Note: Models numbers for Through-beam Sensors (E3S-[]E4, E3S-[]E41) are for sets that include both the Emitter and
          Receiver.
          The model number of the Emitter is expressed by adding "L" to the set model number (example: E3S-2LE4), the
          model number of the Receiver, by adding "D" (example: E3S-2DE4.) Refer to Ordering Information to confirm model
          numbers for Emitter and Receivers.

Slit (Order Separately)
E39-S2

E3S Dimensions 22

Note 1. Three sets of slits are provided: 6.5 x 0.5 mm, 6.5 x 1 mm and 6.5 x 2 mm
         2. One set consists of two slits, one each for the Emitter and Receiver.

E39-S1

E3S Dimensions 23

Note 1. Four sets of slits are provided: 11 x 0.5 mm, 11 x 1 mm, 11 x 2 mm, and 11 x 4 mm
          2. One set consists of two slits, one each for the Emitter and Receiver.
Note: The dimensions in parentheses are for when the Spacer is not used.
* With the E3S-2E4 (41), use the Spacer as shown in the figure above so that the supporter and Mounting Bracket will not
   be struck when the optical axis is adjusted.
   With the E3S-5E4 (41), the Spacer is not particularly required. Use the Spacer, however, to directly mount both the E3S-
   2E4 (41) and -5E4 (41).
