Encoder customization for your equipment

FLUX offers encoder modifications and custom solutions for equipment manufacturers. Share the available installation space, the required connection to your control system and the number of units you expect to need. FLUX will review what can be customized and confirm any minimum order quantity before the project proceeds.

Match the feedback to the environment.

Bring mounting, contamination and interface requirements into the model review.

What to bring to the discussion.

A drawing is useful. A well-defined requirement is a starting point too.

01
Required accuracy, repeatability and resolution
02
Absolute or incremental output requirement, controller interface and mounting envelope
03
Temperature, contamination and electromagnetic environment
04
Prototype needs and expected annual volume

Manufacturer references

Encoder accuracy, interfaces and protection ratings depend on the selected product. Incremental A/B/Z configurations are available across the GMI and inductive encoder families. IP67 is model-specific; confirm the chosen encoder and installation. OEM customization and suitable production volume require manufacturer review.

FLUX encoder selection

Absolute position. Defined interfaces. Verified protection.

Technical terms to confirm for the selected encoder
Requirement	Manufacturer documentation	Integration question
Absolute encoder	GMI and IND-MAX families provide absolute position measurement.	Which position information does the controller require?
Incremental output	Incremental A/B/Z configurations are available across GMI-ANGLE, GMI-ROTARY, IND-MAX and IND-ROT encoder families, alongside model-specific absolute BiSS/C and SSI options.	Which ordering code and electrical interface match your controller?
IP67 protection	Listed for GMI-ROTARY and the encapsulated IND-MAX design.	Does the selected product and installation meet your environmental requirement?

Review the GMI-ROTARY datasheet, revision 03, pages 10 and 30 and IND-MAX product information. Specifications are tied to those families; they are not a blanket rating for every FLUX product.

Maximum absolute output resolution by FLUX family
Encoder family	Maximum output resolution	Manufacturer reference
GMI-ANGLE	25 bits (GMI-ANG250)	GMI-ANGLE datasheet
GMI-ROTARY	23 bits	GMI-ROTARY datasheet
IND-MAX	23 bits	IND-MAX datasheet
IND-ROT	22 bits output; up to 20 bits effective resolution (ENOB)	IND-ROT datasheet

Resolution is not accuracy. Maximum values apply to specific sizes and configurations; effective resolution depends on mounting conditions.
