YL-99 Impact Limit Switch Module
YL-99 Impact Limit Switch Module is a compact collision detection sensor designed to detect physical contact, impact, or mechanical movement in electronic and robotics projects. The module uses a mechanical limit switch that changes its output state when triggered by an external force, allowing microcontrollers to detect collisions and object contact. Operating with a 3V to 12V power supply, it provides a simple digital output signal suitable for Arduino, ESP32, Raspberry Pi, STM32, and other development platforms. Its lightweight design, mounting holes, and reliable switching mechanism make it ideal for robotics, automation systems, and position detection applications.
وحدة حساس التصادم YL-99 هي وحدة استشعار مدمجة مصممة لاكتشاف الاصطدامات والتلامس الميكانيكي والحركة في المشاريع الإلكترونية والروبوتية. تعتمد على مفتاح حدّي ميكانيكي (Limit Switch) يغيّر حالة الخرج عند التعرض للضغط أو الاصطدام، مما يسمح للمتحكمات الدقيقة باكتشاف التلامس أو الوصول إلى نقطة معينة. تعمل بجهد يتراوح بين 3 فولت و12 فولت وتوفر إشارة رقمية سهلة القراءة بواسطة Arduino وESP32 وRaspberry Pi وغيرها. بفضل حجمها الصغير وسهولة تثبيتها، تعد مناسبة للروبوتات وأنظمة الأتمتة وتحديد المواقع والحواف.
The YL-99 Impact Limit Switch Module is a simple and reliable mechanical collision detection sensor designed for use in robotics, automation, and electronic control systems. The module incorporates a mechanical limit switch that generates a digital signal whenever physical contact or impact occurs.
When the switch is pressed, the output changes state, allowing a microcontroller or control circuit to detect a collision, object presence, or movement limit. This makes the module particularly useful for robot obstacle detection, travel limit sensing, position monitoring, and safety shutdown applications.
The module includes convenient mounting holes for easy installation and supports a wide operating voltage range from 3V to 12V, making it compatible with most embedded systems and development boards.
