以下是CKD-RO磁性开关的产品中英文介绍：

CKD-RO磁性开关是一种通过磁铁感应来实现开关功能的电子元件。其工作原理是利用磁场信号来控制线路的通断，当有磁性物质靠近时，开关内部的簧片会被磁化而互相吸引接触，从而使电路连通；当磁性物质远离时，簧片则因本身的弹性而分开，电路断开。

该磁性开关具有多种特点。在材质方面，有PP、PVDF材质可适用于强酸碱场所，SUS 304/316金属材质则适用于温压桶槽。其接线盒规格齐全，有塑料、铝合金、不锈钢型，防护等级可达IP-65以上。接点容量为50W/250VAC SPST或30W/200VDC SPDT。此外，它还可以做多点控制，安装容易，能节省成本。

在技术参数上，CKD-RO磁性开关的工作电压范围为5-240V DC/AC，最大开关电流为100mA，最大开关容量为10W。内部消耗电流无，残留压降为2.5Vmax@100mA，泄漏电流也为无。其指示灯为红色LED，电缆线为灰色耐油PVC电缆。灵敏度为60Gauss，最大开关切换频率为200Hz，使用温度范围为-10~+70℃，耐冲击为30G，耐振动为9G。

CKD-RO磁性开关广泛应用于气缸活塞运动位置的确认及定位，也可用于化工、石油、地矿、能源、道路/轨道/船舶等领域。其价格因生产厂家、规格型号等因素而有所不同。例如，湖北杭荣电气有限公司提供的CKD-RO磁性开关价格合理，且规格齐全。此外，麻城施迈赛工业自动化有限公司也是专业的CKD-RO磁性开关生产厂家，上海五久自动化设备有限公司也提供该产品。

The CKD-RO magnetic switch is an electronic component that operates by sensing magnets. It works on the principle of controlling the circuit s continuity based on magnetic field signals. When a magnetic material approaches, the reed inside the switch is magnetized and attracts each other to make contact, thus completing the circuit. Conversely, when the magnetic material moves away, the reeds separate due to their inherent elasticity, breaking the circuit.

This magnetic switch boasts a variety of features. In terms of materials, it is available in PP and PVDF, which are suitable for strong acid and alkali environments, while SUS 304/316 metal materials are appropriate for temperature and pressure tanks. The switch has a comprehensive range of wiring box specifications, including plastic, aluminum alloy, and stainless steel types, with a protection rating of IP-65 or higher. It has a contact capacity of 50W/250VAC SPST or 30W/200VDC SPDT. Moreover, it can be used for multi-point control, is easy to install, and can save costs.

Regarding technical parameters, the CKD-RO magnetic switch has a working voltage range of 5-240V DC/AC, a maximum switch current of 100mA, and a maximum switch capacity of 10W. It has no internal consumption current, a residual voltage drop of 2.5Vmax@100mA, and no leakage current. The indicator light is a red LED, and the cable is a gray oil-resistant PVC cable. The sensitivity is 60Gauss, the maximum switch switching frequency is 200Hz, the operating temperature range is -10~+70℃, the shock resistance is 30G, and the vibration resistance is 9G.

The CKD-RO magnetic switch is widely used for confirming and positioning the movement of cylinder pistons, as well as in fields such as chemical engineering, petroleum, geology, energy, roads/tracks/ships, etc. The price of CKD-RO magnetic switches varies depending on the manufacturer, specifications, and other factors. For example, Hubei Hangrong Electric Co., Ltd. offers CKD-RO magnetic switches at reasonable prices with a full range of specifications. Macheng Schmersal Industrial Automation Co., Ltd. is also a professional manufacturer of CKD-RO magnetic switches, and Shanghai Wujiu Automation Equipment Co., Ltd. also provides this product.
