Global Leading Market Research Publisher QYResearch announces the release of its latest report “Incremental Quadrature Rotary Encoder – Global Market Share and Ranking, Overall Sales and Demand Forecast 2026-2032″. Based on current situation and impact historical analysis (2021-2025) and forecast calculations (2026-2032), this report provides a comprehensive analysis of the global incremental quadrature rotary encoder market, including market size, share, demand, industry development status, and forecasts for the next few years.
For motion control engineers, automation system integrators, and robotics designers, the core challenge in closed-loop feedback is achieving precision motion control with accurate angular displacement and speed detection, while balancing cost, resolution, and environmental robustness. Incremental encoders without quadrature output cannot determine direction (only count pulses); absolute encoders provide position but at higher cost and complexity. Incremental quadrature rotary encoders address these pain points by outputting two pulse signals (Channel A and Channel B) offset by 90° phase difference, enabling the controller to determine rotation direction based on phase lead/lag. These angle measurement devices are widely used in CNC machine tools, robotic joints, motor control, and automated transmission systems, providing high-resolution counting capabilities (up to tens of thousands of counts per revolution via edge counting on both channels). The upstream market relies on optoelectronic components (LED/phototransistor pairs for optical encoders), magnetic sensors (Hall elements for magnetic encoders), PCB substrates, and precision mechanical parts (bearings, shaft couplings). The downstream market includes industrial automation equipment manufacturers, robotics companies, and motor/drive control system manufacturers. As global industrial automation expands and servo motor penetration increases (CAGR 8–10% in industrial robots), demand for incremental quadrature rotary encoders grows. Understanding the market dynamics between 10 PPR, 12 PPR, 15 PPR, 20 PPR, 24 PPR, and other pulse-per-revolution (PPR) resolutions becomes essential for matching encoder cost to application accuracy requirements.

PPR Resolution Segmentation: 10 PPR, 12 PPR, 15 PPR, 20 PPR, 24 PPR, and Others
The report segments the incremental quadrature rotary encoder market by pulse-per-revolution (PPR) resolution—a key determinant of positional accuracy and counting methodology (×1, ×2, or ×4 edge counting). Lower PPR devices are cost-optimized for speed measurement; higher PPR devices provide finer angular resolution.
10 PPR (≈15% of Market Value)
10 PPR encoders output 10 pulses per revolution on each channel. Using quadrature decoding (×4 edge counting = 40 counts per revolution), they achieve 9° of angular resolution—sufficient for cost-sensitive speed sensing (conveyor belts, fan speed monitoring) but inadequate for precision positioning. Applications include simple factory automation and industrial fans. Sparkfun and Rotalink offer economical 10 PPR encoders (6–10).Anotableusercase:InQ42025,apackagingmachinerymanufacturerdeployed12,00010PPRencodersoncaseerectorlineshaftsforspeedfeedback(6–10).Anotableusercase:InQ42025,apackagingmachinerymanufacturerdeployed12,00010PPRencodersoncaseerectorlineshaftsforspeedfeedback(9/unit), achieving required accuracy at 60% cost of 24 PPR alternatives.
12 PPR (≈12% of Market Value)
12 PPR encoders produce 12 pulses/revolution; ×4 edge counting yields 48 counts/revolution (7.5° resolution). Used in elevator door openers, treadmill speed sensing, and light-duty conveyor positioning. Bourns and Grayhill supply through-distribution channels. Market stable (CAGR 3.5%), losing share to higher PPR as component costs decline.
15 PPR (≈14% of Market Value)
15 PPR encoders (60 counts/rev ×4 = 6° resolution) are common in automotive sensors (electronic throttle control, EGR valve position) where cost and temperature range (-40°C to +125°C) matter more than ultra-fine resolution. Sensata and TE Connectivity supply AEC-Q100 qualified versions.
20 PPR (≈16% of Market Value, Fastest-Growing for General Automation)
20 PPR (80 counts/rev ×4 = 4.5° resolution) balances cost and precision for general machine automation (CNC tool changers, indexing tables, pick-and-place). US Digital and Broadcom B40 series compete in this resolution band. A user case: In Q1 2026, a Chinese robotics manufacturer standardized on 20 PPR encoders for SCARA robot wrist joints (requiring 0.5mm positioning, achieved with 4:1 gear ratio), saving $4.20 per unit vs. 24 PPR while meeting spec.
