GXM7W.1102101 RS485 Multiturn Absolute Encoder Custom Solution

We designed a custom encoder solution for model GXM7W.1102101, targeting RS485 communication, optical multiturn feedback, and a compact Ø58 mm housing with 1 m radial cable output for installations where rear axial space is limited. The platform offers 13 bit singleturn resolution, 12 bit multiturn capacity, and supports clamping or synchro flange structures for different mechanical layouts. Typical production lead time: 15 working days.

Technical Key Parameters

• Resolution: 13 bit (8192 steps)
• Multiturn range: 4096 turns
• Interface: RS485
• Supply voltage: 10...30 VDC
• Absolute accuracy: ±0.025°

Wiring and Installation Notes

The encoder is built around an RS485 bus structure with separated signal IN/OUT lines for orderly multi-node connection. For line lengths above 10 m, the communication pairs should be wired as twisted pairs to reduce interference risk. The final user on the bus requires an external 150 Ω termination resistor. The encoder platform also provides UP/DOWN direction input and zero setting input, with zero setting activated by a high-level impulse longer than 100 ms. In installation practice, the radial cable outlet is often easier to route when axial depth is limited, but cable bending stress should still be minimized near the housing exit.

Custom Compatible Encoder Solution

• RS485 signal and communication matching
• 1 m radial cable output arrangement
• Support for 13 bit ST + 12 bit MT absolute feedback
• Customization available for cable routing, mechanical fit, and protocol definition
