Narrow-beam Photoelectric Sensor with Built-in Amplifier E3Z-L CSM E3Z-L DS E 2 3 Small 2.5-mm-diameter Spot Ideal for Detecting Small Workpieces Tiny workpieces as little as 0.1 mm in diameter can be detected with the 2.5-mm-dia. spot. The narrow beam enables sensing from small slots or holes. The small spot of light enables visual checking of sensing spot position. IP67 degree of protection, mutual interference prevention, and EN standard compliance. Be sure to read Safety Precautions on page 4.
