Omron E3S-DS30E4 Photoelectric Sensor
Omron E3S-DS30E4 is a diffuse-reflective photoelectric sensor designed for sensing transparent and opaque objects across a distance of up to 100 mm. Its 950 nm infrared LED sends light toward the target, while the built-in amplifier processes the returned optical signal. The sensor operates from 12 to 24 VDC and uses a pre-wired cable for electrical integration. Light-ON or Dark-ON operation can be selected according to the required switching logic, while current consumption is specified at 40 mA maximum. Load current is rated up to 80 mA, and response time is specified at 1 ms. Within the E3S Series, the E3S-DS30E4 provides a pre-wired diffuse configuration.

The Omron E3S-DS30E4 Photoelectric Sensor uses diffuse-reflective sensing with a built-in amplifier for transparent and opaque objects across a maximum distance of 100 mm with a 50 × 50 mm white-paper reference. Its 950 nm infrared LED sends light toward the target, while returned light provides the switching information. The sensor operates from 12 to 24 VDC and uses a pre-wired cable for electrical connection. Current consumption is specified at 40 mA maximum, while output current is listed from 1.5 to 4 mA and load current reaches 80 mA maximum. Light-ON or Dark-ON operation can be selected, while a sensitivity adjustment indicator supports setup. Operate or reset time is specified at 1 ms maximum.
For an Omron pre wired diffuse photoelectric sensor requiring 100 mm sensing and a 950 nm infrared source, the relevant model is the E3S-DS30E4. Ambient-light resistance reaches 3,000 lx under incandescent light and 10,000 lx under sunlight. Operating temperature extends from -25 to 55°C and storage from -40 to 70°C. Zinc die-cast, polycarbonate, and iron are among the listed materials. Its specification also suits searches for an Omron 100 mm diffuse sensor and Omron 1 ms photoelectric sensor. For another E3S DS30 configuration with the same stated 100 mm working range, see E3S-DS30E41.
