    Lightbulb New dual concentric encoders with pushbutton and matching knobs from ELMA available

    Hello everyone!

    I have found that ELMA introduced new Mechanical Dual Concentric Encoder Type E37 in the last quarter of 2008 and I wanted to give it a try. If anyone is interested - I have 18 sets left to sell. I apologise for commercial nature of this post but I think this is important enough to be interesting to quite a few builders! So...

    Dual concentric: Two encoders
    16 detents on both axes
    With integrated push button
    Excellent indexing feel with 2.5 Ncm switching torque (remains consistent over life)
    Matching knobs
    11.5 x 12.3 x 9.1 mm body size
    Made in Switzerland

    Model number is E37-VT6330-1. Encoders datasheet.

    Matching knobs. Knobs datasheet.
    21mm light-grey matt knob 020-4415
    14.5mm light-grey matt knob 020-3315
    Matt light-grey cap for 14.5mm knob 040-3015
    I believe the knobs are easily paintable if needed but I can't give 100% guarantee.

    Knobs have internal locking system (collet) that clamps the shaft without side locking screw. It looks very tidy and solid.

    Overall, the build quality is excellent - it is a proper aeronautical part.
    Comparison to ALPS EC11EBB24C03:
    Life-span. ELMA-300,000 ALPS-15,000
    Panel-mounting nut: ELMA-yes ALPS-no
    Detents: ELMA-16/16 ALPS-30/30
    Detent torque: ELMA-2.5Ncm ALPS-1.0Ncm
    Shaft diameters: ELMA-4mm/6mm ALPS-3.5mm/6mm
    Pushbutton: ELMA-yes ALPS-yes
    Typical Applications: ELMA-[Cockpit controls/radios and navigation] ALPS-[Home DVD audio/video , home appliances, car AV equipment]
    Work with BU0836/A/X controllers range: ELMA-yes ALPS-yes

    Bare encoder with nut - 14.99
    Set of knobs (14.5mm, 21mm, cap) - 4.99

    Due to cost of this encoder and it is being new to the market I offer full refund (less postage) if it is returned unused in original condition. I doubt anybody will - it is a keeper!

    Please keep the discussion here but email me leobodnar@leobodnar.com if you want to order.

    Thank you if you have made it this far!
