DESCRIPTION OF MODEL 321 ACCESSORY
2001
RJ-11 Cable Assembly
. Four-Wire Cable Assembly with RJ-11 plugs on each end. Used with
RS-232C Interface. Cable is 14 feet (4.6 meters) long. See Figure 5-1.
2002
RJ-11 to DB-25 Adapter
. Adapts RJ-11 receptacle to female DB-25 connector. Used to connect
Model 622/647 to RS-232C Serial Port on rear of Customer’s computer. See Figure 5-2.
2003
RJ-11 to DE-9 Adapter
. Adapts RJ-11 receptacle to female DE-9 connector. Used to connect
Model 622/647 to RS-232C Serial Port on rear of Customer’s computer. See Figure 5-3.
3003
Heater Output Conditioner.
The heater output conditioner is a passive filter which further
reduces the already low heater output noise of the Model 321. The typical insertion loss of for
the Model 3003 is 20 dB (at 10 µV) at line frequency, and >40 dB from double the line frequency
up. The Model 3003 is housed in a 144 mm wide by 72 mm high by 165 mm deep (5.67 x 2.84 x
6.5 inches) panel mount enclosure and weighs 1.6 kilograms (3.5 pounds).

Half-length mounting
panel and mounting ears to attach one Model 321 to a 482.6 mm (19-inch) rack mount space.
See Figure 5-4.
3026
Dual Mounting Shelf for Two Model 321 Temperature Controllers.
Mounting shelf to attach
two Model 321 Temperature Controllers side-by-side on a 482.6 mm (19-inch) rack mount shelf.
See Figure 5-5.

Lake Shore Cryogenic Wire
. Lake Shore sells the following types of cryogenic wire: DT =
Duo-Twist™, MN = Single Strand, MW = Manganin, NC = Nichrome Heater, ND = Heavy Duty,
QL = Quad-Lead™, and QT = Quad-Twist™. Please refer to the Lake Shore Accessories Catalog
for details.
9004-020
Apiezon
®
“N” Grease, 25 gram Tube
. General purpose grease well-suited for cryogenic use
because of its low viscosity. It is often used as a means of thermally anchoring cryogenic sensors
as well as lubricating joints and o-rings. Contains high molecular weight polymeric hydrocarbon
additive which gives it a tenacious, rubbery consistency allowing the grease to form a cushion
between mating surfaces.
9007-002
Indium Foil (5 Pieces).
Indium is a semi-precious non-ferrous metal, softer than lead, and
extremely malleable and ductile. It stays soft and workable down to cryogenic temperatures.
May be used as a sealing gasket for covers, flanges, and windows in cryogenic applications.
HTR-25
25
Ω
Cartridge Heater.
The heater features precision-wound nickel-chromium resistance wire,
magnesium oxide insulation, two solid pins, non-magnetic package, and has UL and CSA
component recognition. The heater is 25 W, 6.35 mm (0.25 inch) diameter by 25.4 mm (1 inch)
long. The 25 W rating is in dead air. In cryogenic applications, the cartridge heater can handle
many times this dead air power rating.
