Outdoor Proximity Sensor


Emerson has introduced the Topworx GO Switch Model 52M, a 12 mm proximity sensor designed specifically for applications in outdoor and challenging industrial environments. The new sensor is well-suited for material handling, mobile equipment, industrial equipment, and food and beverage processing applications.


The GO Switch 52M is highly durable, does not require power, and operates across a wide temperature range. The  sensor is ideal for OEMs desiring reduced maintenance and fewer equipment breakdowns. The GO Switch provides a much more rugged alternative to the inductive proximity sensor and is far more reliable than a reed switch.


The Model 52M incorporates the GO Switch’s unique dry contact proximity sensor technology that uses magnets to control a set of contacts. This technology’s durability and reliability have been proven in over 60 years of service in the process industries. 


  • No power requirement – provides application flexibility
  • High reliability – tested to 5 million cycles at full-rated load
  • Broad temperature range (-40 to 100°C) – allows use across multiple applications
  • Simple contact arrangement – enables highly flexible wiring schemes
  • Polarity insensitivity – eliminates need to specify NPN or PNP products
  • Weld-field immunity – for large magnet field applications
  • High and low current compatibility (5 mA to 2 A @ 24 VDC) – permits use with PLCs and
