Small light curtain
|
The SF2-A series of sensors utilize the latest advances in SUNX sensor technology to provide a variety of useful functions while meeting international standards. At 28mm wide and 19mm thick, it can be installed in small spaces within equipment. Unaligned beam axes can be seen at a glance. Sensors are available with beam pitches of 20mm and 40mm, and the protective height for sensors ranges from 190mm to 1950mm. The ELCA (Extraneous Light Check & Avoid) function enhances the mutual interference prevention function. This function recognizes extraneous light and prevent malfunctions.
NPN - PNP output types are also available for all models. Characteristics: - High level of safety achieved
- Space-saving design, only 28mm wide and 19mm thick
- Wide product range
- Unaligned beam axes can be seen at a glance
- Mutual interference prevention (ELCA)
- NPN/PNP types available
Options:
- Mating cables (3, 7, 10m)
- Slit mask
- Front protection cover
- Mounting brackets
- Safety relay unit
- Laser alignment tool
