How Challenging is Your Environment?

Hazardous Environments

The TopWorx GO Switch is designed to function where high temperature, pressure, radioactivity and potential for combustion are constant challenges. In addition to high temperature +204 °C (+400 °F), cold temperature -50 °C (-58 °F), and sub-sea 7,010 m (23,000 ft) applications, these products are suitable for use in Flameproof/Explosion Proof, Non-Incendive, Intrinsically Safe hazardous areas with both global and regional certifications available.

A Versatile Combination of Proximity Switch and Limit Switch

The TopWorx GO Switch uses magnets to detect a ferrous metal or magnetic target, and like other proximity switches has no exposed, moving parts. Like a limit switch, it provides highly precise readings and is suitable for a wide variety of industrial applications. By combining these features, the GO Switch requires far less maintenance than traditional limit switches and performs within ruggedized and harsh environments that often prohibit the use of other technologies such as inductive or capacitive sensors.

方形 TopWorx GO 开关是传统机械限位开关的理想替代产品。通常用于要求精度略低、有侧面和端部感应变化的延伸感应应用。两块内部磁体（其中一块为主导）影响支持密封触点的电枢位置。进入感应区域的铁质或磁性目标会转移磁通量场，使另一个磁体成为主导，致使电枢闭合触点后产生信号。
