Encoders are a type of rotary position sensing technology, which is often used to provide feedback data to a control system or component on the positioning of a rotary actuated object such as a motor or servo. H38D-12GC-28V/V-CW-SC-CEN is a type of optical encoder which is widely used in various applications.

Overview

The H38D-12GC-28V/V-CW-SC-CEN is a 12-bit optical incremental encoder with continuous and self-clearing code wheels. It is featured with a hollow shaft design, 28V/V DC voltage output and a linearity of up to ±1 counts. The H38D-12GC-28V/V-CW-SC-CEN provides a maximum operating frequency of 12MHz and a maximum operating speed of 30,000 RPM. It offers excellent durability and reliability with high shock and vibration resistance capabilities. Additionally, the working temperature range of the encoder is -40°C to +100°C.

Electrical Connections

The H38D-12GC-28V/V-CW-SC-CEN uses a M12 8-pole connector for electrical connections. This connector consists of eight slots with four signal output slots (two for A, B, Z) at 2 o’clock, 8 o’clock, 10 o’clock, and 4 o’clock. Two supply slots (for +Vcc and GND) at 3 o’clock and 9 o’clock, and two redundant slots (for A’, B’, Z’) at 11 o’clock and 5 o’clock. The encoder is compatible with a variety of different signals.

Application Fields

The H38D-12GC-28V/V-CW-SC-CEN is used in various industrial applications such as motor speed control, robots and other automated machinery, conveyors systems, test stands, and CNC machining. It is also commonly used in medical equipment such as medical imaging systems, dental chairs, and physiotherapy devices. Moreover, this encoder can be used in the automotive industry for positioning precision motors of various functional elements.

Working Principle

H38D-12GC-28V/V-CW-SC-CEN optical encoder uses an internal code wheel with transparent and opaque lines arrayed around its circumference. As the shaft is rotated, the code wheel casts light pulses through the transparent lines onto an array of photodiodes located behind the code wheel. This creates a set of pulses that the photodiodes transform into an electrical signal, which is then transmitted to the control system. This electrical signal is processed by the control system to obtain the required information for position, direction, and speed/distance.

Advantages

H38D-12GC-28V/V-CW-SC-CEN optical encoder offers a number of advantages over traditional encoders. The main advantage is the ability to measure infinite angle increments with a greater degree of accuracy. This is due to the fact that the encoder uses photodetectors to measure the position of the code wheel. Additionally, the high resolution and frequency output of the encoder makes it ideal for applications that require precise positioning. Furthermore, the encoder is built for high reliability and can withstand harsh environmental conditions.

Conclusion

H38D-12GC-28V/V-CW-SC-CEN optical encoder is a highly reliable and accurate encoder for a number of applications, ranging from industrial automation to medical imaging systems. It offers a very high resolution and frequency output as well as excellent shock and vibration resistance capabilities. This makes it the ideal choice for positioning precise motors with speed, direction, and position feedback control.
