FAQs

• What makes this model unique?

0.5 in unthreaded length, 3.0 in case, 5.0 m cable, standard ClickLoc connector, full hazardous approvals.

• Can I use this with any Proximitor?

No. This 5.0 m probe works only with the matching 5 m Proximitor sensor.

• When to use unthreaded length?

The 0.5 in unthreaded section allows the tip to extend before threads begin, useful for special mounting.

• Compatible with 3300 XL systems?

Yes, but only with the specific 5 m Proximitor sensor.

• What if I exceed thread engagement?

Can damage probe. Stay within 0.563 in limit.
