New dual-shaft concentric encoders with pushbutton from ELMA available

**Leo Bodnar** · 04-29-2009, 12:15 PM

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!
