Mitsubishi Spindle Encoder TS5690

📌 What TS5690 Is

TS5690 is a spindle-side high-resolution PLG serial output encoder (position detector) made by Mitsubishi Electric, used in CNC and drive systems to provide precise spindle position and speed feedback for advanced motion control such as C-axis control and synchronous tapping. It outputs high-speed serial signals for the controller/drive to decode.

🧰 Key Features

• Encoder Type: PLG Serial Output Encoder — meaning it sends encoded position data via a high-speed serial interface rather than simple A/B pulses.

• Used For:
  ✓ C-axis orientation control
  ✓ High-accuracy synchronous tapping
  ✓ Spindle speed/position detection when the spindle is not directly coupled to the motor (e.g., belt or gear reduction).

📊 Technical Specifications

The TS5690 series comes in different variants (e.g., TS5690N64xx, TS5690N12xx, TS5690N25xx) that differ mainly in resolution, detection gear, and cable length: 

🔹 Series Types & Detection Gear Options

• TS5690N64xx

  • Uses detection gear with 64 teeth

  • Detection resolution: ~2,000,000 pulses/rev

  • Tolerable speed up to 40,000 rpm 

• TS5690N12xx

  • Uses detection gear with 128 teeth

  • Detection resolution: ~4,000,000 pulses/rev

  • Tolerable speed up to 20,000 rpm

• TS5690N25xx

  • Uses detection gear with 256 teeth

  • Detection resolution: ~8,000,000 pulses/rev

  • Tolerable speed up to 10,000 rpm

📏 Other common specs

• Z phase pulse: 1/rev for indexing.

• Signal interface: Mitsubishi high-speed serial output.

• Cable lengths: Typically available from 400 mm up to 2000 mm options (determined by model suffix).

• Encoder construction: Includes a sensor head (TS5690) and a matching detection gear (MU1606 series) that attaches to the spindle.

🛠️ Typical Application

The TS5690 encoder is installed on the spindle side (often on the spindle shaft or corresponding gear) and provides real-time position and speed information to the CNC controller or spindle drive. It’s especially useful in systems where precise spindle orientation and timing are critical — for example:

• C-axis machining

• Rigid and synchronous tapping

• High-precision spindle positioning in gear/belt-driven spindles

Compared with basic ABZ pulse encoders (like the OSE-1024 series), TS5690 offers much higher resolution and serial communication, enabling smoother high-speed and high-accuracy manufacturing tasks.

📌 Summary

TS5690 is a Mitsubishi high-resolution, PLG serial output spindle encoder, used mainly for advanced CNC motion control (C-axis, synchronous tap, speed/position feedback) where high precision is required. It integrates a sensor and a detection gear to output serial position data to drive/controllers, and comes in various resolution and cable length configurations.
