EPS: Next-Generation Electronic Limit Switches from RACO

These state-of-the-art devices are designed to deliver greater precision, flexibility, and reliability in motion control applications—making them a modern replacement for traditional mechanical limit switches.

Smarter Position Tracking

Both the EPS02 and EPS06 utilize non-contact magnetic sensing to monitor shaft or motor rotation. This movement is converted into 256 digital pulses per revolution, allowing for high-resolution tracking of position. These pulses are then processed and saved to non-volatile memory, meaning even a complete power loss won’t erase the absolute position of the system—a critical advantage for automation and safety.

EPS02: Compact, Configurable, and Capable

The EPS02 is the base model, offering essential features with maximum reliability. It includes:

• 2 adjustable end positions (relay contacts)

• Relay output contacts (250VAC, 5A) for robust electrical interfacing

• Digital resolution < 0.01 mm

• An RS232 serial interface for quick setup and configuration

• Battery buffering in the case of a power failure (service life > 10 years)

Ideal for applications that require accurate and repeatable motion limits, the EPS02 brings the benefits of digital control into a compact form factor.

EPS06: Enhanced Functionality for Demanding Applications

Building on the foundation of the EPS02, the EPS06 adds advanced capabilities through an expansion board connected via ribbon cable. This upgrade introduces:

• Scalable analog outputs (4–20mA or 0–10VDC)

• Pulse Width Modulation (PWM) output signals

• 2 end positions (relay contacts) and 4 adjustable intermediate positions (24 VDC NPN transistor outputs)

• RPM function - adjustable thrust overload shutdown

• A convenient USB interface port for configuration and diagnostics

The EPS06 is perfect for more complex applications where versatility and real-time feedback are essential.

Seamless Integration

Both EPS models are direct replacements for RACO's legacy mechanical limit switches and can be easily installed using the same accessory housings. This means upgrading to digital precision doesn’t require a complete system overhaul.

Easy Setup with RACO Software

For system setup, configuration, and parameter management, users can take advantage of the RACO Setup PC Tool. Full installation and interface instructions are available in the EPS software manual.
