Block Style Optical Sensors Technical Description When there is no space for traditional sensors, there is only one answer: miniaturization. The diffuse BOS S3 with its small dimensions (13 x 26 x 52 mm) can be used in locations with shallow installation depth (right angle version) or narrow openings (straight version). The series consists of: - Diffuse with 100 mm and 500 mm sensing distance - Thru-Beam with 5 m range, test input and alarm output - Use the diagnostic function to check for proper function - Models with plastic fiber optics permit sensing of miniature objects, checking of individual product markings, and operation in extremely tight locations. BOS S3 Features Applications - Supply voltage 10...30 V DC, reverse polarity protected - Output short circuit protected - Light-On/Dark-On selectable - Sensitivity adjustment with potentiometer - Setup aid and stability display with green LED - IP 66 - Flat window discourages dust accumulation - Can be DIN rail mounted (fiber optic version) - Direct object sensing - Object detection using fiber optics - Parts counting in machine design and conveying, packaging machinery, and assembly lines 2 - Diffuse with focused beam and 12 mm sensing distance, optimal for precise sensing and small parts detection - Retroreflective with polarizing filter for errorless detection of highly light reflecting objects (i.e. packaging with shiny surfaces) 2.73 Block Style Optical Sensors BOS S3 Series Diffuse Retroreflective Thru-Beam Diffuse o/p PNP/NPN*, PNP o/p PNP/NPN*, PNP Diffuse, Fixed Focus PNP/NPN*, PNP o/p Polarized Retroreflective o/p PNP/NPN*, PNP Retroreflective o/p PNP/NPN*, PNP o/p PNP/NPN*, PNP Thru-Beam PNP/NPN*, PNP o/p Slit Apertures Slit width Range Object size 0.5 mm 1 mm 2 mm 0.5 m 1.0 m 2.0 m >0.5 mm >1mm >2mm Reflector R2 Note: Mounting bracket, R2 reflector for retroreflective model, and slit apertures for emitter/receiver are included.

It acts as a warning signal when the function is affected by contamination or mechanical alignment. The alarm output is activated when the receiver signal is in the alarm range for at least 3 seconds. The green stability display illuminates in the "safe" range, where the input energy is at least 30 % over or under the "threshold energy". The "threshold energy" at which a signal change is effected, is defined as 100 %. The "safe" range is therefore reached when: Test Input on Emitter The test input interrupts the light pulses from the emitter and allows the function of the emitter and receiver to be checked (when using Test+, Test- must be at 0 V, when using Test-, Test+ must be at 10...30 V). The receiver output must switch each time when a voltage of 10...30 V DC (Test+) or 0 V (Test-) is present on the test input. Contamination or alignment on the optical axis can cause the emitter signal to reach the receiver only weakly, if at all. Therefore the output will not switch even though the test input is activated. The test function provides a remote check of the thru beam type and serves as a preventative measure. - the input signal is at 130 % or more of the threshold energy. - the input signal is at 70 % or less than the threshold energy.
