Buy online your Tekel TK561.F.2500.5.S.K5.10.PL30.LD Rotary encoder from our UK e-store Cnc-shopping UK, specialist in CNC machine-tools spare parts.

The TEKEL TK561.F.2500.5.S.K5.10.PL30.LD is an industrial rotary encoder designed to provide precise position and speed feedback for CNC machines, servo systems, and general motion control applications. It is commonly used as a replacement unit or spare part in maintenance operations where reliable encoder feedback is essential for machine performance and positioning accuracy.

Part of the TEKEL TK561 series, this model features a resolution of 2500 pulses per revolution (PPR), making it suitable for fine indexing, accurate speed regulation, and closed-loop positioning applications. The encoder generates clean quadrature signals with an index pulse, allowing CNC controls and servo drives to calculate shaft position and rotational speed with high precision.

The TK561.F.2500.5.S.K5.10.PL30.LD is equipped with a square flange and a 10 mm shaft configuration, ensuring compatibility with a wide range of servo motors, rotary tables, and spindle assemblies. It operates from a +5 V ±5% power supply and uses an RS422 line driver output based on the 26LS31 standard, providing excellent signal integrity over long cable distances and in electrically noisy industrial environments.

The encoder supports frequencies up to 100 kHz and offers bidirectional operation with an index reference pulse. It is protected to IP65 according to EN60529, making it suitable for installation in machine-tool environments exposed to dust, coolant mist, and industrial contaminants when correctly mounted.

This version is fitted with a radial cable gland and a factory-installed cable available in 3-meter lengths, simplifying installation and replacement procedures. The suffixes included in the complete part number define the exact mechanical and electrical configuration specified by the original equipment manufacturer, making it important to match the full reference when ordering a replacement unit.

Manufactured in Italy, the TEKEL TK561 series is recognized for its robust construction and stable signal quality. It is frequently used on CNC feed axes, spindle orientation systems, rotary indexing tables, automated handling equipment, and other applications requiring precise rotational feedback.

Each unit can be tested on dedicated encoder test benches or CNC simulators to verify resolution, phase relationship, and index pulse operation before shipment. Products are packaged using protective materials suitable for industrial transportation and are supplied with standard warranty coverage. Repair services, exchange programs, and urgent sourcing options may also be available depending on stock and application requirements.

Frequently asked questions about TK561.F.2500.5.S.K5.10.PL30.LD:

How do I confirm compatibility with my drive or controller?
Match the full code on your current encoder against TK561.F.2500.5.S.K5.10.PL30.LD and verify resolution, output interface, supply voltage, shaft size and connector pinout. Share the nameplate or machine documentation and our team can validate the fit.

What does the 2500 value indicate on this encoder code?
It identifies a resolution of 2500 pulses per revolution. This value must align with the motion controller requirements and the machine parameters configured in your CNC system.

Can I substitute a different suffix if only the resolution matches?
Mechanical and electrical suffixes define shaft, mounting and signal options, so a like-for-like replacement is recommended. Changing suffixes without verification can lead to misfit or interface mismatch.

Do you support refurbished or exchange options for urgent needs?
Depending on availability, refurbished unit and exchange service options can be proposed to shorten repair turnaround. All units are functionally tested prior to dispatch.
