Influence Of Background Metal On Id Tag; Influence Of Noise - Omron V640 - MANUAL 2 User Manual

■ Influence of Background Metal on ID Tag

Metals in the vicinity of the communications area will affect the range, making it smaller.
Refer to page 115.

■ Influence of Noise

This CIDRW system uses a frequency of 134 kHz for communications with ID Tags. Equipment such
as switching power supplies, inverters, servomotors, or monitors in the surrounding area will adversely
affect communications, restricting the communications area.
The noise levels in the vicinity of the CIDRW Head can be determined with the environmental noise measurement com-
mand (applies only when SECS is not used)
For details on the relationship between noise and communications distance, see Appendix
