E3F3-DS50P1 M30 Diffuse Reflection DC Three-Wire PNP Normally Open Photoelectric Switch 50cm

Description

The E3F3-DS50P1 is a diffuse reflection photoelectric switch designed to detect objects up to a maximum distance of 50 cm. This type of switch uses reflected light from an object to activate an electrical circuit. Features: Type – Diffuse Reflection Photoelectric Switch, Power Supply Voltage – DC (check datasheet), Output Type – PNP, Default State – Normally Open, Detection Distance – 50 cm, Number of Wires – 3 What is it for? The E3F3-DS50P1 is ideal for automatic control applications such as door or window opening and closing. It can also be used to create simple alarm systems by connecting it to an electric bell. Its compatibility with Arduino and other microcontrollers makes it a versatile solution for home automation and robotics projects. Tutorial: How to use E3F3-DS50P1 The diffuse reflection photoelectric switch E3F3-DS50P1 is ideal for controlling door or window opening and closing. Useful for beginners and intermediates, it simplifies the creation of alarm systems. What you need – Arduino UNO or compatible, 1 kΩ resistor, DC power cable, power connector Steps: 1. Connect the photoelectric switch to the Arduino board via the three-wire connection. 2. Attach a 1 kΩ resistor between ground and the output pin (VCC) of the switch. 3. Connect the VCC pin of the switch to 5V on Arduino. 4. Connect the GND pin of the switch to the ground of Arduino. 5. Load the provided Arduino code. 6. Test the switch: move it towards and away from the reflection barrier. 7. Check the datasheet for further details. 8. Configure the switch for your project. Example Code “` void loop() { if (digitalRead(2) == HIGH) { Serial.println(“Open”); } else { Serial.println(“Closed”); } }“` Mini-project Create a simple alarm system by connecting the switch to an electric bell. In 30 minutes, you can mount the switch, connect it to a bell and program the alarm. Common mistakes Not checking connections before powering the switch. Connecting VCC pin to 3.3V instead of 5V. Omitting pull-down resistor. Not consulting datasheet for further details.
