Product Overview
The SAMSON 4746-12102100 Inductive Valve Position Limit Switch is designed for reliable monitoring and indication of valve travel positions in industrial process control systems. Manufactured by SAMSON, this instrument uses non-contact inductive proximity sensing to detect predetermined positions of a valve actuator. Its adjustable switching mechanism provides electrical signals when the valve reaches or passes a configured travel limit, supporting reliable valve position monitoring, alarm activation, and automated process control.
Part of the SAMSON Type 4746 Series, the 4746-12102100 belongs to the intrinsically safe inductive limit switch family designed for appropriately certified hazardous-area applications. Its aluminium housing, mechanical lever arrangement, and adjustable proximity switching elements support installation on compatible linear control valve actuators and SAMSON Type 4763 and 4765 positioners. The switch is suitable for valve travel monitoring in oil and gas processing, chemical plants, power generation, water treatment, and industrial manufacturing. The related 4746-032021 belongs to the electric limit switch configuration and should be maintained as a separate model.

How do I find the right part for my system?
Three options. Search by part number if you have the OEM code from Parker, Danfoss, Linde, Kawasaki, Kayaba or Grundfos — our search recognises both manufacturer codes and aftermarket cross-references. Browse by category if you know the component type (pumps, valves, cylinders, etc.). Or send a spec sheet to our engineering desk and we'll cross-reference against our 3,000+ SKU catalogue within one business day.
Can you help me size a pump or valve for my application?
Yes — sizing support is included with every order. Send us your operating pressure, flow rate, viscosity, drive speed and duty cycle, and our engineers will recommend a suitable component from our catalogue with full datasheets. We don't custom-build parts ourselves, but we can spec the right OEM component for almost any standard industrial application.
Can you cross-reference a discontinued part?
Yes — cross-referencing is one of the things we do most. Send us the original part number (even if the manufacturer has dropped it) and our engineering desk will identify a current equivalent or compatible alternative. Cross-reference lookups are free and typically come back within 4 business hours.
