Overview

The A6A-10R is a subminiature rotary coded switch from Omron that provides a 10-position BCD output. It is designed for PCB mounting with a 2.54mm pitch and features a compact 10mm length for high-density layouts. This switch allows for manual hardware configuration by converting rotary position into a 4-bit Binary Coded Decimal logic signal.

Why Choose This Part

This switch supports a wide voltage range from 5V to 28V DC and handles output currents up to 100mA, making it compatible with both logic-level circuits and higher voltage industrial controllers. Its gold-plated twin contacts ensure high contact reliability and longevity in demanding environments.

Applications

Node Addressing
Assigning unique ID numbers to industrial sensor nodes or actuators on a shared communication bus.
Configuration Settings
Setting operating modes, baud rates, or hardware parameters without requiring an external interface.
Limit Adjustments
Defining threshold levels or timer intervals in control systems where a physical interface is preferred for reliability.

Getting Started

Integrate the switch into your PCB using the standard 2.54mm pitch footprint and 7.62mm row spacing. Connect the common terminal to your supply voltage and use pull-down resistors on the four BCD output pins to interface with your microcontroller GPIOs. Ensure your firmware includes a brief debounce routine to handle mechanical transitions between switch positions.
