Overview
The industry-proven ELF-3 family of hybrid photoelectric sensors offers basic functions for presence detection applications. These low-cost sensors provide a variety of features that can be optimized for customers to reduce installation and procurement costs. They are ideal for standard, short-range applications, such as conveyor systems, vending machines, packaging lines, or other simple on/off applications. ASIC (application-specific integrated circuit) technology, which is proprietary to SICK, guarantees the best optical performance. ELF-3 sensors are available in background suppression, energetic and retro-reflective variants. The background suppression variant offers a 50 mm fixed sensing distance. The energetic variant has a 155 mm sensing range and the retro-reflective variant has a 5 m sensing range. A clear back cover provides highly visible power and status indication. These multi-functional sensors are able to integrate optical and electronic elements into different housings. The ELF-3 comes with integrated M18 threads for front and base mounting.
