Ouch!
Having an interference source that is only a slightly longer wavelength than
the RFID frequency is a real tough problem. If the bombarders are only
interfering with transmits/receives and not actual writing false data to the
pallet markers I would suggest altering the system programming to r
I didn't understand the first time around that the rf generator causing the
interference was the 400 kHz bombarder. Mr. Gibbs cleared that up. The
bombarders are used for induction heating. That creates a very strong
magnetic field. It is possible the 530 kHz receiver also uses a coil
antenna.
Hello Wm:
Troubleshooting an EMI problem by telephone or email is usually a very tall
order.
The best that could probably happen is for someone to point you in the right
direction.
1) I agree with Ken, a clue lies in the generator frequency
2) Does the problem occur only at the station where th
Hi:
I'm doing a study of sources of potential interference in the 10-12 MHz
range. I found that the EU allows inductive electronic surveillance systems
to co-exist with other spectrum users in the 10.2-11 MHz range. (See ERC
Report 92).
My question, as I know some of you folks work in this area,
You don't say what the rf generator frequency is. If it is also MF (300 kHz
- 3 MHz) ferrite tiles won't work. hard to give useful info without more
definition of the culprit emitter and its purpose. If the rf generator
drives a load through coax then it ought to be easy to shield it and contain
Without knowing anything about your system, RFID and RF bombarders, I will
merely offer a SWAG. My guess is that the RFID system is a magnetic loop
system? If so, copper will not have significant effect on shielding the
system. Ferrous material will. Try a galvanized sheet steel for a shield.

saying.
The only thing I had to make certain of during transfer
of names on documents in complete OEM agreements
(OEMs who wanted no mention of another company)
was the safety factory inspection agreements.

I attach an RF interference inquiry from a customer; I have no 'smarts' where
RF ID is concerned, so I turn to this august body...
==paste==We have an OMRON RFID data transfer system operating within the same
room as 12 RF generators (bombarders). The transmission frequency for the RFID

background than I have). I have no additional information. Please reply

Good luck,

Transfer of EMC CertificationThanks Gary,
But remember that color is dye specific and adding dye will affect the
flammability of certain plastic types.
I agree that Solar radiation will need to be reassessed but don't forget
EMISSIVITY for indoor and outdoor equipment. One of my first engineeri
I agree and have done the same. Except I'm not sure why color is even
mentioned - it doesn't belong in any agency report I can think of. I suppose
the possible exception might be for outdoor equipment that absorbs solar
radiation and heats up.

Hi all,
Does anyone know of a list of rules and regulations for the disposal of
nickel metal hydride batteries, I've search through the environmental
restrictions but the only requirements I can find seem to indicate batteries
that contain hazardous materials.
I am particularly interested in the
