EKA supplies Siemens encoders for industrial machinery, providing accurate feedback for motor, spindle, and axis applications. These encoders act as direct measuring systems, detecting position, speed, rotation angle, and travel distance for reliable machine control.We confirm the right model by checking the MLFB, required signal/interface, connectors, and mechanical fit, helping prevent mismatch and downtime.

Delivery: Pan-India (Chennai, Bengaluru, Pune, Mumbai, Ahmedabad, Hyderabad, Delhi)

Types of Siemens Encoders

Incremental Encoders

Incremental encoders output signals that the control system counts to calculate motion. Common Siemens incremental encoder signal families include TTL/RS422, HTL, and Sin/Cos (1 Vpp) depending on the model.

Absolute Encoders

Absolute encoders provide a position value that the system can interpret directly (based on configuration). Siemens offers absolute encoder families across multiple industrial interfaces including DRIVE-CLiQ, SSI, EnDat 2.1, PROFIBUS DP, and PROFINET IO.

Linear / Rotary Encoders (motion type)

  • Rotary encoders measure rotation (motor shafts, spindles, shafts).
  • Linear encoders measure travel along an axis (machine tools, gantry motion, precision slides).

SIEMENS ENCODERS

Incremental Encoder

Incremental-Encoders

Incremental encoders provide relative feedback by generating signals as the shaft turns. Your drive/CNC/PLC uses these signals to calculate speed, direction, and movement. Siemens incremental encoders are typically selected by output signal standard—so the correct choice depends on what your controller input supports.

Sin/Cos 1 Vpp Incremental Encoder (10360752)

These encoders output analog sine and cosine signals (1 Vpp). They are commonly chosen where smoother feedback and higher signal quality are preferred—especially in precision applications and many servo/axis setups.
Use this type when: your drive feedback input specifically supports 1 Vpp sin/cos.
Before supply, we confirm: interface match (1 Vpp), connector/cable type, and mechanical mounting (shaft/bore, flange, coupling).

RS422 (TTL) Incremental Encoder (10360753)

RS422 (TTL) encoders provide digital square-wave signals using a differential format that helps with noise immunity in industrial environments. This is a common choice for CNC and drive systems that require TTL/RS422 feedback.
Use this type when: your system input requires TTL/RS422 (not HTL).
Before supply, we confirm: required resolution/pulses, signal type (TTL), connector/cable, and mounting fit.

HTL (10–30 V) Incremental Encoder (10360754)

HTL encoders provide high-voltage digital signals, commonly used in 24 V industrial control panels and PLC high-speed counter applications. They are often preferred where stronger signal levels and simpler industrial wiring practices are used.
Use this type when: your PLC/counter expects HTL (10–30 V) signals.
Before supply, we confirm: your input type is HTL (not TTL), supply availability, cable/connector, and mechanical fit.

Absolute Encoder

Absolute encoders provide position data as a coded value, so the system reads position directly (instead of calculating only by counting pulses). Siemens absolute encoder ranges are commonly selected by the interface your drive/PLC/CNC supports

Absolute encoders with DRIVE-CLiQ

Recommended for Siemens drive systems that use the DRIVE-CLiQ ecosystem. Digital feedback, simplified integration (when your system is designed for DRIVE-CLiQ).
Best for: SINAMICS-based setups and Siemens motion systems using DRIVE-CLiQ devices.

Absolute encoders with SSI

SSI is a common serial interface used with many PLC/drive encoder inputs and interface modules.
Best for: systems that explicitly specify SSI in the encoder input spec.

Absolute encoders with EnDat 2.1

EnDat is used where higher-resolution serial feedback is required (model/system dependent).
Best for: applications that require EnDat 2.1 feedback at the drive/feedback module.

Absolute encoders with PROFIBUS DP

These models are chosen when the encoder must communicate over PROFIBUS DP, acting as a network device rather than a simple pulse/serial signal source.

