• Sensor will be kept below 250 °F (121 °C)
for standard models or 425°F (218°C) for
high‑temperature models (LS‑B‑159‑4000‑H)
in the mold; sensor electronics, regardless of
model, will be kept below 140 °F (60 °C).
CAUTIONaLS‑B‑159‑4000 model sensors
MUST be used only within the
recommended temperature
ranges; failure to comply
will result in the damage or
destruction of equipment.
PRODUCT DESCRIPTION
The LS‑B‑159‑4000 sensor from RJG, Inc. is
a single‑channel, digital strain gage, indirect
(under‑pin), 0.625” (15,88 mm) button‑style
cavity pressure sensor that can withstand
forces up to 4,000 lb. (17.79kN) and
temperatures up to 250°F (120°C—standard
sensors) or 425 °F (220°C—high‑temperature
sensors).
The button‑style sensor has a permanent cable
which connects the sensor head to the sensor
electronics housing. The housing provides
not only the sensor’s electronics, but also the
connector which enables the interfacing of the
sensor with the eDART® or CoPilot® system;
the exclusive Lynx™ digital technology sensors
are designed for use with the RJG eDART
or CoPilot process control and monitoring
systems.
APPLICATIONS
SINGLECHANNEL SENSORS
Button‑style cavity pressure sensors are
suitable for injection molding applications in
which the following conditions are met:
• Sensor will be installed behind an ejector,
blade, or core pin.
• Applied plastic pressure is high enough
to prevent poor sensor resolution, but low
enough to prevent sensor damage.
• Only one point of contact (single pin) to the
sensor.

OPERATION
INDIRECT/UNDERPIN
The Lynx single‑channel strain gage sensor
is placed in a mold behind an ejector pin.
As plastic is injected into the cavity, force is
applied to the ejector pin; the plastic pressure
force is transfered to the strain gage sensor.
STRAIN GAGE SENSORS
The strain gage sensing element inside the
sensor boy converts the applied force to
an electrical signal that can read using the
eDART system or CoPilot system software.
The sensing element uses a Wheatstone
bridge configuration (four strain gage
elements positioned in a circuit) to convert
small amounts of sensor deformation into a
measurable voltage through the change in
resistance of the strain gage sensing elements.
The sensor sends out a low‑level voltage
signal which is proportional to the amount of
force applied by the pressure placed on the
pin and transferred to the sensor.
The voltage measurement is carried through
the sensor cable, to the Lynx sensor
electronics case mounted on the outside of the
mold. The voltage signal is converted by the
sensor’s electronics to a high‑accuracy digital
output that directly correlates with pressure
from within the cavity.
The Lynx case is connected to the RJG, Inc.
eDART System, which records and displays
the sensor’s measurement for use in process

monitoring and control. In addition, the Lynx
case communicates the sensor model, serial
number, full scale load, and calibration data
automatically to the eDART or CoPilot system,
providing the highest level of sensor accuracy
while minimizing the need for user‑entered
data when configuring the sensor in the eDART
or CoPilot systems.

CABLE LENGTHS
Length must be longer than needed to
facilitate safe installation and removal of
connector from tool to prevent tension on
the lead wire; generally, 2–3” (50–75mm)
of slack is sufficient. Use good sense to
determine the appropriate cable length
required for each application.

INSTALLATION
Sensors may be placed in the clamp plate
behind transfer pins, or in the ejector plate
behind ejector pins. Installation location—in the
clamp plate or ejector plate—depends upon
mold real estate and customer preference.
Transfer pins protect the sensor from damaging
shock loads that are applied when the ejector
plate moves forward and backward; the
sensor’s cable is also protected from pinching
since it is not necessary to disassemble the
clamp and backing plates during normal usage
or preventative maintenance.
Ejector pins provide a simple, straightforward
method of installation in which sensors may be
installed; ejector pin installation requires less
machining and less equipment to achieve.

