Guaranteed Safe Checkout
This Heidenhain ECN 1313 is a high-precision absolute rotary encoder designed for demanding motion control applications, particularly common in elevator systems and servo motor feedback. It features a robust design with integrated bearings, a tapered shaft for secure coupling, and the reliable EnDat01 digital interface. This specific package includes a 10-meter pre-terminated connection cable.
Key Features:
- Absolute Positioning: Provides absolute position values immediately upon power-up via the EnDat01 interface (8192 positions/13 bits per revolution).
- Incremental Output: Simultaneously outputs high-resolution incremental signals (~1 Vpp sine/cosine, 2048 lines) for dynamic motion control.
- EnDat01 Interface: Proven synchronous serial interface (EnDat 2.1) for reliable digital data transmission and encoder parameter access.
- Tapered Shaft: Ø 9.25 mm tapered shaft (1:10 taper) ensures a backlash-free, friction-locked connection, ideal for direct motor mounting. Includes M10 and M6 back-off threads for easy disassembly.
- Stator Coupling: Designed with a clamp ring coupling (“Spreizringkupplung”) for Ø 65mm receiving diameter, compensating for mounting tolerances and thermal expansion without dynamic movement (H10 feature).
- Integrated Bearings: Features its own bearings, reducing the load on the motor bearings.
- Robust Construction: Die-cast cover and IP40 protection (when mounted) suitable for industrial environments.
- Wide Operating Range: Supports a supply voltage from 3.6V to 14V DC and a wide operating temperature range (-40°C to +115°C).
- Included Cable: Comes complete with a 10-meter Heidenhain connection cable (P/N on tag: P-K0402-323-0C06), pre-terminated with ferrules/pins for easy integration.
Typical Applications:
This encoder is specifically suited for:
- Elevator Technology (Aufzugsindustrie): Providing precise motor speed and position feedback for smooth ride quality, accurate leveling, and reliable operation in elevator drive systems. Often used with gearless drives.
- Servo Drives: Direct mounting onto servo motors for high-performance position and speed control loops.
- General Automation: Applications requiring accurate absolute positioning and robust digital communication.

Frequently Asked Questions (FAQ) – Heidenhain ECN 1313 2048 62S12-78
Q1: What is the Heidenhain ECN 1313 2048 62S12-78?
It is a high-precision absolute rotary encoder primarily used for measuring angular position and speed in demanding applications like elevator drives and servo motors. It provides both absolute position data (EnDat01) and high-resolution incremental signals (~1 Vpp).
Q2: What does "absolute" encoder mean?
An absolute encoder provides the exact angular position immediately upon power-up, without needing a reference run or "homing" cycle, unlike incremental encoders. This is crucial for applications where losing position after a power cycle is unacceptable, like elevators.
What is the EnDat01 interface, and is it compatible with my system?
EnDat01 is Heidenhain's reliable synchronous serial digital interface for absolute encoders. You must ensure your controller, PLC, or drive system has an input card or interface specifically designed to read EnDat01 signals. Always check the technical documentation of your receiving electronics for compatibility.
Q4: Why is this encoder suitable for elevators and servo drives?
Its robust design, high accuracy, absolute positioning capability (critical for elevators), combined incremental signals for smooth motor control, and the secure tapered shaft mounting make it ideal for the precision and reliability required in modern elevator systems and high-performance servo applications.
Q6: How is this encoder mounted?
It uses a clamp ring stator coupling designed to fit into a Ø 65mm recess or bore on the machine/motor side. A central screw (typically M5x50, included in the mounting kit reference) secures the encoder's tapered shaft onto the mating shaft. Refer to the official Heidenhain Mounting Instructions for detailed procedures.
Q8: What power supply voltage is required?
This encoder supports a wide supply voltage range of 3.6 V to 14 V DC. Ensure your power supply falls within this range and provides stable voltage.
Q10: Can I use this encoder to replace a different model?
Potentially, but careful verification is required. You must ensure the replacement encoder matches the old one in all critical aspects: interface type (EnDat01), resolution (absolute and incremental), shaft type (tapered Ø 9.25mm), mechanical mounting (stator coupling Ø 65mm), supply voltage, and pinout. Consult the datasheets for both encoders or contact Heidenhain/a qualified distributor if unsure. Incorrect replacement can lead to system malfunction or damage.
