, and non-contact switching. When the proximity switch is close to some target object, it will send out a control signal. When the metal approaches the near-proximity switch sensing area, an Edy Current is induced in the metal. Which in turn disturbs the magnetic field produced by the Inductive Proximity Sensor. This change is sensed by the sensor. These inductive proximity switches can be non-contact, no pressure, no spark, quickly issued the electrical command. Accurately reflect the position and stroke movement mechanism. Positioning accuracy, operating frequency, service life. Easy to install and suitable for harsh environments. This 4mm proximity sensor can detect a variety of metals, miniature size, long life, low price, shielded type installation, anti-interference ability, 1mm detection distance, used for precise positioning of molds, precision machine tools, and robots. check out : Tube Type Inductive Proximity Sensor Detection Switch NPN DC5-36V 4mm Normally Open switch LJ12A3-4-Z/BX Applications: It is a component widely used in automatic control industry for detecting, controlling, and noncontact switching. It's widely used in machiness, paper making, light industry for limiting station, orientation taking counts, speeding trials, etc. Also, read our blog Types of Proximity Sensor detailing 5 types of proximity sensors and their working principles.

LJ12A3-4-Z/BY PNP DC 6-36V 4mm Tube Type Inductive Proximity Sensor Switch The LJ12A3-4-Z/BY inductive proximity sensor is a reliable and compact component designed for precise non-contact detection of metallic objects. Operating on a DC 6-36V PNP configuration, this 4mm tube-type sensor provides accurate positioning and fast response, making it ideal for industrial automation applications. When a metal object enters the sensing area, the inductive proximity sensor generates an Eddy Current that alters its magnetic field, allowing it to issue a quick electrical command without physical contact. With features such as long service life, excellent anti-interference capability, and easy installation, the LJ12A3-4-Z/BY is well-suited for use in molds, precision machine tools, robotics, and other demanding environments where reliability and durability are crucial. Features: A red LED indicates the proximity sensor's status. High repeatable positioning precision. High switching frequency. Wide voltage range. The whole length of the cylinder is 62mm. Thread length: 40mm. Outer (thread) diameter: M12. Antivibration, dust, water, and oil protection Reverse power protection, short circuit protection, and direct connection with PLC. Can replace tiny and limit switches.

LJ18A3-8-Z-BX 8mm Inductive Proximity Sensor The LJ18A3-8-Z/BX proximity sensor will detect large metal fields at an 8mm distance with great precision. This allows you to accurately measure the distance to an (aluminum) heated bed for example. If you are using a glass plate as your print surface, you can use aluminum foil right below the glass, which will also be detected by the sensor (mirrors however are not detected). The sensor is equipped with a small red detection LED, indicating a nearby object. The sensor has M18 threading and includes a nut for easy mounting to your 3D printer or CNC machine. The LJ18A3 is a PNP Normally Open (NO) type of proximity sensor. This means that the signal lead will output a positive voltage (same as the input voltage) when a metal mass is detected. When nothing is detected, the signal is equal to ground. Most modern 3D printer firmware has some sort of auto bed leveling procedure available, but you will need to enable it. You can use this sensor as the z_min_endstop for example, replacing your current end stop. Most firmware will also use the min end stop as a probe, but some allow a separate probe to be defined. This sensor operates at 5-36V, so as the signal voltage is the same as the input voltage, also the signal will be 5-36V. You will need to down-convert the voltage to an acceptable level for your electronics. Please see the linked schematic on how to connect this sensor to the end stop pins of your electronics board.
