Miniature optical sensor

February 2004 Sensors & Transducers

Omron's E3T from Yelland Control, is a compact photoelectric sensor series and is available as a through-beam, retro-reflective and scanning type with background suppression. It features integrated optics and electronics, and is ideal for detecting tiny components such as ICs.

Polarity protection and a short-circuit-proof switch output are integrated, as are the function display and stability display. Its small dimensions make the E3T ideal for applications where space is limited and ambient requirements are demanding.

Omron's pin-point LED produces a high-output narrow-visibility beam of 0,8 mm spot diameter (E3TSL1). A red spot can be seen clearly and optical axis alignment and detection position checks are easy. The LED is not affected by the colour of the item or the background, and can detect even small items with accuracy.

PDS implementation on mines
Sensors & Transducers
Level 9 vehicle intervention for collision avoidance has been mandatory on South African mines since 2022, yet the effective roll-out of proximity detection systems remains slower than expected. This is not due to the technical limitations of integration but to operational readiness on site.
