WARNING: Not To Be Used for Personnel Protection

Never use this device as a sensing device for personnel

protection. Doing so could lead to serious injury or

death. This device does not include the self-checking

redundant circuitry necessary to allow its use in

personnel safety applications. A sensor failure or

malfunction can cause either an energized or de-

energized sensor output condition.

MINI-BEAM® AC Voltage Series Opposed Mode Alignment “Flooding” occurs when a portion of the sensing beam passes around the object to be sensed. “Burn-through” occurs when a portion of the emitter’s light energy passes through a thin or translucent object, and is sensed by the receiver.

MINI-BEAM® AC Voltage Series Convergent Mode Alignment The sensing energy of a convergent mode sensor is concentrated at the specified focus point. Convergent mode sensors are less sensitive to background reflections, compared with diffuse mode sensors.
