Frequently Asked Questions

Q: What does "8421C BCD Positive Code" mean for a rotary encoder switch?

A: BCD (Binary Coded Decimal) 8421C is a standard encoding format where each decimal digit is represented by a 4-bit binary number using the weights 8, 4, 2, and 1. "Positive code" means the output is in standard (non-inverted) logic. This makes the 8421C rotary encoder switch easy to interface with most digital circuits, microcontrollers, and PLCs without the need for additional signal inversion.

Q: Can I use this rotary encoder switch with an Arduino or Raspberry Pi?

A: Yes! The 16-bit rotary encoder switch with 8421C BCD output is compatible with Arduino, Raspberry Pi, and most other microcontroller platforms. Simply connect the output pins to your digital input pins and read the BCD value to determine the selected position (0–F). It's a popular choice for setting addresses, modes, or parameters in embedded projects.

Q: What is included in the package?

A: Each package includes 1 piece of the 16-bit (0-F) rotary encoder switch with handle. No additional components or tools are required for basic installation.

Q: Is this switch suitable for panel mounting?

A: Yes, this rotary encoder switch is designed for panel mounting applications as well as PCB installation. Its compact 3:3 configuration and integrated handle make it a great choice for instrument panels, control boxes, and enclosures.
