The “LJ12A3-4-Z/BX” is an inductive proximity sensor that detects metal objects within a 4mm range. It operates on a DC 6-36V power supply and has an NPN (Normally Open) digital output, meaning it completes a circuit to the signal line when it detects metal. These sensors are used in industrial automation for non-contact switching, control, and detection
5mm 5537 LDR is a 5mm light-dependent resistor with a “5537” model number, which is a photosensitive component that changes its electrical resistance based on the intensity of ambient light. Its resistance is high in darkness and decreases as light increases, making it useful for light-sensitive applications like automatic lighting systems, alarms, and light-level detection.
This is 125K RFID Tag. The RFID technology is used for sensing and identifying tagged people and objects for access control, automation, and a whole range of different applications.
Operating on a frequency of 125kHz, these tokens are all pre-programmed with unique ID numbers to communicate wirelessly with RFID Readers over distances of around 10cm or less. This means you can attach it to vehicles or items, keyrings or even pets’ collars to keep track of the location via an array of readers in the office, warehouse or home.