INSTALLATION OVERVIEW
CLAMP PLATE TYPICAL INSTALLATION
Apply the clamp plate (typical) installation to
instances where the ejector and transfer pins
are less than 0.28” (7,0 mm) in diameter.
The sensor connector plate is mounted on the
mold. Pockets and a channel is machined into
the mold for the sensor connector, cable, and
sensor head. The sensor head is placed under
the transfer pin above the cover plate in the
clamp plate. The transfer pin is retained below
the ejector pin in the clamp plate. The ejector
pin is retained in the ejector retainer plate and
reaches through to the B‑Plate or cavity insert
(refer to figure at top right).
A minimum of 0.50” (12,0 mm) or one‑third of
the transfer pins length, whichever is greater,
must be fitted to a H7/g6 tolerance within the
clamp plate to ensure proper pin alignment and
to prevent possible bending. If 0.50” (12,0mm)/
one‑third minimum cannot be achieved, apply
the head‑to‑head clamp plate installation
concept (refer to figure at top right).

INSTALLATION
Apply the clamp plate (head‑to‑head)
installation to instances where the ejector and
transfer pins are greater than 0.28” (7,0 mm) in
diameter, or those in which a minimum of 0.50”
(12,0 mm)/one‑third of the transfer pin cannot
be contained above the transfer pin head in
the clamp plate.
The sensor connector plate is mounted on
the mold. Pockets and a channel is machined
into the mold for the sensor connector, cable,
and sensor head. The sensor head is placed
under the transfer pin above the cover plate
in the clamp plate. The transfer pin is retained
below the ejector pin in the ejector plate,
while the ejector pin is retained in the ejector
retainer plate, with both heads resting against
each other. The ejector pin reaches through to
the B‑Plate or cavity insert (refer to figure at
bottom right).

ANGLED EJECTOR PINS
Ejector pins that are located on angled
surfaces of a part can utilize sensors
depending on the angle of the pin. The
maximum pin angle that can be used with
sensors is 30° ( 1at right). Beyond 30°, force
is lost to friction as the pin is pushed sideways
against the mold steel instead of directly back
onto the sensor, which in turn can create errors
in sensor readings. If the angle is greater
than 30°, contact RJG customer support for
assistance in verifying suitability for use with
an RJG sensor (refer to “Customer Support” on
page 56).
CONTOURED EJECTOR PINS
Ejector pins that are located on contoured
surfaces of a part can be used on either
concave and convex surfaces ( 2at right)
provided the shape of the contour is
symmetric, as this cancels out any sideways
forces generated by cavity pressure pushing
on the pin.
Do not use an asymmetrically‑contoured
ejector pin if the net contour is greater than a
comparable pin with a 30° angle. If a contour
is unique or asymmetrical, contact RJG
customer support for assistance in verifying
suitability for use with an RJG sensor (refer to
“Customer Support” on page 56).

2. Transfer Pin Head Pocket
Choose an ejector and transfer pin appropriate
for the application (refer to “Sensor and Ejector
Pin Size” on page 2). Ejector and transfer
pin must be concentric within 0.030” (0,76 mm)
or 10% of ejector pin diameter—whichever is
smaller. Ejector and transfer pin diameter 0.25”
(7,0mm) MAX, and must be equal in diameter.
Transfer pin head pockets must be centered
under the selected ejector pin measuring the
transfer pin head height plus a clearance of
0.01” (0,3 mm [ 3at right]) MIN. Chamfer the
transfer pin head pocket at 45° ( 4at right) to
the lead‑in of clamp plate, and fit the pin with
an H7/g6 fit ( 5Iat right) for at least 0.50”
(12,0mm) MIN.

CLAMP PLATE (TYPICAL) INSTALLATION
NOTESLThere must be 0.50” (12,0 mm) MIN
clamp plate thickness above the
transfer pin head to transfer pin
clearanced exit, equaling 1/3 of the pin
length; if 1/3 pin length not possible in
clamp plate thickness, use head‑to‑
head concept on page 10.
Chamfer the lead‑in at 30° ( 6at right) to the
ejector plate for a depth which equals the
transfer pin DIA, and provide clearance for the
transfer pin in the ejector plate equal to pin
DIA plus 0.04” (1,0mm) if pin DIA is <0.12”
(3,0mm), or 0.06” (1,5mm) if pin DIA is >0.12”
(3,0mm). Transfer pin must be 0.01” (0,3 mm)
longer than nominal for initial fit, then adjusted
to obtain the correct height.
