NC3FXX-EMC-B
3 pole female EMC-XLR cable connector, black
The EMC-XLR Series is a specifically designed version of the XX
series to give enhanced RF screening for critical applications in
live performance and recording where there are particular
problems with radio transmission or mobile phones. The design
guarantees a continuous RF shield connection from the cable to
the chassis connector housing via a circular capacitor around the
cable shield. The circular capacitors act as high-pass filter with a
cut-off frequency around 10 MHz.
An EMI suppression ferrite bead with 24 Ohm at 1 MHz between
pin 1 and the cable screen provides a low-pass filter for
improved RF rejection.
Features & Benefits
3 pole male and female XLR cable connector with
integrated capacitive shield to shell connection
•Circular capacitor around the cable shield enables low-
inductive shield connection to connector housing
•
Female connector with circumferential ground spring
providing an accurate connection to the mating shell
•Cable shield - Pin 1 connection includes EMI
suppression bead to block high frequencies
•
Avoid ground loops as there is no LF-shield connection
to ground
•Rugged zinc diecast shell, long lasting and durable
•
Chuck type strain relief system for secure clamping of
cables
•Boot with rubber gland gives high protection against
bending stresses
•
Branded with unique hologram - guarantees genuine
and authentic Neutrik product
