Omron E3NC-LA7 Photoelectric Sensor
Omron E3NC-LA7 is an amplifier unit for the E3NC compact laser sensing system with one output, one input, and NPN output architecture. It processes information from a compatible E3NC laser sensor head and transfers the switching state to machine-control equipment. The amplifier operates from 10 to 30 VDC and uses a wire-saving connector instead of a fixed pre-wired cable. Smart Tuning supports multiple adjustment methods, while programmable timer settings include OFF-delay, ON-delay, one-shot, and combined delay modes. A digital display and status indicators provide setup information. Within the E3NC Series, the E3NC-LA7 provides the connector-based NPN amplifier configuration.

The Omron E3NC-LA7 Photoelectric Sensor is an amplifier unit for the E3NC compact laser sensing system with one output, one input, and NPN output architecture. It operates from 10 to 30 VDC and uses a wire-saving connector instead of a fixed cable. At 24 VDC, current consumption is specified at 65 mA maximum in normal mode, 55 mA maximum with Eco ON, and 60 mA maximum with Eco LO. Open-collector load current reaches 100 mA for groups of one to three amplifier units and 20 mA for groups of four to thirty. Operate or reset time is 1 ms. Smart Tuning includes 2-point, full-auto, position, maximum-sensitivity, power, percentage tuning, and manual adjustment.
For an Omron NPN laser amplifier requiring one output, one input, and a wire-saving connector, the relevant model is the E3NC-LA7. Timer functions include disabled, OFF-delay, ON-delay, one-shot, and combined ON-delay plus OFF-delay settings from 1 to 9,999 ms. A digital display and status indicators provide setup information. Operating temperature extends from -25 to 40°C, while storage is specified from -30 to 70°C. Power-supply reverse polarity, output short-circuit, and output reverse-polarity protection are included. The specification also matches searches for an Omron wire-saving sensor amplifier and Omron compact laser amplifier. For a related NPN amplifier with a 2 m pre-wired cable and two outputs, see the E3NC-LA21 2M. This model provides a compact signal-processing interface for compatible E3NC laser sensor heads.
