101-7801-6
by Sanyo Denki
The Sanyo Denki 101-7801-6 is a precision encoder from the High Accuracy Absolute Encoders series, designed for industrial automation and motion control applications. This brushless resolver–type encoder operates on 10-15 V AC input and delivers exceptional ±15 arc-seconds angular precision. Featuring an operating temperature range of -40 °C to +125 °C, it maintains reliable performance under extreme environmental conditions. Its primary function is to provide accurate position and speed monitoring in demanding industrial systems.
In terms of technical specifications, the 101-7801-6 outputs complementary sine and cosine signals at ±15 V, supporting frequency responses up to several kHz for high-speed feedback. The encoder sustains an insulation resistance of over 1 GΩ at rated voltage, ensuring electrical integrity and long-term stability. With a maximum rotational speed of 6000 rpm and a minimal starting torque below 0.01 N·m, it rapidly detects angular changes without introducing significant mechanical load. The compact mechanical dimensions (58 mm diameter × 40 mm length) and lightweight design (200 g) facilitate integration into tight assemblies while the brushless resolver architecture minimizes maintenance and wear.
Additional features include IP65 environmental protection, guarding against dust ingress and water jets, making it suitable for harsh industrial settings. Its low power consumption (<2 W) and consistent output current (10 mA) contribute to overall system efficiency and reduce thermal buildup. The encoder complies with industrial insulation and environmental standards, ensuring safe operation in automated lines and robotics. By incorporating the 101-7801-6 into machinery, engineers benefit from superior accuracy, robustness, and long service life, optimizing throughput and reducing downtime in critical production processes.
