| Excellent for sensing even small items where sensing is possible from one side; Recommended for relatively clean environments where high excess gain is not required; Easy-to-operate sensors with few necessary adjustments; Light/Dark Operate select switch and 15-turn Gain potentiometer are protected by a gasketed clear acrylic cover; Multiple sensing modes include: opposed, retroreflective, diffuse, divergent and convergent, plus glass and plastic fiber optic models; Exclusive, patented alignment indicating device system lights a rear panel-mounted LED indicator whenever the sensor sees a light condition; Superimposed pulse rate indicates received light signal strength; Wide array of mounting options; Supply protection circuitry: Protected against transient voltages, DC hookup is without regard to polarity |
