LJ12A3-4-Z/BX Inductive Proximity Sensor Features Proximity sensors are used to detect the presence of nearby objects. The LJ12A3-4-Z / BX sensor has three pins, two of which are connected to a supply voltage of 6 to 36 V. The output pin is PNP and NO (Normal Open). That is, it is normally Low and when it detects an object, it becomes HIGH. The detection distance is 4 mm, and it can only detect metal objects such as copper, aluminum, iron, etc. Note Since the operation voltage is more than 5 V,...

4-bit Button Touch Proximity Sensor Features This module has 4 fingerprint touch inputs and 4 digital output pins. It also has 5 LEDs. One for power supply and 4 LEDs indicate fingerprint sensors. If you touch each sensor, the output becomes HIGH and the LED turns on. If you don’t touch, the output will be LOW and the LED turns off.This module can be used on glass, ceramic, plastic and other surfaces. 4-bit Button Touch Proximity Sensor Pinout This module has 6 pi...

TTP223 Capacitive Touch Sensor Features The TTP223 sensor can be used in a variety of applications such as smartphones and tablets. The sensor can recognize objects even from behind glass and thin surfaces. The operating voltage is 2 to 5.5V. The maximum response time is 220 milliseconds. This module has two non-soldered adjustment pins: A and B. The working modes are as follows:A and B both open: The default value of the output pin is LOW. When the sensor is subjected to touch, the output is HIGH, and...

OMRON Photoelectric Sensor Features The Omran photoelectric sensor can be used to detect obstacles and objects at 5 to 100 mm distance. There is an LED on the sensor that is always off and turns on when it detect an obstacle. You can also change the LED status using the potentiometer which is on sensor. (That is, the LED is always on and will turn off when the obstacle is detected.) There is another potentiometer on the sensor that can be used to change the sensitivity of the sensor (increase or decrease th...

SS49E Linear Hall Effect Sensor Features The output of SS49E linear Hall sensor provides an analog voltage representing if a magnetic field is present. So, this small and versatile sensor can be used in systems containing permanent magnets or an electromagnets in order to monitor magnetic field change. The output voltage is in the range of 2.25V to 2.75V. In this sensor, amplifier, voltage regulator and logic switching circuits are used to overcome noise in the output. SS49E Linear Hall Effe...
