Description

The SOP KTR2-R-25 utilizes a precision resistive potentiometer sensing element to provide continuous, infinite-resolution feedback on linear position. The built-in spring return mechanism ensures the rod retracts automatically, making it ideal for applications where direct push-rod alignment is impractical or where cyclical motion is required.

Engineered for industrial environments, the sensor features a compact 18x18mm anodized aluminum housing and a corrosion-resistant stainless steel rod. The IP65 protection rating guards against dust ingress and water jets, while the double-bearing design enhances stability and minimizes the effects of vibration and side loads, ensuring signal integrity from -40°C to +80°C.

Key Features

  • High-Precision Sensing: Delivers ±0.05% linearity across the full 25mm stroke for critical position control.
  • Robust Mechanical Design: Anodized aluminum body and stainless steel rod withstand harsh industrial conditions.
  • Spring-Return Mechanism: Integrated spring ensures positive return without requiring external force, simplifying installation.
  • Environmental Durability: IP65 sealing protects against dust and water ingress for reliable operation.
  • Long Service Life: Mechanical construction rated for over 30 million cycles, minimizing maintenance downtime.
  • Wide Temperature Range: Operates reliably from -40°C to +80°C for use in extreme environments.
  • Simple Analog Interface: 5KΩ resistive output easily interfaces with PLC analog input modules or microcontroller ADCs.
  • Compact Form Factor: Small 18x18mm housing profile allows for installation in space-constrained locations.

Applications

  • Precision position feedback for hydraulic and pneumatic cylinder rod extension
  • Stroke monitoring and limit detection in automated packaging and assembly machinery
  • Valve position sensing and control in process automation systems
  • Thickness and gap measurement in industrial testing and quality control stations
  • Feedback for linear actuators and servo mechanisms in robotics

Frequently Asked Questions

What is the output signal of the KTR2-R-25 sensor and how do I interface with it?

The sensor provides a 5 kΩ analog resistive output. To read the position, connect the sensor as a variable resistor in a voltage divider circuit powered by a stable DC voltage (e.g., 5V or 24V). The wiper voltage can then be measured by a PLC analog input module, data acquisition system, or microcontroller ADC pin to determine the linear displacement.

Does this sensor require an external power supply?

Yes, the sensor itself is a passive resistive element. It requires an external excitation voltage to be applied across its terminals to generate a measurable output voltage proportional to position. The system is compatible with standard 24VDC industrial control voltages, but the actual voltage applied for measurement should be within the ratings of your readout device.

What is the purpose of the spring return mechanism?

The built-in spring return mechanism automatically retracts the stainless steel push rod when the external force is removed. This ensures the sensor returns to its zero position reliably, which is critical for cyclical applications like reciprocating machinery, valve actuation, or any system where the measured object does not provide a positive return force.

Is the included 1m cable directly solderable or does it have a connector?

The product includes a 1-meter cable that is typically pre-attached to the sensor body. The cable ends are usually stripped and tinned for direct connection to terminal blocks or soldering into your control system. The specifications do not indicate a removable connector; it is a cable-type electrical connection for permanent installation.
