Description

The SOP WPS-S-R-500 is a robust rope displacement sensor, also known as a string potentiometer, utilizing a resistive belt measurement system. As the cable extends or retracts, the internal potentiometer provides a corresponding change in resistance, enabling accurate tracking of linear position. The sensor’s voltage distribution output ensures a stable analog signal proportional to the cable extension.

Engineered for demanding industrial environments, the unit features a sealed IP65 enclosure that protects the internal mechanism from dust and water jets. Its wide operating temperature range and durable aluminum alloy construction guarantee reliable performance in automation, material handling, and motion control applications where precise, long-stroke linear feedback is critical.

Key Features

  • Draw-wire (rope) type linear displacement sensor with 500mm stroke.
  • Analog 5KΩ resistive potentiometer output for simple voltage divider circuits.
  • High measurement accuracy and excellent long-term repeatability.
  • IP65-rated housing provides protection against dust and water jets.
  • Durable aluminum alloy construction for mechanical robustness.
  • Extended service life rated for up to five million operational cycles.
  • Compact design facilitates installation in space-constrained applications.
  • Includes 1-meter output cable for direct electrical connection.

Applications

  • Industrial automation for monitoring actuator extension and retraction.
  • Material handling equipment for measuring conveyor belt travel or lift height.
  • Machine tool positioning and feedback in CNC or robotic arms.
  • Gate, door, or hatch position monitoring in heavy machinery.
  • Test and measurement rigs for precise linear displacement recording.

Frequently Asked Questions

What is the output signal of the SOP WPS-S-R-500 sensor?

The sensor provides a 5 kΩ analog resistance output. As the cable extends or retracts, the resistance changes linearly with position. This output is typically used in a voltage divider circuit with an external supply voltage (13-30V DC) to produce a proportional voltage signal for your PLC, DAQ system, or microcontroller ADC.

What is the IP rating and what environmental conditions can it withstand?

This sensor is rated IP65. The '6' indicates complete protection against dust ingress, and the '5' means it is protected against low-pressure water jets from any direction. This makes it suitable for industrial environments with dust, dirt, or occasional water spray, but it is not designed for continuous immersion or high-pressure washing.

How do I mount and install this draw-wire displacement sensor?

The sensor is designed for easy bracket or panel mounting using the provided accessory set. Ensure the mounting surface is stable and the cable can extend/retract freely without Sharp Microelectronics bends or obstructions. The 1-meter attached cable provides the electrical connection; wire it into your measurement circuit according to the voltage divider principle using the specified supply voltage range.

Can the stroke length or output type be customized?

Yes, the manufacturer SOP offers customization for stroke length, physical size, and output signal type (e.g., different resistance values, voltage, or 4-20mA). For custom requirements, you must contact the supplier or manufacturer directly with your specific application needs, as the standard unit is configured as described.
