All-in-One Solution – Dual Encoder Kit for Flight Simulator

Our Dual Rotary Concentric Encoder Kit offers everything you need to bring professional functionality to your flight simulator panels. This complete set includes a dual-shaft EC11 encoder with integrated push button, premium anodized aluminum knobs for both shafts, and a ready-to-use PCB with pin connectors for a clean and reliable installation.

Why choose our Dual Encoder Kit?

• All-in-One Package: Encoder, knobs, and PCB in one kit – no need to source parts separately.

• Threaded Design: The EC11 encoder body comes with a machined thread for secure and easy panel mounting.

• Professional Finish: Anodized aluminum knobs ensure durability and a polished look.

• Effortless Connectivity: PCB with pin headers eliminates the hassle of soldering, making setup faster and cleaner.

• Perfect for Simulation: Ideal for building G1000 panels or custom avionics in MSFS, X-Plane, and other flight simulators.

Inspired by ELMA E37 – Complete Kit at a Fraction of the Cost

We know the ELMA E37 is highly regarded for dual concentric control, but its price and limited availability can be a barrier. Our EC11-based kit provides an excellent alternative:

• Dual concentric shafts with integrated push button

• Includes anodized knobs and dedicated PCB for easy wiring

• Secure threaded mounting for simulation panels

• Available at ~1/6 of the ELMA E37 price, with consistent stock and fast shipping

If you’re looking for ELMA E37-level usability in a ready-to-install kit, our solution is the most accessible way to upgrade your cockpit.

• The EC110703P6C-HA1 can be used with any controller that operates at 5V DC or lower, including:

  • Arduino (Uno, Mega, Leonardo, etc.)
  • Leo Bodnar (BU0836, BU0836A, BU0836X)
  • Microchip PIC and Atmel AVR-based microcontrollers
  • Raspberry Pi (with voltage level shifting)
  • STM32 and ESP32 (with 5V-tolerant inputs)
  • Other flight simulation and automation interfaces

  ⚠️ Ensure that the operating voltage does not exceed 5V DC, as higher voltages may damage the encoder.

1. FAQ – Dual Encoder Kit (Encoder + Knobs + PCB)

   Knobs (Inner & Outer)

   What material are the knobs made of?

   • Black anodized aluminum for high durability and a professional finish

   What are the shaft dimensions?

   • Inner shaft: Ø 3.5 mm (knob external Ø 11 mm)

   • Outer shaft: Ø 6 mm (knob external Ø 15 mm)

   What fastening system do the knobs use?

   ---

   PCB with Pin Connector

   Does the PCB come with the connector pre-soldered?

   • No. The 6-pin connector is not pre-soldered, giving flexibility to solder directly or use wires.

   What are the pin functions?

   • BTN → Push button output

   • A (Outer) → Outer encoder signal A

   • B (Outer) → Outer encoder signal B

   • A (Inner) → Inner encoder signal A

   • B (Inner) → Inner encoder signal B

   • COM → Common ground (for button and both encoders)
