Selection Notes

This transponder shares its 24 mm body and stainless M8 (versus the smaller M6) thread with the shorter screw-in variant in the same range, but is twice the height at 20 mm, so it is the one to specify when the application needs a longer embedment depth into a thicker metal boss for extra mechanical retention. Torque and IP68/IPx9K sealing match the shorter M6 variant, so the choice comes down to thread size and embedment length rather than electrical performance.

Applications

The longer M8 body suits deep-drilled metal fixtures and heavy tooling in RF200/RF300 or MOBY D lines where a shorter M6 or M20 tag would not seat as securely.
