We developed a custom solution for the AMG11S25T1024 encoder, intended for hazardous-area rotary feedback systems where multiturn absolute position tracking must operate together with 1024-pulse TTL incremental feedback. This configuration combines SSI absolute data transmission with TTL pulse output in a solid shaft Ø11 mm structure, providing a balance between usable pulse rate and signal sensitivity. It is not a high-margin configuration. It is a controlled signal design where wiring quality defines usability.
Typical production lead time: 15 working days.

Signal usability at this interface level depends directly on the structure, cable routing, and installation quality shown here.
System Limits
This configuration is limited by SSI timing stability and TTL signal integrity, not by mechanical capability.
The absolute channel depends on stable SSI clock and data synchronization. The incremental channel uses 1024 TTL pulses, which reduces frequency load compared with 2048 versions but still requires controlled signal conditions. The system does not fail because of shaft load or rotation speed. It fails when TTL signal edges degrade or when SSI timing becomes unstable.
Priority of limits:
- TTL signal integrity becomes unstable before mechanical limits are reached
- SSI synchronization determines whether absolute data remains usable
This configuration is limited entirely by signal quality and controller input capability, not by encoder structure.
Installation and Wiring Constraints
Electrical installation determines whether this encoder can function correctly.
- TTL signals require clean edge transmission and low-noise environment
- Poor shielding introduces signal distortion
- Grounding errors affect signal reference stability
Field boundary:
- Long cable without proper shielding → controller cannot interpret pulses correctly
- High-noise environment → incremental feedback becomes unreliable
- Unstable SSI clock → absolute data transmission fails
TTL output is more sensitive than HTL. Installation discipline is required.
Replacement and Interface Mapping
- Only valid when system supports SSI absolute input and TTL incremental input
- Suitable for applications requiring moderate pulse feedback with absolute reference
- Not applicable in high-noise or long cable environments
- Interface and connection can be adapted
Delivery and Customization Scope
Customization is available for interface, connection, and mounting structure.
