Panasonic EX-20 Series - Miniature Photoelectric Sensor
All-purpose, ultra-small size photoelectric sensor features high sensing performance
The Panasonic (formerly Sunx) EX-20 Series is one of the world's smallest built-in amplifier sensors, offering both compact size and exceptional performance. With integrated sensitivity adjustment and an impressive sensing range, it is the ultimate all-purpose sensor for installation in even the tightest spaces. EX-20 series features an IP67 rating and is certified as waterproof to be used in process lines where water is used or splashed. Rust-resistant stainless steel sensor mounting brackets are available.
- Miniaturization is achieved by integrating the photodiode and A/D conversion circuit onto a single chip.
- The inverter countermeasure circuit is significantly stronger against inverter light and other extraneous light.
Designed for mounting in tight spaces for all robotic and assembly processes
Side-mounting types are available in diffuse, convergent, retro-reflective, and thrubeam sensing modes.
Ultra-thin types are available in convergent and thrubeam sensing modes.
Side-mounting
Ultra-thin
Advanced miniaturization ensures that, despite its compact size, the EX-20 delivers performance and reliability equal to or exceeding that of conventional models
All side-mount styles features sensitivity potentiometer for fine adjustments. Thru-beams also include ability to select L/O-DO modes
All EX-20 models have metal inserts to prevent tightening damage when securely mounting using M3 screws
The EX-20 series offers long-distance sensing in a miniature package making it ideal for wide conveyor applications with detection ranges of up to 2m. Retroreflective mode provides 200mm distance and includes ultra-compact reflector. 160 mm distance for diffuse reflective sensing.
The narrow-view beam of the EX-28 and convergent type beam of EX-26 provide a red LED light source that emits a precise, focused spot, allowing for easy verification of the sensing position.
Wide Selection of Accessories
Special sensor brackets enable precise beam angle and height adjustments for reflective and thru-beam modes.
A wide range of versatile mounting brackets and beam-reducing slit masks further enhance the EX-20’s sensing performance.
