HI all,

my speedo uses a Turck Sensor but it's died.

anyone know of a good cheap source? beer tokens waiting if it's you

it's sensor

Ni3-EG08K-AP6X
Ident Nr. 4669600

the one with the lead attached.

many thanks

Neil

If it helps that is a standard inductive proximity sensor, normally used for industrial applications. Lots of other manufacturers make compatible sensors, the important points are that you want an open collector PNP output and the switching frequency needs to be high enough (3000 Hz for the Turck sensor, but you may not need to go this high depending on gearing and wheel size etc.).

The major electronics component sellers such as RS Electronics and Farnell will likely have something suitable, but a trawl through eBay for "proximity switches" or "proximity sensors" will likely yield a cheaper solution.


EDIT: IMO AE1/AP-2A Proximity Sensor 10-30Vdc NO PNP 3 wire | eBay UK looks as though all main parameters are compatible but please check the datasheet for yourself first!


EDIT: Arrgh, I HATE the STUPID automatic ebay link mangler, why was this added to the forum?

thanks Mike. i'll have a look. can i be cheeky and ask if you can suggest any? electronics is very much a bad point for me.

i thought i shoud be looking at the volatge drop etc...

Just edited my post to include a suitable sensor on eBay.

see this is why I like Locost Builders.

thanks so much!

No, that example has an NPN output which likely won't work as a direct replacement. With an NPN output the sensor connects the signal wire to ground when it senses metal. With a PNP output the sensor connects the signal wire the the positive supply. The two are not directly compatible.

EDIT: this makes no sense now! I was referring to the suitability of the device you had linked to in your post, not the one in mine!

the one i have says it is a PnP on the packet i have and the ebay link says PnP so i think there the same

I found the data sheet for the one i have here http://www.datasheetarchive.com/NI3-EG08K-AP6X*-datasheet.html#

they look the same enough to me

Our posts have crossed again! The 'IMO' sensor I linked to should be fine for your application.

perfect, then we are in agreement!

thanlks again

Your best bet for getting good pricing & support is via a local distributor. RS Electronics and Farnell are large distributors that cover the whole country. They usually get the product lines because they can place large orders with the manufacturer. Their tech support people may not have a clue about the products. They are mostly order takers.

Here's my local TURCK distributor.
