Brand new receiver photocell (right side) for Necta vending machines: Sfera, Snakky, Rondo, Samba, Mambo (6735-432-00). 24 months warranty,
Why Choose Our Photocell Over the Original?
Our photocell delivers better quality at a lower price:
- Lower price — costs significantly less than the generic one
- Premium components — high-quality infrared receivers by Osram
- Intelligent algorithm — Advanced Autotune Calibration for superior performance in real-world conditions
- 24-month warranty
Advanced Autotune Calibration Algorithm
Original Necta photocells have a fixed sensitivity threshold — set once in the factory and never changed. In real-world use, this quickly becomes a problem:
- transmitter diodes weaken over time (burn out) → the infrared beam becomes too weak (the most common failure in the left/transmitter photocell)
- dust, dirt, and spilled liquids in the dispenser area interfere with the reading
- strong daylight (which also contains infrared) “blinds” the sensor
Result? The photocell system disables itself and you lose control over correct product dispensing.
We went one step further.
Instead of a rigid threshold, we developed the Advanced Autotune Calibration algorithm. The photocell automatically calibrates itself to current conditions — it measures the actual beam strength, compensates for diode wear and contamination. Thanks to this:
- it works reliably even with a heavily worn transmitter (left) photocell
- it flawlessly detects small items (e.g. candy, small chocolate bar)
- it eliminates randomness — every sale is reliable, no false refunds
How to spot a cheap replacement and avoid getting ripped off
We tested most aftermarket replacements available on the market. Almost all have serious design flaws:
- no protective coating → they start corroding after the first spilled cola in the delivery bin
- much slower barrier scanning (original: 160 µs; cheap copies: often 1–2 ms and more)
- random detection of small products → customer gets the item + money back
Classic symptom of a poor replacement
You vend a small item → sometimes it works fine, sometimes the machine doesn’t see the falling product and refunds the money. This is not a fault — it’s simply poor design that can’t keep up.
Our right photocell scans at exactly the same speed as the original Necta — 16 line pairs in 160 µs. A falling coin? Always detected.

How to distinguish right vs left photocell?
The right photocell has two connectors:
- smaller one – connected to the machine’s control board
- larger one – connecting it to the left photocell
The left photocell has only one connector.
Can I replace only one side?
Yes – absolutely.
