Q & A
GO™ Switch Model 11 Limit Switch - Proximity Sensor Q & A
+What is the GO™ Switch Model 11 used for?
The GO™ Switch Model 11 is a rugged proximity limit switch used for reliable position sensing** in industrial automation systems. It detects ferrous metal targets without physical contact, making it ideal for applications such as valve position monitoring, pump control, conveyor detection, and other harsh industrial environments where mechanical limit switches may fail.
+What sensing distance does the Model 11 provide?
The standard sensing range is 3/8 inch (10 mm) side sensing, with an extended sensing option of 9/16 inch (14 mm), depending on configuration. The extended sensing distance allows engineers to detect moving metal targets at greater distances compared to many traditional limit switches.
+Is the GO™ Switch Model 11 suitable for hazardous areas?
Yes. The Model 11 is designed for hazardous industrial environments and carries approvals for Zone 0 and Zone 1 hazardous locations as well as Class I Division 1 and Division 2 areas. These certifications make it suitable for industries such as oil & gas, petrochemical processing, and chemical manufacturing.
+What temperature range can the Model 11 operate in?
The standard operating temperature range is -50°C to 105°C (-58°F to 221°F), with optional configurations capable of operating up to 176°C (350°F) for high-temperature applications. This wide range allows the switch to function reliably in extreme industrial conditions.
+What configuration options are available for the Model 11?
The GO™ Switch Model 11 can be configured with several options, including:
- DMDB Form Z or SPDT Form C contacts
- Latching contacts for maintained signaling
- 316L stainless steel housing
- Extended sensing range
- Terminal block, lead wire, or cable connections
- Quick disconnect connectors (Micro or Mini)
- Subsea connectors for offshore applications
These options allow engineers to tailor the switch for a wide range of industrial environments and installation requirements.
