*NOTES:
i)
9 m (30') cables are available by adding suffix “W/30” to the model number of any cabled sensor (e.g., SM31EL W/30).
ii) A 150 mm (6") long pigtail cable with attached QD connector is available by adding suffix “QDP” to the model number of any
MINI-BEAM sensor (e.g., SM31ELQDP). See page 5 for more information.
iii) A model with a QD connector requires an accessory mating cable. See page 8 for more information.
iv) Emitters and receivers may be ordered with 0.3 millisecond on/off response by adding suffix “MHS” to the model numbers
(e.g., SM31EMHS & SM31RMHS). This modification reduces sensing range (and excess gain).
