Omron E3NC-SA21 2M Smart Laser Photoelectric Sensor
Omron E3NC-SA21 2M is an amplifier unit for the E3NC compact laser sensing system with two outputs, one input, and NPN output architecture. It processes signals from a compatible laser sensor head and transfers the resulting switching information to machine-control circuitry. The amplifier operates from 10 to 30 VDC and includes a 2 m pre-wired cable for electrical integration. Light-ON or Dark-ON operation can be selected, while the listed response time is 1.5 ms maximum. Timer settings include OFF-delay, ON-delay, one-shot, and combined ON-delay plus OFF-delay modes. Within the E3NC Series, the E3NC-SA21 2M provides the pre-wired NPN amplifier configuration. Related NPN laser sensor amplifiers are available across Omron Automation Sensors.

The Omron E3NC-SA21 2M Photoelectric Sensor is an amplifier unit for the E3NC compact laser sensing system with two outputs, one input, and NPN output architecture. It operates from 10 to 30 VDC and includes a 2 m pre-wired cable for electrical connection. Power consumption is specified at 1,920 mW maximum. Light-ON or Dark-ON operation can be selected according to the required switching logic, while response time is listed at 1.5 ms maximum. Timer functions include disabled, OFF-delay, ON-delay, one-shot, and combined ON-delay plus OFF-delay settings from 1 to 9,999 ms. The main digital display is white and the sub display is green, supported by OUT, L/D, ST, DPC, and output-selection indicators. Output short-circuit protection is also listed.
For an Omron NPN laser sensor amplifier requiring two outputs, one input, and pre-wired connection, the relevant model is the E3NC-SA21. Operating temperature extends from -25 to 55°C, with storage from -30 to 70°C. Humidity is specified at 35% to 85%, while insulation resistance is 20 MΩ at 500 VDC. Dielectric strength is listed at 1,000 VAC for one minute. Case and cover materials are polycarbonate, while the cable uses PVC. Its specification also matches searches for an Omron two output sensor amplifier and Omron 1.5 ms laser amplifier. This unit provides signal processing between a compatible sensing head and machine-control circuitry. For a related E3NC amplifier using an M8 connector with one NPN output, see E3NC-SA24.
