This 40 to 600mm range proximity switch uses pulsed laser light to form a precise beam that can resolve objects down to 0.1mm. An adjustable focus length and sensitivity makes the sensor very versatile. Terminated by an S12 4-pin connector. * Energetic diffuse laser type * Long operating distance * Adjustable focus * High switching frequency * LED for output state and excess light indication * Sensitivity adjustment by means of built-in potentiometer * Short and robust metal housing * Visible red light 660 nm * Glass window
