The SOP KTR2-R-50 is a compact, spring-return linear potentiometer displacement sensor providing a 5KΩ analog resistance output for precise 0-50mm position measurement. Designed for industrial automation, it integrates directly with PLCs, DAQ systems, and 3.3V/5V microcontroller ADCs for reliable motion feedback.

Features

  • High-precision 0-50mm linear displacement measurement with ±0.05% linearity.
  • Spring-return mechanism ensures consistent contact and eliminates manual resetting.
  • Rugged anodized aluminum housing with IP65 rating for dust and water resistance.
  • Long-life design rated for over 30 million mechanical cycles in demanding environments.
  • Simple DIN-standard cable connection for easy integration into control systems.

Description

The SOP KTR2-R-50 operates on a precision resistive potentiometer principle, where the linear displacement of the stainless steel rod directly alters the wiper position on a 5KΩ conductive track. This provides a continuous, infinite-resolution analog resistance signal proportional to position. The integrated return spring ensures the rod retracts automatically, making it ideal for reciprocating or push-to-measure applications.

Engineered for industrial durability, its anodized aluminum body and robust internal construction withstand significant vibration and impact. The sensor’s wide operating temperature range of -40°C to +80°C and IP65 ingress protection allow for reliable performance in harsh factory floor, automotive testing, or outdoor automation environments.

Key Features

  • Spring self-recovery linear potentiometer for automatic rod retraction.
  • Compact 18mm x 18mm cross-section housing for space-constrained installations.
  • Exceptional measurement repeatability of less than 0.01mm.
  • Extended mechanical lifespan exceeding 30 million cycles.
  • IP65-rated enclosure provides dust-tight and water-jet resistant protection.
  • Vibration and impact-resistant design for stable operation in industrial settings.
  • DIN-standard contact point with pre-attached cable for simplified wiring.
  • No complex push-rod alignment required for installation.

Applications

  • Industrial cylinder position feedback and stroke monitoring in pneumatic/hydraulic systems.
  • Precision gate or valve position sensing in process control and water management.
  • Automotive suspension travel measurement and testing rig position feedback.
  • Packaging machinery for monitoring linear actuator position and repeatability.
  • Robotic end-effector position verification and limit detection.

Frequently Asked Questions

What is the output signal of the KTR2-R-50 sensor and how do I interface it?

The sensor provides a pure analog resistance output, nominally 5KΩ across its full 50mm stroke. To read it, connect it as a variable resistor in a voltage divider circuit powered by ≤28V DC. The resulting voltage can be measured by a PLC analog input module or a microcontroller's ADC pin (e.g., on Arduino, Raspberry Pi, or ESP32) for position calculation.

What does the 'spring return' or 'self-recovery' mechanism mean for installation?

The integrated return spring automatically retracts the stainless steel measurement rod to its zero position when external force is removed. This eliminates the need for a separate return mechanism in your application, simplifies mounting alignment, and makes the sensor ideal for measuring reciprocating motion or objects that push against the rod.

Is the KTR2-R-50 suitable for outdoor or wet environments?

Yes, its IP65 rating provides protection against dust ingress and low-pressure water jets from any direction. This makes it suitable for use in damp industrial environments, washdown areas, or outdoor applications, provided the electrical connections are properly sealed according to the IP65 standard.

What is the expected lifespan and how does vibration affect performance?

The sensor is rated for over 30 million mechanical cycles, ensuring long-term reliability in continuous operation. Its robust construction with an anodized aluminum housing and secure internal components is specifically designed to resist external vibration and impact, maintaining stable electrical contact and measurement accuracy in dynamic industrial settings.
