The Omron E4PA-LS200-M1-N, also cataloged as the E4PA-LS200 Ultrasonic Displacement Sensor, operates as a dedicated hardware component for non-contact distance measurement and linear position tracking within automated sensing loops.

Model Coding Structure

• E4PA: Ultrasonic displacement sensor series designation.
• LS200: Sensing range specification covering 120 to 2,000 mm.
• M1: Standard M12 connector connection interface.
• N: Updated hardware revision code with mutual interference protection logic.

Technical & Operating Parameters

Deterministic Network Bus & Module Interfacing

The internal analog processing subsystem maintains direct signal integrity when feeding continuous 4-20 mA loops into PLC expansion modules, supporting expanded I/O density scaling across system architectures. Internal memory parameters and calibration routines preserve ongoing firmware flash compatibility across Sysmac configuration tools.

Physical Alignment & Wiring Execution

Mechanical Mount Configuration

Fix the sensor housing securely using the provided mounting hardware. Angle the sensor face perpendicular to the target surface (100 x 100 mm flat plate benchmark) to ensure maximum acoustic signal reflection.

Cable Connections & Shielding

Route 4-wire shielded M12 cable assemblies away from heavy motor leads. Connect the analog loop directly to PLC analog input cards, ensuring allowable load limits (500 Ohm for current, 1,000 Ohm for voltage) are respected.

Alignment Clearance & Blind Zones

Ensure no object enters the 0 to 120 mm dead band zone in front of the transducer face. Maintain lateral spatial clearances to avoid acoustic beam reflection off adjacent machine framing.
