WITH SERPENTINE CABLE THREADING CAPABILITY.
By increasing the number of times the circuit passes through the ferrite
core, the effective magnetic path is lengthened yielding a significant
increase in impedance. See page 6, figures 3 and 4. The gain is equal to
N 2 , the square of the number of turns, and depending on the circuit cable
load and frequencies involved, much of the increase can be realized.
Cables may be “looped back through” as shown at left; or, “looped over
the top” as shown at left (insert).
In an alternate configuration, separate cable circuits can be accommodated
without saturation. Three styles permit different approaches:
Each is available with an optional adhesive foam pad mounting base.
WITH UNIVERSAL MOUNTING STRAP.
up to 1.00” (25,4mm). Allows single location for RFI suppression for
multiple cables and wiring runs. Each circuit reacts independently with
the suppression material without saturation. Adhesive mount base also
provides a centered .203” (5,1mm) diameter hole for optional hardware
attachment. Quick-release closure clip allows easy addition or removal of
wires.
WITH INTERNAL FRICTION GRIP
ferrite suppressor. Assembles to cable prior to termination by threading
in one end and out the other. Neutral gray standard color. Five sizes
accommodate cable diameters from .200” to .430” (5,1 to 10,9mm).
The preferred alternative to cable over-molding, shrink tubing, taping, tie
wraps and other costly secondary installation operations. A drop of water
in the I.D. during assembly will facilitate sliding into position.
For situations where extremely high amounts of attenuation are needed and/or
multiple passes through a traditional ferrite I.D. are not practical or sufficient.
Simply wrap cable in a spiral around bar for optimum absorption.
WITH END PORTS FOR FLAT-OVAL CABLES.
assembly in fully enclosed nylon case. Two sizes: one for 4-conductor
and one for 6-conductor standard telecom flat-oval cable. Clamps around
cable with appropriate pressure to maintain desired position.
