We developed a custom solution for the AMG11S25T2048 encoder, intended for hazardous-area rotary feedback systems where multiturn absolute position tracking must be combined with TTL incremental feedback. This configuration integrates SSI absolute output with 2048-pulse TTL incremental signals, using a solid shaft Ø11 mm structure. It is selected when the system requires both deterministic position data and high-speed pulse feedback for motion control. It is not a high-margin configuration. It is a signal-sensitive dual-output design.
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 transmission. The TTL incremental channel introduces higher sensitivity to noise due to lower signal amplitude compared to HTL. The system does not fail because of shaft load or mechanical rotation. It fails when TTL signal edges degrade or when SSI synchronization cannot be maintained.
Priority of limits:
- TTL signal integrity fails before mechanical limits are reached
- SSI timing stability determines whether absolute data remains usable
This configuration is limited entirely by signal quality and system input capability, not by encoder structure.
Installation and Wiring Constraints
Electrical installation defines system reliability.
- TTL signals require strict noise control and clean edge transmission
- Poor shielding introduces signal distortion
- Grounding errors directly affect signal reference
Field boundary:
- Long cable without proper shielding → controller cannot interpret TTL pulses
- High-noise environment → incremental feedback becomes unstable
- SSI clock instability → absolute data transmission fails
TTL output is more sensitive than HTL. Installation quality must be higher.
Replacement and Interface Mapping
- Only valid when system supports SSI absolute input and TTL incremental input
- Suitable for applications requiring high-speed pulse feedback with absolute reference
- Not applicable in high-noise environments or long cable installations
- Interface and connection can be adapted
Delivery and Customization Scope
Customization is available for connection type, interface, and mounting structure.
