LEINE LINDE ISA608 881801-01 ENCODER WITH WDS 2500 P85 M SO MEASURING 2500MM SN 6461 12:57

1. Product Name & Model:

• Manufacturer: Leine & Linde (A Swedish manufacturer renowned for high-performance, heavy-duty encoders used in demanding industrial applications).

• Product Series/Model: ISA608

• Part Number: 881801-01 (The specific article number for this encoder configuration).

• Key Feature: WDS 2500 P85 M SO (This decodes to the Wire Draw Sensor (WDS) with a 2500mm long wire, plus specific mechanical and electrical options).

2. Key Features & Functionality:

• Core Purpose: This is an absolute encoder integrated with a wire draw sensor (WDS), also known as a cable extension transducer or string pot. It is designed for linear position measurement.

• How It Works:

  1. A stainless steel cable (the “measuring wire”) is extended from and retracted into the unit.

  2. As the cable moves, it turns the spindle of the integrated rotary encoder.

  3. The encoder translates the rotational movement into a high-precision digital or analog signal that represents the linear position.

• “MEASURING 2500MM”: This specifies that the stroke length of the cable is 2500 millimeters (2.5 meters). This is the maximum distance it can measure.

• “WDS 2500 P85 M SO”: This is a crucial product code that defines the specifics:

  • WDS: Wire Draw Sensor.

  • 2500: 2500 mm stroke length.

  • P85: Likely refers to the specific drum and spring mechanism model.

  • M: Often indicates a Modular design, meaning the encoder module can be separated from the WDS mechanism.

  • SO: Almost certainly specifies the output signal. SO typically stands for “Sin/Cos 1 Vpp” analog output. This is a high-resolution analog format that can be interpolated by a downstream device (like a PLC drive card) for extremely precise position data.

• “ISA608”: This indicates a robust, industrial-grade encoder housing with a specific flange size and shaft configuration.

• “SN 6461”: The unique Serial Number for this specific unit.

3. Technical Specifications (Inferred from Standard Leine & Linde Models):

• Linearity: Very high accuracy (e.g., ±0.05% of full stroke is common for this grade).

• Resolution: The Sin/Cos (SO) output allows for theoretically infinite resolution, limited only by the interpolating electronics.

• Speed: Designed for high cable extraction/retraction speeds.

• Construction: Built for harsh environments, typically featuring a stainless steel housing, cable, and IP66 or IP67 sealing against dust and moisture.

• Electrical Connection: Likely a connector or cable outlet as specified by the “SO” option.

4. Intended Use & Context:
This is a premium-grade sensor used for critical linear positioning and measurement in challenging industrial environments. Common applications include:

• Mobile machinery (cranes, excavators, boom lifts) for measuring boom extension/angle.

• Industrial automation (presses, rolling mills, material handling) for precise position feedback.

• Test and measurement equipment.

• Forestry equipment.

• Marine applications (winch positioning).
