The Heschen M18 Capacitive Proximity Sensor offers a reliable and cost-effective solution for achieving precise auto bed leveling on your 3D printer. This non-shield type sensor boasts adjustable sensitivity, making it a versatile choice for various build surfaces, including your steel sheet build plate.What Makes It Stand Out:Accurate Bed Leveling: This sensor provides accurate and consistent readings, enabling your 3D printer to precisely determine the distance between the nozzle and the print bed. This results in improved first layer adhesion, reduced print failures, and overall enhanced print quality.Adjustable Sensitivity: The adjustable sensitivity is a key feature that sets this sensor apart. It allows you to fine-tune the sensing distance to accommodate different build plate materials and thicknesses, including your steel sheet. This versatility ensures optimal performance across various setups.Wide Voltage Range: The sensor operates within a wide voltage range (DC 6-36V), making it compatible with most 3D printer control boards.Durable Construction: The sensor has a metal housing, which provides durability and protection against everyday wear and tear in the 3D printing environment.Cost-Effective Solution: This sensor offers excellent value for its price, making it an attractive option for budget-conscious makers who want to upgrade their 3D printer with auto bed leveling without breaking the bank.Important Considerations:*Firmware Update Required: As you mentioned, using this sensor requires updating your 3D printer's firmware. For Marlin systems, you'll need to reflash the firmware with the necessary configuration changes to enable the sensor. On Klipper, an update is required to integrate the sensor into your setup.Wiring: Ensure you have the appropriate wiring and connectors to connect the sensor to your 3D printer's control board.Overall:The Heschen M18 Capacitive Proximity Sensor is a highly recommended upgrade for 3D printer enthusiasts seeking reliable and affordable auto bed leveling. Its adjustable sensitivity, wide voltage range, and durable construction make it a versatile and valuable tool for achieving precise and consistent print results. While a firmware update is necessary, the improved print quality and ease of use make it a worthwhile investment for any 3D printing enthusiast.

静電容量の変化を感知するセンサーを備えており、センサー部分に何か近づくものがあり、静電容量が変化して、閾値を超えれば スイッチの状態が変化するものですね。タッチしてもいいのですが、タッチまでいかない非接触の状態でも静電容量は変わるので、非接触のタッチセンサーとして使えるわけです。メカニカルな部分がないのと、センサーに近づくのは 指でももちろん反応しますが、容量が変わればいいので、通電しないガラスでも、液体の水面でも反応させることができます。3線式なので、センサーの動作電源を独立に提供することができます。配線の色が独特ですね。茶: 電源+ 青: 共通GND 黒:スイッチ状態 加える電源電圧と、センサーの反応距離には関係があります。高電圧の方が センサーから遠くても反応します。5V ぐらに電圧からスイッチとして動作し始めます。安定化電源とオシロスコープで動作を確認しました。

Leider ging er nach wenigen Monaten kapput. Anfangs immer ungenauer dann plötzlich garnicht mehr. Leider kaum ein halbes Jahr alt.
