Description
x📌 What OSE1024 Is
The OSE1024 is an incremental rotary encoder manufactured by Mitsubishi Electric, typically used as a spindle or feed encoder in CNC machine tools and servo systems. It provides relative position and speed feedback by producing electrical pulse signals as the shaft rotates.
🔧 Key Specifications
Model family: OSE1024-3-15 variants (e.g., OSE1024-3-15-68, OSE1024-3-15-68-8, OSE1024-3-15-160) — these suffixes refer to flange size and rated speed variations.
-
Type: Incremental optical rotary encoder
-
Output: 1024 pulses per revolution (PPR) incremental signal (A/B quadrature and often Z index)
-
Power supply: Typically 5 VDC input
-
Speed ratings:
-
~6000 rpm for standard 68 or 160 models
-
~8000 rpm for -68-8 variant
-
-
Mounting: Square flange (e.g., 68 mm or 160 mm) for secure installation on motor/spindle shafts
These encoders are often referred to as synchronous feed encoders because they provide precise relative pulses that the drive/controller can use to synchronize motion loops or spindle feedback.
🧠 How It Works
Incremental encoders like the OSE1024 output:
-
A-phase and B-phase pulses: Square waves in quadrature (90° phase shift), allowing the controller to detect rotational direction and count pulses for position/speed measurement.
-
Z (index) pulse: One pulse per revolution for reference/homing (if provided by the specific variant).
The controller counts these pulses to estimate relative shaft movement and speed — zeroing and absolute position require external reference or homing routines.
🛠️ Typical Applications
OSE1024 encoders are commonly used in:
-
CNC servo axes for precise motion control
-
Spindle speed/position feedback in machine tools
-
Feed encoders on motors requiring incremental pulse feedback
-
Positioning systems in automation where 1024 PPR is sufficient for control accuracy
Their relatively high pulse count (1024 PPR) provides fine granularity for many industrial applications without the complexity of absolute encoders.
⚙️ Summary
| Feature | Specification |
|---|---|
| Encoder Type | Incremental rotary (optical) |