24 PPR (≈18% of Market Value, Fastest-Growing for Servo Control)
24 PPR encoders (96 counts/rev ×4 = 3.75° resolution) offer finer angular measurement for premium applications: servo motor feedback (position loops every 125 microseconds), collaborative robot joints, and high-precision rotary tables. High-resolution counting capability allows interpolation to sub-degree positioning. Omron, Panasonic, and Broadcom lead this segment. A notable user case: In Q4 2025, a European machine tool builder upgraded 10,000 servo drives from 20 PPR to 24 PPR encoders, reducing contouring error in 5-axis CNC by 40% (from 8 μm to 5 μm) for aerospace blisk production.
Other PPR (≈25% of Market Value)
Includes 1–5 PPR (very low resolution, single-turn absolute-like counting for door/window position), 30 PPR, 36 PPR, 50 PPR, 100–400 PPR (high-resolution for medical robots and semiconductor equipment), and 500–5,000 PPR (direct-drive in precision stages). High-PPR optical encoders (Broadcom AEDR series, US Digital) command $25–60 pricing.
Application Deep Dive: Industrial Robots, Automation Equipment, Automotive Electronics, and Others
- Industrial Robots (≈38% of market value, largest segment): Articulated robot joints (6–7 axes per robot), SCARA, delta, and collaborative robots (cobots). Precision motion control requires encoders on each joint for torque control and trajectory tracking. While many robot OEMs use absolute encoders (multiturn) for main position, incremental quadrature encoders are used on auxiliary axes (conveyor tracking, tool changers) and lower-cost cobot designs (<25kpricepoint).JTEKT,Joral,andUSDigitalsupplyrobotics−destinedencoders.Ausercase:InQ32025,acobotstartupdeployed15PPRencodersonallsixjointsofits25kpricepoint).JTEKT,Joral,andUSDigitalsupplyrobotics−destinedencoders.Ausercase:InQ32025,acobotstartupdeployed15PPRencodersonallsixjointsofits19k cobot, achieving ±0.1 mm repeatability (×4 edge counting + 15:1 harmonic drive gear), saving $360 per robot compared to absolute encoders.

Exclusive Industry Observation: Edge Counting Interpolation and Resolution Enhancement
Unlike absolute encoders (direct digital word per position), incremental quadrature rotary encoders achieve precision motion control through quadrature decoding interpolation—significantly enhancing effective resolution beyond native PPR. A critical technical practice and purchasing decision: ×1, ×2, or ×4 edge counting:
- ×1: Count only rising edges of Channel A → resolution = PPR (coarse, direction ambiguous on some controllers).
- ×2: Count both rising/falling edges of Channel A → 2× PPR counts/revolution.
- ×4: Count rising/falling of both A & B → 4× PPR counts/revolution (most common for industrial servo drives).
Thus, a 24 PPR encoder with ×4 decoding yields 96 counts/revolution (3.75° resolution). A 100 PPR with ×4 gives 400 counts/rev (0.9°). Most motion controllers (Siemens, Rockwell, Beckhoff) default to ×4 decoding for maximum resolution. However, counter register overflow limits resolution: for a 32-bit counter (2,147,483,647 max), a 400 PPR encoder with ×4 (1,600 counts/rev) overflows after 1.34 million revolutions—acceptable for most applications.
In 2025, a manufacturer discovered that low-cost microcontrollers sampling A/B at 10 kHz can miss edges at >3,000 RPM (with 100 PPR, 2,000 pps = insufficient bandwidth). Solution: angle measurement devices with dedicated encoder counter hardware (e.g., NXP FlexTimer, TI eQEP) cost $2–5 more per microcontroller but support 100,000 pps input (sufficient for 100 PPR × 60,000 RPM). This hardware-peripheral availability explains why system-on-chip (SoC) integrated encoders cost less than discrete incremental quadrature encoder counters in high-speed applications.