Absolute encoders with PROFINET IO

Selected when your system requires encoder feedback over PROFINET IO (Ethernet-based).
Best for: PROFINET IO automation architectures where position data is read via Industrial Ethernet.

FAQ – Siemens Encoders

Which Siemens encoder do I need: Incremental or Absolute?

Choose incremental when your system counts pulses for speed/position (relative feedback). Choose absolute when your system needs a unique position value via a supported interface (e.g., DRIVE-CLiQ / SSI / EnDat / PROFINET / PROFIBUS).

What’s the difference between 1 Vpp vs TTL (RS422) vs HTL encoders?

  • 1 Vpp = analog sine/cosine signals (often used where interpolation/high-quality feedback is needed).
  • TTL (RS422) = digital differential square-wave signals.
  • HTL = higher-voltage digital signals typically used with 24 V level inputs (model/system dependent). 

How do I know if my system needs HTL or TTL?

Check your PLC/drive encoder input spec: TTL/RS422 inputs are not the same as HTL (10–30 V) inputs. If the input expects 24 V-level signals, HTL is usually the correct family; if it expects RS422/TTL, choose TTL.

What is DRIVE-CLiQ and when do I need a DRIVE-CLiQ encoder?

DRIVE-CLiQ is Siemens’ digital interface used to connect motors/encoders in certain Siemens drive systems. Many Siemens platforms provide 24 V DC supply for encoders/measuring systems via DRIVE-CLiQ (450 mA per interface) (device dependent).

Do you supply DRIVE-CLiQ encoder cables (M12)?

Yes—Siemens also documents MOTION-CONNECT DRIVE-CLiQ signal cables with M12 connection system up to 100 m (application dependent). Share your encoder and drive details so we match the correct cable/connector.

SSI vs EnDat 2.1 — which absolute encoder interface should I choose?

Use the interface your drive/module supports: SSI is a common serial interface; EnDat 2.1 is a bidirectional interface used with certain feedback modules/drives. If your system is already EnDat-based, stay EnDat; don’t substitute SSI (or vice versa) without confirming compatibility.

Is EnDat 2.2 compatible with EnDat 2.1 (Siemens drives)?

Siemens notes EnDat 2.2 is supplied as a compatible replacement for EnDat 2.1 in many cases, but compatibility depends on the drive/feature support and the encoder variant selected. Always confirm with your drive type and application.

How do I identify the correct Siemens encoder MLFB / part number?

Best method: send a clear photo of the encoder label and the motor nameplate. Siemens technical data and documentation are typically referenced by MLFB/Order number, which is what we use to match the exact variant.

Can I replace an obsolete Siemens encoder with an alternative?

Often yes—but only after matching: interface/output (DRIVE-CLiQ/SSI/EnDat/TTL/HTL/1Vpp), supply voltage, connector, and mechanical fit. Share the old label + drive model so we can propose the correct replacement path.

What does Siemens fault F31120 “encoder power supply fault” mean?

Siemens describes F31120 as an encoder power supply fault being detected (model/system dependent). First checks are typically: power supply health, cable/connector condition, and correct wiring/cable type for the encoder interface.

What is zero mark distance error (often seen as A31400 / similar)?

Siemens notes the zero mark monitoring distance is set via parameters like p0425 (rotary encoder) or p0424 (linear encoder) (system dependent). If your system alarms here, it often points to mismatch in encoder type/settings, signal quality issues, or incorrect parameterization.

Do you supply PROFINET IO or PROFIBUS DP absolute encoders?

Yes—Siemens absolute encoders exist with interfaces like PROFINET IO and PROFIBUS DP-V2 (model dependent). Share your network requirement and MLFB/label photo to match the correct unit.

What details should I send for the fastest quote / correct match?

Send these 4 items:
Encoder label/MLFB photo
Motor nameplate photo
Drive/PLC model
Required interface/output (1Vpp / TTL-RS422 / HTL / DRIVE-CLiQ / SSI / EnDat / PROFINET / PROFIBUS)
