中文介绍
美国HAMLIN哈姆林品牌的MDCG-4干簧管是一种微型常开磁簧开关,其玻璃外壳尺寸仅为15.24mm×2.28mm,小巧的体积使其能够轻松安装在空间受限的设备中。这种开关采用玻璃封装,内部填充惰性气体,触点被密封在其中,完全不受外界环境影响,从而确保了其长期稳定的工作性能和较长的使用寿命。
MDCG-4干簧管能够在10W的功率下开关200VDC电压,其灵敏度范围为7AT-43AT,能够满足不同应用场景对磁场感应灵敏度的要求。它具有10¹⁰Ω的高绝缘电阻以及低于100mΩ的接触电阻,保证了电路的稳定性和可靠性。此外,该开关的触点动作所需功率几乎为零,在节能方面表现出色。
MDCG-4干簧管广泛应用于多种领域,包括簧片继电器、安全系统、计量设备、限位传感、通信设备、办公设备等。例如,在安全系统中,它可以作为门窗传感器,用于检测门窗的开关状态;在家电领域,可用于冰箱门控等场景。
English Introduction
The MDCG-4 reed switch from HAMLIN, a U.S. brand, is a sub-miniature normally open reed switch. It features a glass envelope measuring only 15.24mm in length and 2.28mm in diameter, making it ideal for installation in devices with limited space. The switch is hermetically sealed in a glass enclosure filled with inert gas, ensuring that the contacts are not affected by external environmental factors. This design contributes to its long-term stability and extended service life.
The MDCG-4 reed switch is capable of switching 200Vdc at 10W. It offers a sensitivity range of 7AT-43AT, allowing it to meet the varying magnetic field sensitivity requirements of different applications. With a high insulation resistance of 10¹⁰ ohms and a contact resistance of less than 100 milliohms, it ensures stable and reliable circuit performance. Additionally, the switch requires almost zero operating power for contact closure, making it energy-efficient.
The MDCG-4 reed switch finds extensive applications in various fields, including reed relays, security systems, metering equipment, limit sensing, telecommunications, and office equipment. For example, in security systems, it can be used as a door or window sensor to detect the opening and closing status of doors and windows. In the home appliance sector, it is suitable for applications such as refrigerator door control.
