Remove the target and confirm that the operation indicator is OFF and the stability indicator (green) is ON. - Note: For Light-ON, adjustment is similar, except that indicators would operate in opposite manner as with Dark-ON. 11 ~~rr~~ **E3T** ~~ONTODr~~ **E3T** Unit: mm (inch) 7 **MOUNTING BRACKETS** **==> picture [372 x 236] intentionally omitted <==** **----- Start of picture text -----**<br> E39-L116 (use with E3T-S OOO ) Order Separately<br>Two, R1.7<br>17.8<br>(0.70)<br>— Two, R2<br>Two, R2<br>_ 10.3<br>(0.41)<br>TA i 9.7 cr.<br>Material: 1.2-mm-thick<br>stainless steel (SS 304) (1.23)31.2 Two, R1.1 (0.38)<br>1 (0.70)17.8<br>Two, R1.2<br>R1.5 max.<br>10<br>(0.39)<br>**----- End of picture text -----**<br> ## **E39-L116 (use with E3T-ST1** O **)** **==> picture [225 x 89] intentionally omitted <==** **----- Start of picture text -----**<br> Four, R2 Two, M2 × 12<br>Three, M2<br>20.5<br>(0.81) 31<br>(1.22) 31.2<br>(1.23)<br>24.5<br>(0.96)<br>7<br>(0.28)<br>**----- End of picture text -----**<br> 12 **E3T** **E3T** Order brackets separately. **E39-L117 (use with E3T-S** OOO **)** **==> picture [293 x 178] intentionally omitted <==** **----- Start of picture text -----**<br> R1 max.<br>de. +<br>Two, R1.7 Two, R2 Two, R2<br>11.2——/<br>Se ‘of W<br>Material: 1.2-mm-thick<br>stainless steel (SS 304)<br>18<br>(0.71) 23<br>(0.91)<br>i° 5 15 | pe<br>O Cinsins<br>3.4 aa Two, R1.7 sto LN 222<br>(0.13)<br>4.5<br>(0.18) Two, R1.1<br>11.2<br>(0.44)<br>**----- End of picture text -----**<br> > **E39-L117 (shown with E3T-ST1** O **)** **==> picture [258 x 62] intentionally omitted <==** **----- Start of picture text -----**<br> Two, M2 × 12<br>10.2<br>Four, R2 Three, M2 (0.40) 11.2<br>(0.44)<br>= A<br>20.5<br>(0.80) 1s if ileilae 23 ee<br>| | | u Up (0.91) a<br>**----- End of picture text -----**<br> 13 **E3T** **E3T** ## Unit: mm (inch) Order brackets separately. > **E39-L118 (use with E3T-S** OOO **)** **==> picture [273 x 180] intentionally omitted <==** **----- Start of picture text -----**<br> 11.5<br>(0.45)<br>11.5<br>(0.45)<br>bi eo 22.7 (0.89)<br>Two, R1.7<br>Material: 1.2-mm-thick<br>stainless steel (SS 304)<br>15 5<br>(0.59) (0.20) 23<br>(0.91)<br>Cam D,<br>Two, R1.1 Four, R2<br>**----- End of picture text -----**<br> ## **E39-L118 (shown with E3T-ST1** O **)** **==> picture [320 x 87] intentionally omitted <==** **----- Start of picture text -----**<br> 13.2<br>Four, R2 Three, M2 Two, M2 × 12 (0.52)<br>20.5<br>(0.81) oe 15 felt e | 0 23<br>= (0.59) Hilf [QJ (0.91)<br>**----- End of picture text -----**<br> 14 **E3T** **E3T** ## **Mounting Brackets for E3T-FT1** Oo **/E3T-FD1** Oo **N** **E39-L119** ## **E39-L119 shown with E3T-F** og **1** **==> picture [16 x 13] intentionally omitted <==** **----- Start of picture text -----**<br> 10.5<br>(0.41)<br>**----- End of picture text -----**<br> **==> picture [133 x 82] intentionally omitted <==** **----- Start of picture text -----**<br> Four, M2 tapping holes<br>16 cet<br>(0.63) 12<br>(0.47)<br>< £<br>k (0.35)9 4 (0.28)7<br>**----- End of picture text -----**<br> **==> picture [76 x 38] intentionally omitted <==** **----- Start of picture text -----**<br> 10.6<br>(0.42)<br>+ 2 8<br>a Two, M2 × 4<br>**----- End of picture text -----**<br> ## **E39-L120** ## **E39-L120 shown with E3T-F** og **1** **==> picture [133 x 100] intentionally omitted <==** **----- Start of picture text -----**<br> 22.5 (0.89)<br>Four, M2 tapping holes<br>3.2<br>t = (0.09)2.4<br>oS A)<br>16<br>(0.63) 12<br>(0.47) ioe<br>4p-re—i35—ol4 HS (0.09)2.4<br>**----- End