Greetings,

Just spent two hours searching for an Inductive Proximity Sensor.

Plenty out there; but, I need one with a long, 2 meter, cable.

LJ12A3-4-2, I think is the part code.

I do know it is 12mm diameter x 60mm long.

NPN NO

Three wires, blue, black, and brown.

Please send me a link to a source.

With kind regards,

Dave in the USA

This was the cheapest I found that meets your requirements at about $18, not sure what sensing distance you need but automation direct sells the same sensor with other sensing distances for about the same price.

If you are willing to use a sensor with a quick disconnect you can get a cable up to 7 meters.

Why not extend the cable?

(Or take the cables to a small intermediate junction box so that you don't have the same problem next time)

Greetings,

Went to Automation Direct and purchased a new sensor. Wow, what a selection and they speak English.

Anyway, I have the new sensor and it is a "shielded" model. That is, the metal case goes all the way up to the "sensing" end. The old broken sensor appears to be the "non-shielded" variety. Where the metal case leaves about 4-5mm of plastic sensor on the end.

Not being an electrician, what is the difference between the two? The specification sheet lists the shielded as having 4mm range and the non-shielded at 7mm range.

The sensor is used to detect the HOME position of my mill.

Also, Automation Direct was very Customer focused and the sensor I received was Made In Germany. Shipping was also quite reasonable. I would recommend them to other users.

Cheers,

Dave

The "shielded" type will work when embedded in metal with only the surface visible. The other type, if you put them in a hole in metal will detect the hole itself and never "un-trigger"

I'm glad you enjoyed the experience, I have had nothing but positive experiences with automation direct. Their products don't quite compete with Allen Bradley or Siemens, but the work just as reliably in my experience and cost a fraction as much.
