## Description

Photoelectric Switch;Sending Light : Infrared Rays;Model :E3F-5DN1;Wire Type : DC 3 Wire, Proximity-sensing / Opposite Type;Type : NPN NO ;Voltage : DC 6-36V

Review: good value; better range than expected - I'm not used to things working better than they claim. Running both ends at +12V DC, this Tx-Rx set worked all the way out to 51 feet, which is 15 meters. (That was the limit; it didn't work beyond that.) They only advertise a 5 meter range, so that is 3x better than the spec. Pointing accuracy at both ends was critical, of course, at that range. I notice it draws more current at higher voltage, so I'm guessing range would drop if you only run 6V instead of 12V. Both ends have a visible red LED. The transmitter side LED is always on, while the receiver side LED is on only when the beam is NOT detected.
Review: Photosensor straight through - I use this photo sensor in my cage/trap and it works great.

## Questions & Answers

**Q: Can this be used on a 3 foot wide 350°F conveyor belt or would the heat interfere with the infrared light.**
A: First off, this sensor would need to be protected against heat.  The cabling and housing would be adversely affected.  Glass fiber cabling is highly recommended, in high heat applications.  Apart from that, only trial and error and placement at the longest distance possible will determine the accuracy.  These sensors give us great results on conveyor applications.  The response time is very quick.

**Q: Are the right angle brackets available by themselves?**
A: If you sneak into the warehouse in the middle of the night.

**Q: Can someone recomend a 5-6 didget counter that works with this switch? 12-volt dc would be nice. thanks.**
A: Is this product ASIN:B07R1YB176 what you want? DC12v 0-999999 Digital LED Counter.

**Q: Can this be used on an esp32 node mcu?**
A: You'd better judge according to the working principle of your machine and the working parameters of our switches

### ⭐⭐⭐⭐⭐ good value; better range than expected

### ⭐⭐⭐⭐⭐ Photosensor straight through
*by B***3 on May 26, 2025*

I use this photo sensor in my cage/trap and it works great.

### ⭐⭐⭐⭐ Great once you figure out a compatible relay.
*by J***S on November 28, 2020*

The range is far greater than 5m. The model number suggests max of 18 meters. I am using it for 10 meters and there are no probs. Like most of the inexpensive thru beam sensor sets, it will not operate a mechanical relay. Use a relay with hi lo level and set it for low level trigger. Brown wire to positive, blue to negative and black to relay trigger. Do not expect decent documentation.
