SICK 1084229 (EKS36-0KF0B018A) is a compact rotary motor feedback system designed for precise absolute position feedback in servo and drive applications. Using an optical measuring principle and HIPERFACE DSL communication, it provides high-resolution single-turn position information with 18-bit resolution (262,144 steps per revolution) and a system accuracy of ±120 arcseconds, supporting stable closed-loop control for demanding motion tasks.
Built for integration on motors, this EKS/EKM36 series unit features a tapered shaft design with stator coupling and supports operating speeds up to 12,000 rpm. It operates from a 7–12 V supply (recommended 8 V) with low power consumption (≤150 mA) and uses a 4-pin male connector interface for combined supply and communication. The encoder is suitable for industrial environments with an operating temperature range of –20 °C to +115 °C and IP40 enclosure rating when fitted with the matching connector and closed cover.

What is this device used for in a drive system?
It is a rotary motor feedback device that provides absolute position information to a compatible drive/controller via the HIPERFACE DSL interface, helping the system determine rotor position for commutation and precise motion control.
Which communication interface does it use?
It uses HIPERFACE DSL, combining power and bidirectional communication over a simple connection to a compatible drive system.
Is the position output absolute or incremental?
The position is absolute within one mechanically ascertainable revolution (single-turn absolute), so the absolute position within that revolution is known after initialisation.
What resolution does it provide per revolution?
The resolution is 18-bit per revolution, which corresponds to 262,144 measurement steps per revolution.
What accuracy can I expect from the position measurement?
Typical system accuracy is specified as ±120 arcseconds, with signal noise (1σ) specified as ±5 arcseconds under the stated conditions.
What supply voltage range is required?
It operates from 7 V to 12 V DC, with a recommended supply voltage of 8 V.
How much current does it typically draw?
Power consumption is specified as up to 150 mA (when used with the recommended interface circuit approach for HIPERFACE DSL installations).
What connector and pinout does it use?
It uses a 4-pin male connector. Pin 1 is not connected, Pin 2 is +US/DSL+, Pin 3 is GND/DSL-, and Pin 4 is housing/screen connection.
Does it include temperature sensing for the motor?
Yes. It supports transmission of an external temperature resistor measurement (32-bit value without prefix), covering 0 to 209,600 Ω, intended for use with typical NTC/PTC sensor elements.
What mechanical shaft style is used?
It is specified with a tapered shaft version and is designed for use with a stator coupling arrangement.
What maximum speed can it run at?
The permissible operating speed is up to 12,000 min⁻¹ (rpm).
What are the permissible shaft movement tolerances during operation?
Permissible movement of the drive element is specified as ±0.1 mm radial and ±0.5 mm axial (static), and ±0.05 mm radial and ±0.1 mm axial (dynamic).
What environmental conditions is it rated for?
Operating temperature range is -20 °C to +115 °C (with appropriate thermal coupling), storage temperature range is -40 °C to +125 °C, and relative humidity up to 90% with no condensation.
What ingress protection rating does it have?
The enclosure rating is IP40 when the mating connector is inserted and the cover is closed.
How quickly is it ready after power is applied?
Initialisation time is specified as a maximum of 500 ms after reaching a permitted operating voltage (with a warm-up time during the voltage ramp specified up to 180 ms).
What is the approximate weight of the unit?
The specified weight is approximately 0.1 kg.
Are there any common installation considerations for reliable signal performance?
For best results, use appropriate screening/earthing practices for the housing and cable screen, ensure the mating connector is properly seated (to maintain IP40), and keep within the specified shaft movement and speed limits. For reference, this configuration corresponds to SICK item 1084229.
