Encoders – 62D22-01-P Application Field and Working Principle

Encoders are versatile yet essential components for various industries, as they can be used for motion control, vital machine diagnostics, and other automated applications. Encoders today can be found in a variety of fields, from automotive manufacturing to health services. The 62D22-01-P is a specific industrial grade incremental 14-bit quadrature encoder regarded highly for its compact size, versatility, and affordable price. It is thereby a popular choice for a wide range of industries.

Application Field

The 62D22-01-P encoder can be identified by its miniature size as it typically measures 58 mm in diameter and 34 mm in height. As a result, it can be conveniently used for tight spaces and low profile applications. It features a 1 Vpp quadrature output, a 4-bit serial output, and a 240 CPR, allowing for a variety of solutions. It is usually commonly used for feedback applications in the following industries:

• Automotive and transportation
• Aerospace
• Healthcare applications
• Industrial automation
• Packaging and machine tooling

Working Principle

The 62D22-01-P encoder uses a brushless DC actuator for its design. This type of actuator eliminates the need for springs and permanent magnets, resulting in a smoother and more accurate operation. The encoder measures the position of the displaced shaft using its track-mounted sensing device, translating it into a voltage signal. This signal is then sent to the hydraulic valve, providing the feedback information.

The 62D22-01-P encoder further features a PWM (Pulse Wave Modulation) technique which increases the response speed by applying four-bit discrete output. This feature also allows for higher resolution due to its variable pulse widths. It is the combination of these features which has made the 62D22-01-P encoder a popular choice among various industries.

Conclusion

In conclusion, encoders have become essential components as they allow for considerable automation and precision control potentially for a variety of solutions across multiple industries. The 62D22-01-P is a particularly versatile quadrature encoder due to its compact size and the application of the PWM technique. Despite its affordable cost, the encoder is well-regarded for its accuracy and responsive performance, thus providing an attractive solution for industries requiring a reliable encoder.
