INDUCTIVE PROXIMITY SENSOR DETECTION SWITCH

Description

The Whadda inductive proximity sensor detection switch accurately detects metal objects that are within 4 mm of the sensor head. When a metal object is detected, the built-in red LED lights up and the black signal wire is internally shorted to ground through an NPN transistor. When no object is detected, the signal is floating/high impedance.

Note: It is recommended to supply the sensor with no more than 6 V, and to put a series protection resistor between the signal output of the sensor and digital input of your board when connected to 5 V logic, such as Arduino® compatible boards.

Features

• Broad voltage compatibility: This module operates reliably within a voltage range of 6 to 36 VDC, making it suitable for various electronic applications.
• Contactless Detection: This inductive proximity switch enables contactless detection of metal objects up to a distance of 4 mm, providing you with precise and reliable detection without physical contact.
• Versatile applications: This module is versatile and suitable for various applications, from automation, home automation and robotics to environmental and industrial monitoring.
• STEM project: Develop and improve your STEM skills and acquire the knowledge, skills and experience needed to face the technological challenges of the future with this educational kit. This educational kit will trigger a number of processes such as problem-solving, investigative and creative thinking.
• Made in Belgium: Whadda is a unique brand from Belgium’s Velleman Group that offers DIY projects for hobbyists or makers who want to immerse themselves in electronics, programming and mechanics.
• Remark: Power the sensor with a maximum of 6 V and use an optocoupler between the sensor’s output signal and the digital input of your board for connection to an Arduino® compatible board.
