New Small Cylindrical Sensors Square Sensor Threaded holes are required in two locations. With Square Sensors: Installation • Time is required to tighten screws. • Mounting brackets are sometimes required. But with Small Cylindrical Sensors: Less Drilling and Tightening Work. Work is reduced because holes do not need to be threaded and there is only one place to tighten. Side-view Sensor Mounted to Horizontal Surface Top-view Sensor Mounted to Vertical Surface Mounting without Brackets. For Through-beam Sensors, both Top-view and Side-view Models are available. Select the shape according to installation...

Small Cylindrical Sensors With Fiber Sensors: Installation • Space is required for the Amplifier. • Setup and installation are troublesome. • Initial and electrical costs are high. But with Small Cylindrical Sensors: Diffuse-reflective Sensors (with Sensitivity Adjuster) Essentially the Same Size as the Fiber Head. But No Amplifier Is Required. Mounting is possible in narrow spaces where only fiber sensors could previously be used. The built-in amplifier and teach-free operation reduce wiring and setup work. And initial costs and electrical costs are also reduced. No Amplifier Less Work Less...
