Autonics ENC Series ENC-1-1T-24 Wheel Roller E58S6-1000 Rotary Incremental Encoder E30S4 E40S E40H E50S8 E50S8 E58SC E60H E68S E80H E100H ENA ENC ENH ENHP EP50S Absolute Encoder

Key Features and Performance

Autonics ENC rotary encoder series addresses two distinct performance tiers through the E40S and E58S models. The E40S packs high-speed 300kHz frequency response into a compact 40mm diameter housing, enabling accurate measurement at high rotational speeds where slower encoders produce signal errors. This response speed suits applications like spindle speed feedback on CNC machines and high-speed packaging equipment.

The E58S delivers 2048 pulses per revolution with sine wave output for applications demanding fine angular resolution and smooth interpolation. Sine/cosine output enables downstream electronics to interpolate between pulses, achieving effective resolutions far beyond the base 2048 P/R — critical for precision positioning in Malaysian semiconductor and electronics manufacturing.

Both models feature the ENC wheel mounting system that simplifies installation on shafts where direct coupling is impractical. The spring-loaded wheel maintains consistent contact with rotating surfaces, converting linear or rotational motion into accurate pulse output without rigid mechanical coupling.

Robust shaft sealing protects optical components from dust and moisture ingress — essential for Malaysian factory environments where airborne particles and humidity challenge encoder reliability. Ball bearing shaft supports handle radial and axial loads from belt-driven and direct-coupled installations.

Output options include NPN open collector, PNP open collector, line driver (differential), and voltage output, matching the input requirements of PLCs, counters, and motion controllers used across Malaysian automation systems. Complementary (A/B/Z) channel output provides directional sensing for position tracking applications.

Technical Specifications

Applications in Malaysian Industry

Autonics ENC rotary encoders operate across Malaysian manufacturing where accurate motion feedback enables process control and quality assurance. CNC machine shops in the Klang Valley and Penang use E40S encoders for spindle speed monitoring and axis position feedback. Packaging machinery manufacturers integrate E40S for registration mark synchronisation on high-speed wrapping and labelling lines.

E58S sine encoders serve Malaysian servo drive applications requiring smooth velocity feedback for vibration-free motion. Semiconductor wafer handling equipment in Penang uses E58S for sub-degree positioning accuracy. Printing press manufacturers deploy E58S for colour registration control. These precision applications align with NIMP 2030 goals of elevating Malaysian manufacturing into high-value, technology-intensive production.

Autonics ENC vs Alternatives

Autonics ENC encoders deliver specifications comparable to Omron E6C/E6F and Sick DFS60 series at a lower price point, supported by regional availability through Flextech Industrial. The E40S 300kHz response matches or exceeds compact encoders in its size class. E58S sine output quality enables interpolation factors rivalling dedicated servo-grade encoders. For applications requiring absolute position (multi-turn), Autonics offers complementary absolute encoder models.

Frequently Asked Questions

What is the difference between Autonics E40S and E58S encoders?

E40S is a compact 40mm incremental encoder optimised for high-speed applications with 300kHz frequency response and digital pulse output. E58S is a 58mm encoder providing sine/cosine analog output at 2048 P/R for precision positioning applications requiring interpolation.

Can Autonics encoders connect to any PLC brand?

Autonics ENC encoders offer multiple output types — NPN, PNP, line driver, and voltage — compatible with all major PLC brands used in Malaysia including Mitsubishi, Siemens, Omron, and Allen-Bradley. Select the output type matching your PLC’s high-speed counter input specification.

What resolution is available for the E40S encoder?

E40S encoders are available in resolutions up to 2500 pulses per revolution. With quadrature decoding (x4) on the receiving counter, effective resolution reaches 10,000 counts per revolution — sufficient for most speed and position measurement applications in Malaysian automation.

How do I mount an Autonics ENC wheel encoder?

ENC wheel encoders mount using a spring-loaded arm that presses the measurement wheel against the moving surface. The spring mechanism maintains consistent contact force, ensuring reliable pulse generation without rigid shaft coupling. This mounting method suits retrofit installations on existing Malaysian equipment.