of picture text -----**<br> **==> picture [50 x 76] intentionally omitted <==** **----- Start of picture text -----**<br> 13.5<br>(0.53)<br>5<br>=<br>LJ Two, M2 × 4<br>**----- End of picture text -----**<br> ## Precautions **! Caution** Avoid damage to the E3T: NEVER apply AC power to the E3T. ~~od”~~ 7 **AVOID DAMAGE TO THE E3T** a • Do not exceed the rated voltage on the E3T. ## **HIGH-TENSION LINES** To avoid Sensor damage or malfunctioning due to induction noise, do not place the power supply lines of the Photoelectric Sensor within the same conduit as power lines or high-tension lines. ## **CABLE** The cable can be extended up to 100 m provided that cable thickness does not exceed the 0.3 mm[2] maximum. - Do not short-circuit the load connected to the E3T. - When supplying power to the E3T, make sure that the polarity of the power is correct. ## **POWER SUPPLIES** ## **OPERATING ENVIRONMENT** To avoid malfunction, DO NOT install the E3T in the following environments: If a switching regulator is connected to the E3T, you must ground the FG (frame ground) and G (ground) terminals, or the switching noise of the switching regulator may cause the E3T to malfunction. - Locations where the E3T is exposed to intense sunlight. - Locations with high humidity and where condensation may result. - Locations with corrosive gas. - Locations with vibration or shock affecting the E3T. 15 **E3T** **E3T** ## **WATER RESISTANCE** - Do not use the E3T underwater, outdoors, or in the rain. - Use M2 screws and washers to mount the E3T. When mounting the E3T, NEVER strike the E3T with a hammer, or the E3T will lose its watertight properties. ## **LOAD SHORT-CIRCUIT PROTECTION** The E3T incorporates a load short-circuit protection function. If the load short-circuits, the output of the E3T will be turned OFF. Recheck the wiring and turn on the E3T again to reset the load short-circuit protection function. The load short-circuit protection function will work if there is a current flow that is 2.4 times larger than the rated load current. When using an inductance load, be sure that the inrush current will not exceed 2.4 times larger than the rated current. ## **INDICATORS** The following graphs indicate the status of each operation level. Be sure to use the E3T within the stable operating range. **==> picture [207 x 108] intentionally omitted <==** **----- Start of picture text -----**<br> Stability Operation indicator (orange)<br>indicator E3T- 1 E3T- 2<br>(green) E3T- 3 E3T- 4<br>Repetitive eet beneath ae<br>Stableoperationrange Operation peesbeaeHeROa Cerealcsescnnr ON eSBs «| PcsBesreeuanepoiuennaneSe8eaSR ON RISrrBeseos erSa OFF<br>level x 1.2<br>Unstableoperation Operationlevel OFF<br>range<br>Operation<br>Stableoperation level x 0.8 aeSoeee ON eeEee OFF eyaeee ON Ee<br>range<br>Light<br>**----- End of picture text -----**<br> ## **CLEANING** DO NOT apply paint thinner when cleaning the E3T. Paint thinner will damage the casing of the E3T. Note: When the E3T’s operation level is set to the stable operation range, the E3T will be in its most reliable operation without being influenced by temperature, voltage fluctuation, dust, or mounting changes. ## **TURNING ON POWER SUPPLY** - The E3T will be ready for sensing 100 ms after the power is turned ON. - If the E3T is connected to a power source different from one for loads, be sure to turn ON the power supply to the E3T first. ## **NOTE: DIMENSIONS SHOWN ARE IN MILLIMETERS.

When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
