mini-beam sensors sm2a312cv and sm2a312cv2 page 2 mini-beam installation and alignment proper operation of the sm2a312cv or sm2a312cv2 sensor requires that 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 cir cuit and with the sensor set for ?ight operate? direct the sensor s visible red spot at the object 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 ver y slightly toward or away from the object while obser ving 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. 15 t urn gain adjustment and light/dark operate switch* gasketed acr ylic cover red led lights when the sensor's output is conducting lo w reflectivity bac kgr ound up do wn left right sm2a312cv or sm2a312cv2 object * note regarding light/dark operate switch: ?t urn switch fully clockwise for light operate (sensor outputs conduct when object is present) ?t urn switch fully counter clockwise for dark operate (sensor outputs conduct when object is absent) distance from sensor lens to object: 16 mm (0.65 in) for sm2a312cv 43 mm (1.7 in) for sm2a312cv2 convergent mode alignment sm2a312cv or cv2
