SAS IntelliLink® — Encoder Signal Converter
Convert any encoder signal to any output protocol — engineered for your exact need.
The SAS IntelliLink™ Encoder Bridge accepts any encoder input — TTL/HTL pulse, 1 Vpp Sin/Cos, SSI, BiSS-C, EnDat or Resolver — and converts it cleanly to the output protocol your drive, controller or CNC system requires. Each device is custom-built, tested and tuned by SAS engineers specifically for your application. No generic modules, no programming required on your side.

Signal Conversion
From any encoder input — to any protocol output.
The Encoder Bridge sits between your existing encoder and your target system. It receives the signal your encoder produces, converts it internally, and outputs the exact protocol your drive, CNC or controller expects. No signal adaptation on your side, no re-wiring of the machine.

Each hardware version is a fixed input–output combination. You select your input type and your required output — we build the corresponding unit.
How It Works
Three steps from your encoder to your controller.
You don’t need to understand encoder protocol conversion, signal timing or differential line driver standards. You just need to know what goes in and what needs to come out — we handle the rest.
1. Tell us your signals
What encoder do you have? What protocol does your drive, CNC or controller require as input? That’s all we need. We identify the correct conversion and specify the version for you.
2. We build your version
Every Encoder Bridge is a fixed-input, fixed-output hardware unit engineered for your specific signal combination. It is assembled, programmed and tested by SAS engineers before dispatch.
3. Install and run
Wire the unit between your encoder and your controller. The Encoder Bridge converts the signal transparently — your target system sees exactly the encoder protocol it expects.
Supported Inputs
Which encoder signals can we accept?
The Encoder Bridge handles every common encoder interface type found in industrial, CNC and motion control environments.

Supported Outputs
Which output protocol does your system need?
The Encoder Bridge outputs the protocol required by your target drive, CNC or controller — with no additional interface hardware needed on the receiving end.
| Output Protocol | Description | Typical Target System |
|---|---|---|

Fanuc Ready Compatibility
Fanuc Ready for CNC integration.
The differential A/B/Z output of the SAS IntelliLink Encoder Bridge is Fanuc Ready. This makes the Encoder Bridge an ideal solution when a machine carries a non-standard encoder type — Sin/Cos, BiSS-C, SSI, EnDat or Resolver — but the CNC system expects a Fanuc-compatible incremental encoder input.
Legacy encoder modernisation
Existing machine carries an older encoder type. Instead of replacing the encoder and rewiring the machine, the Encoder Bridge adapts the signal to what a Fanuc-ready interface expects — same encoder, new CNC.
Multi-brand encoder integration
Third-party encoder with a non-Fanuc native interface (e.g. 1 Vpp or BiSS-C). The Encoder Bridge converts transparently so Fanuc-ready CNC systems see standard incremental feedback.
Repair and replacement scenarios
Original encoder is discontinued or unavailable. A compatible encoder with a different output interface can be used together with the Encoder Bridge as a direct replacement, without modifying the Fanuc system.
How to Choose Your Version
Your version is defined by two things: your input and your output.
Each SAS IntelliLink Encoder Bridge is a custom-built, fixed-input and fixed-output hardware unit. There is no configuration required on your side. You simply specify the encoder signal you have and the protocol your target system requires — and that determines which device version we build for you.
| You have (input) | You need (output) | Typical use case |
|---|---|---|
| 1 Vpp Sin/Cos | Differential A/B/Z | High-precision encoder feeding a Fanuc-ready interface or standard incremental controller |
| 1 Vpp Sin/Cos | EnDat 2.2 | Retrofitting a legacy encoder to a Siemens or Bosch Rexroth drive with EnDat input |
| Resolver | Differential A/B/Z | Servo motor with resolver driving a CNC system that requires incremental encoder feedback |
| Resolver | EnDat 2.2 | Resolver-equipped motor integrated into a high-accuracy EnDat-based drive chain |
| SSI | CAN (CANopen / J1939) | Absolute encoder feeding position data into a CAN network for machine control or telematics |
| BiSS-C | Differential A/B/Z | Modern BiSS-C encoder adapted to a legacy incremental input on a Fanuc or Mitsubishi CNC |
| TTL / HTL Pulse | CAN (CANopen / J1939) | Incremental encoder integrated into a CAN-based industrial automation or vehicle control network |
| EnDat 2.1 / 2.2 | SSI output | EnDat encoder feeding a PLC or controller that only supports SSI absolute input |

Applications
Where the Encoder Bridge solves real problems.
Encoder signal incompatibility is one of the most common and costly integration problems in industrial automation, CNC and drive retrofit work. The SAS IntelliLink Encoder Bridge eliminates it.
CNC machine retrofits
Upgrading a CNC control to Fanuc while keeping existing encoders. The Encoder Bridge converts legacy signal types to Fanuc Ready differential A/B/Z output — no encoder replacement needed, and each unit is custom-built for the machine.
Servo drive replacement
Replacing a servo drive with a different brand that requires a different encoder protocol. The Encoder Bridge sits between the existing encoder and the new drive — both sides stay unchanged.
Encoder protocol conversion
Machine encoder outputs a protocol (e.g. BiSS-C or EnDat) that the controller or PLC does not natively support. The Encoder Bridge translates to the required interface format.
Drive and motor integration
Integrating third-party motors with resolver or Sin/Cos feedback into drive systems that require digital encoder input. Converts analogue or resolver signals to clean digital output.
CAN network integration
Routing encoder position data into a CAN-based machine network for centralised control, monitoring or telemetry. Converts any encoder signal to CANopen or J1939.
Repair and spare part replacement
Original encoder model is discontinued. A compatible encoder with a different output protocol can be used as a replacement with the Encoder Bridge — no control system changes required.

Encoder Bridge FAQ
Common questions about the SAS IntelliLink Encoder Bridge.
These answers help engineers and buyers confirm whether the Encoder Bridge fits their signal conversion requirement.
Which output protocols are available?
Differential A/B/Z, EnDat 2.2, BiSS-C, CAN (CANopen or J1939) and SSI. Each device version is custom-built for one specific input-output combination.
Is it Fanuc Ready?
Yes. The differential A/B/Z output is Fanuc Ready. This is one of the primary applications of the Encoder Bridge.
How do I select the right version?
Identify your encoder’s output signal type and the protocol your controller or drive requires as input. Those two values define your version. If you’re not sure, send us your encoder and controller datasheets and we will confirm.
Can a Resolver signal be converted to a digital output?
Yes. Resolver is a supported input. It can be converted to differential A/B/Z, EnDat 2.2 or SSI output depending on the custom-built version ordered.
Do you support custom or non-standard signal combinations?
Possibly — contact us with the details of your application. If your combination is not listed, our engineering team will evaluate feasibility and advise.
