Photoelectric sensors operate in tight spaces
Pepperl+Fuchs introduced R2 Series Ultra-Small Sensors - a complete family of ultra-miniature photoelectric sensors available in four sensing modes to suit varied application needs. These sensors feature a 24 mm x 7.5 mm x 11.2 mm housing, industry standard mounting footprint, a flush and wear-resistant antistatic glass lens and a 45-degree cable outlet to maximize mounting flexibility. Consequently, the R2 series can be mounted where other photoelectric sensors cannot – in extremely tight spaces and close to moving objects – to deliver high performance and reliable operation in a wide range of applications regardless of the color, texture or shape of the object(s) being sensed. Industry standard 15 mm mounting hole separation enables R2 Series sensors to easily retrofit into existing applications. Threaded sensor mounting holes enable installation without mounting nuts to simplify installation and save time. This also negates the potential to lose or drop mounting nuts while installing a sensor in very small, tight spaces. These sensors feature a glass optical surface which is more resistant to environmental contaminants, chemicals and abrasion than is the fragile plastic optical surface of many conventional photoelectric sensors. Additionally, the tamperproof housing of each R2 series sensor ensures that unauthorized personnel cannot make modifications or alterations after the sensor is setup. Enhanced and strategically placed LEDs clearly indicate the sensor’s operating state.
