Product Manual | Lynx™ Multi‑Channel Strain Gage 4,000‑Pound Button Sensor MCSG‑B‑159‑4000
PRODUCT DESCRIPTION
The MCSG‑B‑159‑4000 sensor from
RJG, Inc. is a multi‑channel, digital strain
gage, 0.625” (15,88mm) button‑style
cavity pressure sensor that can withstand
forces of up to 4,000 lb. (17.79 kN) and
temperatures of 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 connector. The sensor
connector is housed inside the mold and
plugs into the Eight‑Channel MCSG Sensor
Plate SG‑8 on the outside of the mold.
All sensors are fully functional and properly
named with a single cable connection from
the mold SG‑8 plate to the Eight‑Channel
MCSG Sensor Adapter SG/LX8‑S‑ID and
eDART® or CoPilot® process control and
monitoring systems.
APPLICATIONS
BUTTONSTYLE 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.
• Sensor will be kept below 250 °F
(120°C) for standard models or 425°F
(220°C) for high‑temperature models
(MCSG‑B‑127‑XXXX‑H) in the mold; sensor
connectors will be kept below 185 °F
(85°C).
CAUTIONaMCSG-B-127-XXXX model sensors
MUST be used only within the
recommended temperature
ranges; failure to comply will result
in the damage or destruction of
equipment.

OUTPUT
STRAIN GAGE OPERATING PRINCIPLE
OPERATION
INDIRECT/UNDER PIN
Each Lynx™ multi‑channel strain gage
sensor is placed in the mold behind an
ejector pin. As plastic is injected into
the cavity, the pressure of the plastic
applies force 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 body 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 or measurement is carried
through the sensor cable, through the
SG‑8 plate and C‑SG/LX8‑S‑ID cable, to
the SG/LX8‑S‑ID adapter electronics case
mounted outside of the mold. The output
voltage signal is calibrated by the sensor’s
electronics and directly correlates with
pressure from within the cavity.
The SG/LX8‑S‑ID is connected to the
RJG, Inc. eDART system, which records
and displays the sensor’s measurement
for operator aid in process control. In
the eDART and CoPilot™ software, the
sensor model is assigned to each channel
in order to provide correct calibration.
This configuration only needs to be
completed once, after which the software
automatically recalls the configuration each
time the SG‑8 plate is connected.

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)

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).

1. Sensor Head Pocket
Sensor and transfer pin head pockets
are machined into the clamp plate. The
sensor pockets must be centered under
the selected ejector pin measuring 0.635”
+0.005/‑0.0 (16,13mm ±0,10 [ 1at right]) DIA,
and 0.500” +0.002/‑0.001 (12,7 mm ±0,01 [ 2
at right]) deep.
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.
