Strain Relief
The strain relief portion of the oven sample rod is made of white Delrin plastic. When you
install the sample rod, grip it by the strain relief portion.
This portion of the rod is designed to prevent damage to the wiring as it is fed into the shaft
of the oven sample rod. It also protects the wiring while the oven sample rod undergoes
vibration.
Important:
Always grip the strain relief portion of the oven sample rod when you insert or
remove the rod from the VSM.
Never
grip the cable of the oven sample rod while you
remove it, as you might pull the electrical connections loose.

Magnetic Lock
The magnetic lock is constructed of anodized aluminum. The lock contains six small, very
strong magnets that attach the oven sample rod to the armature of the linear motor transport
during measurement. Keep the magnets clean and prevent them from contacting any
magnetic object.

Electrical Connections (Bottom)
This electrical connector is the bottom of the wiring that feeds through the oven sample rod.
It connects to the oven heater stick and contains a five-pin female connector.
5.2.3 Wired Access Port
Figure 5-3. Wired access port
Figure 5-3 shows the wired access port that connects to the VSM linear motor transport. The
access port is made of aluminum and is designed to be vacuum tight. The oven sample rod is
connected to the oven-control cable by an electrical connector that can be seen on the back of the
access port (inside and outside). This connector is specially designed: it maintains its vacuum seal
and it is free to rotate. Hence, you can connect it to the oven sample rod without twisting the
wiring of the rod.
On the bottom of the wired access port is the flange attachment port. This section of the access
port has a hole that allows the oven sample rod to slide through and establish a magnetic lock
with the VSM linear motor transport. This port screws onto the top of the VSM linear motor
