NOTES

PRODUCT DESCRIPTION
The LES‑B‑127‑50/125/500/2000 line of
sensors from RJG, Inc. are multi‑channel,
digital strain gage, 0.50” (12,7 mm)
button‑style cavity pressure sensors that
can withstand forces up to 50 lb. (0.22kN),
125lb. (0.56kN), 500lb. (2.22kN), or
2,000 lb. (8.9kN) and temperatures up to
250°F (120°C—standard sensors) or 425 °F
(220°C—high‑temperature sensors).
The Lynx™ LES‑B‑127‑50/125/500/2000
sensor electronics and heads are
embedded into the mold, eliminating
outside cabling. Designed exclusively
for use with the RJG eDART® or Copilot®
Systems, all sensors are fully functional
and properly named with a single cable
connection from the mold to the eDART
or CoPilot process control and monitoring
systems.
One Lynx connector connects up to 16
sensors and to one system Lynx port (up
to 32 sensors per system—additional
sensors will require additional systems);
if more than 32 sensors are required
please contact RJG Customer Support for
additional information.
APPLICATIONS
MULTI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.
Sensor will be kept below 250 °F (120 °C)
for standard models or 425°F (220°C)
for high‑temperature models (LES‑B‑127‑
XXXX‑H) in the mold; sensor electronics,
regardless of model, will be kept below
140°F (60 °C).
CAUTIONaLES‑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.

OPERATION
BUTTONSTYLE/UNDERPIN
The Lynx single‑channel, button‑style strain
gage sensor is placed in a 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 measurement is carried
through the sensor cable, to the Lynx
sensor electronics case mounted inside 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 sensor are 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 sensor electronics 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.

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 diame‑
ter.
The sensor connector plate is mounted on
the mold. Pockets and a channel is ma‑
chined into the mold for the sensor con‑
nector, cable, and sensor head. The sen‑
sor head is placed under the transfer pin
above the cover plate in the clamp plate.
The transfer pin is retained below the ejec‑
tor 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 can‑
not be achieved, apply the head‑to‑head
clamp plate installation concept (refer to
figure at top right).
CLAMP PLATE HEADTOHEAD INSTAL
LATION
Apply the clamp plate (head‑to‑head) in‑
stallation 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 ma‑
chined into the mold for the sensor con‑
nector, cable, and sensor head. The sen‑
sor head is placed under the transfer pin
above the cover plate in the clamp plate.
The transfer pin is retained below the ejec‑
tor pin in the ejector plate, while the ejec‑
tor 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 54).
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 54).

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 0.510”
+0.005/‑0.0 (13,00 mm ±0,10 [ 1at right])
DIA, and 0.374” +0.002/‑0.001 (9,49 mm
±0,01 [ 2at 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 ( 5i
at right) for at least 0.50” (12,0mm) MIN.
INSTALLATION SPECIFICATIONS (continued)
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.
