Liquid Level Sensor | Mini Non-Contact Switch | XKC-Y23A Model

The XKC-Y23A is a small non-contact liquid level sensor with adjustable sensitivity. Its small size makes it easy to put in tight spots. This sensor finds liquids through non-metallic container walls. It gives a simple high/low level output for your projects. Features and Benefits - Adjustable sensitivity with an automatic calibrate button. This lets you fine-tune the sensor for different container thicknesses (up to 13mm) and various liquids. - Small 18mm diameter size. This small water level detector fits easily into devices like a coffee machine or smart pet feeder. - Non-contact operation keeps liquids clean. You can safely find water, mild acids, or other harsh liquids without the sensor ever touching them. - Available with NPN or high/low level output. Choose the XKC-Y23A NPN output for relays or the 5V high/low output for direct connection to a microcontroller. Applications - Small appliance design: Add boil-dry protection or empty-tank indicators to compact devices. - Laboratory equipment: Check fluid levels in beakers or reservoirs without risk of contamination. - Custom automation: Build a non-contact water level detector switch for a hydroponics system or other DIY project needing level control. Mechanical Ball / Rolling-Element Switches (Simple On/Off) These tilt sensors operate on a simple principle, often involving a rolling element like a ball or mercury within an enclosure. When the sensor is tilted beyond a certain angle, the rolling element moves, making or breaking an electrical connection. This provides a basic on/off switch output. They are effective for applications where a straightforward indication of tilt or no-tilt is required. The product described is a Non-contact Liquid Level Switch with an Adjustable Sensitivity, providing a Switch Output Type rather than a mechanical tilt detection. MEMS Accelerometers (Precise Angle Measurement) Micro-Electro-Mechanical Systems (MEMS) accelerometers are sophisticated devices that can measure acceleration in multiple axes. By detecting changes in acceleration due to gravity, they can determine precise tilt angles. This allows for continuous angle measurement rather than just an on/off state. They are commonly used in applications requiring accurate orientation sensing. The Y23A Model is a Capacitance Sensor for liquid level detection, and does not have Tilt Sensor Functionality. Optical Tilt Sensors Optical tilt sensors utilise light to detect changes in angle. This can involve a light source and detector, where the path of light is interrupted or altered by a moving element as the sensor tilts. The change in light detected then correlates to the tilt angle. They can offer high precision and non-contact operation. The Y23A Model uses a Non-contact Detection Method, but its Theory is Capacitance Sensing for liquid level. Quick Comparison - Mechanical Ball / Rolling-Element Switches: Simple on/off, robust, cost-effective for basic tilt detection. - MEMS Accelerometers: Precise angle measurement, continuous output, suitable for detailed orientation sensing. - Optical Tilt Sensors: High precision, non-contact, often used where mechanical wear is a concern. The product, a Mini Non-Contact Liquid Level Switch, operates on Capacitance Sensor Theory with Adjustable Sensitivity and provides a Switch Output. Its primary function is liquid level detection, not tilt measurement. The Gravity Sensor A "gravity sensor" is a general term often used to describe sensors that detect the Earth's gravitational field. In the context of tilt, this typically refers to accelerometers which measure the component of the 1g gravitational force acting on different axes. By analysing these forces, the sensor can determine its orientation relative to gravity, thus indicating tilt. The product is a Liquid Level Sensor with a Non-contact Detection Method and Capacitance Sensor Theory, designed for detecting liquid levels, not for measuring tilt based on gravity.
