58 mm Incremental Rotary Encoders (Sine Wave, Shaft Type) E58S (Sine Wave) Series

Product Overview

The E58S series sine wave incremental rotary encoders are engineered to deliver precise analog sine wave operational amplifier (op-amp) outputs, ideal for both speed regulation and position control. The C and D output phase signals allow for accurate calculation of absolute position, while the A and B output phase signals can be multiplied to achieve high precision position control, rivaling encoders with over 10,000 pulses.

Key Features

• Tapered Shaft DesignThe E58S series encoders are equipped with a tapered shaft, designed to provide secure and reliable operation in various applications.
• Analog Sine Wave OutputThese encoders utilize an operational amplifier (OP Amp) to transmit precise analog sine wave signals, enhancing control accuracy.
• High Resolution and PrecisionWith a resolution of 2,048 pulses per revolution (PPR), the E58S series offers highly detailed position feedback. The ability to multiply A and B phase signals ensures precision control comparable to encoders with much higher resolutions.
• Robust Environmental ToleranceThe encoders are built to withstand harsh conditions, operating effectively within a temperature range of -20 to 100°C and a humidity range of 35 to 85%RH. They also have vibration and shock resistance to ensure durability in demanding environments.
• Versatile Connection OptionsAvailable in both axial and radial cable types, the E58S series encoders provide flexibility for various installation scenarios.
