## ■ **Features** 

- Dust-proof model. 

- Pre-wired Sensors (AWG28). 

- Solder-less lead wire connection to increase reliability. 

## ■ **Absolute Maximum Ratings (Ta = 25**  **C)** 

||**Item**|**Symbol**|**Rated value**|
|---|---|---|---|
|**Emitter**|**Forward current**|IF|50 mA<br>(see note 1)|
||**Pulse forward cur-**<br>**rent**|IFP|1 A<br>(see note 2)|
||**Reverse voltage**|VR|4 V|
|**Detector**|**Collector–Emitter**<br>**voltage**|VCEO|30 V|
||**Emitter–Collector**<br>**voltage**|VECO|5 V|
||**Collector current**<br>**Collector dissipa-**<br>**tion**|IC<br>PC|20 mA<br>100 mW<br>(see note 1)|
|**Ambient tem-**<br>**perature**|**Operating**|Topr|–25C to 80C|
||**Storage**|Tstg|–25C to 85C|



- **Note: 1.** Refer to the temperature rating chart if the ambient temperature exceeds 25  C. 

   **2.** The pulse width is 10  s maximum with a frequency of 100 Hz. 

   **3.** If you mount the Sensor with screws, use M3 screws, and flat washers and use a tightening torque of 0.5 N·m max.
