I got a customer with a broken photoelectronic sensor (wire broken), and it seems to be hard to get by a new one. It's produced by Tippkemper, which is still in action, and I assume it to be a product somewhat near year 2000, but not certain about this.

<b>The application</b> is sensoring in the process of corrosion treatment(painting) of steel beams, and the sensor pairs (2 pairs, 4 sensors in total) are located inside the paint box. Each sensor pair consist of 1 transmitter and 1 receiver. While triggered, i.e. there is something between the two sensors, the machine spray paint on the object.

<b>Model name</b> is Tippkemper AX-S-25-P30-S74.

AX: Atex certification class 1+2
S: Transmitter (Sender)
25: 25m range
P30: 30mm circular design
S74: ??

<b>Additional information: </b>
* 3-wire connection to Tippkemper Matrix power supply
* Nominal voltage: 13,6
* Nominal power consumption: 800mW

I'm thinking about 2 options:

<b>1.</b> Finding an exact replacement, which seems to be hard to come by. I've found an item on ebay which is close in model name, but misses the S74 ending of it

<b>2.</b> Buying something from a new vendor, which probably must include transmitter + receiver + power supplies.

I would be grateful for any suggestions in this matter.

It seems that Tippkemper isn't widely known.

 

I'm still searching for a solution here, and would be happy for advice.

 

Just letting you know, Tippkemper still provide this item for sale.
