The Omron E3NC-LA21 2M Photoelectric Sensor operates with a power supply voltage of 10 to 30 VDC, incorporating reverse polarity protection to ensure safe integration. This model uses an NPN output configuration and comes pre-wired with a durable 2-meter cable, suitable for fast, secure installation. Its smart tuning features—including 2-point, full auto, and percentage tuning—allow for adaptive sensitivity adjustments based on diverse object types and distances.

Designed for real-time responsiveness, the sensor boasts a 1 ms response time, while power consumption modes like Eco ON and Eco LO help reduce energy draw to as low as 1,320 mW. The device includes advanced timer functions ranging from 1 to 9,999 ms and features a multi-color digital display for clear feedback. Its robust build ensures shock resistance up to 500 m/s², vibration tolerance from 10 to 55 Hz, and reliable performance across a wide ambient range of −25 to 40°C.

With protection circuits for overcurrent and polarity errors, and high insulation resistance of 20 MΩ at 500 VDC, this laser sensor offers industrial-grade durability in a lightweight (approx. 115 g) polycarbonate housing. Trusted across machine vision, part detection, and edge positioning applications, the E3NC-LA21 2M stands as a smart investment for engineers requiring precision and reliability.
