See page 5 for more information. iii) A model with a QD connector requires an accessory mating cable. See page 5 for more information. Printed in USA P/N 03402L7H MINI-BEAM Sensors SM2A312CV and SM2A312CV2 MINI-BEAM Installation and Alignment Proper operation of the SM2A312CV or SM2A312CV2 sensor requires that CONVERGENT MODE ALIGNMENT it be mounted securely and aligned properly. In some applications, excessive movement or vibration can result in intermittent or false operation caused by loss of alignment. For best results, final-mount the sensor in an 18mm-hole by its threaded barrel or use a mounting bracket (see page 6). Begin with the sensor at the approximate position where it will be mounted. With power applied to the circuit and with the sensor set for SM2A312CV light operate, direct the sensors visible red spot at the object or SM2A312CV2 approximately 16 mm (0.65 in) (for model SM2A312CV) or 43 mm (1.7 in) (for model SM2A312CV2) directly in front of the lens. Move the sensor very slightly toward or away from the object while observing the red LED indicator on the back of the sensor. Note the near and far points at which sensing occurs (the range of distance over which the LED remains lit). Mount the sensor at a point approximately midway in the range. This should correspond to the point at which the red sensing spot on the object appears most sharply defined. Mount the sensor at this position and distance. Distance from Sensor lens to object: 16 mm (0.65 in) for SM2A312CV 43 mm (1.7 in) for SM2A312CV2 SM2A312CV OR CV2 15 Turn Gain Adjustment and Light/Dark Operate Switch* Gasketed Acrylic Cover Red LED lights when the sensor s output is conducting * Note regarding Light/Dark operate switch: Turn switch fully clockwise for light operate (sensor outputs conduct when object is present) Turn switch fully counterclockwise for dark operate (sensor outputs conduct when object is absent) page 2 Low Reflectivity Background Object Up Left Right Down
