Autonics introduced a new ultra-compact, ultra-thin photoelectric sensor with a thickness of 7.2mm, suitable for installation in tight spaces. BTS series can detect 0.15mm* metal wires, semiconductor chips and other fine objects. The BTS series is IP67 rated and equipped with stainless steel mounting brackets for long-lasting, reliable performance in a variety of environments. Limited distance reflective type main feature Only 7.2mm thick - W7.2 x H18.6 x L9.5mm (for shooting type) - W7.2 x H24.6 x L10.8mm (specular, limited distance reflective) Detection method and minimum detection size - On-beam type (BTS1M): ?2mm - Specular reflection type (BTS200): ?2mm (detection distance 100mm) - Limited Range Reflection Type (BTS15/BTS30): ?0.15mm (detection distance 10mm) Detection distance may vary due to environmental factors Stability indicator (green LED) and action indicator (red LED) Stainless steel (SUS304) mounting bracket IP67 protection level (IEC standard) Home Energy Storage,Bicycle Lithium Battery,Electric Bicycle Battery,Electric Bicycle Lithium Battery Pack Sichuan Liwang New Energy Technology Co. , https://www.liwangnewenergy.com
