The omron e2s series offers advanced performance and wide range selections in a supercompact size. These sensors come in various models with different sensing distances, output configurations, and operation modes. They are available in both dc 2-wire and dc 3-wire versions, with and without robotics cables, and different frequencies to prevent mutual interference. Sizes range from 5.5 × 5.5 mm to 8 × 8 mm, and sensing distances vary from 1.6 mm to 2.5 mm. Mounting brackets are available separately.
