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.

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.

Quad Operational amplifiers IC.

The LM139 series consists of four independent precision voltage comparators with an offset voltage specification as low as 2 mV max for all four comparators. These were designed specifically to the operation from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage. The LM139 series was designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, they will directly interface with MOS logic— where the low power drain of the LM339 is a distinct advantage over standard comparators. These devices consist of four independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Operation from dual supplies also is possible, as long as the difference between the two supplies is 2 V to 36 V, and VCC is at least 1.5 V more positive than the input common-mode voltage. Current drain is independent of the supply voltage. The outputs can be connected to other open-collector outputs to achieve wired-AND relationships. The LM139 and LM139A are characterized for operation over the full military temperature range of –55°C to 125°C. The LM239 and LM239A are characterized for operation from –25°C to 125°C.
