• 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.

SENSOR AND EJECTOR PIN SIZE
SELECTION CHARTS
The charts below are only a guide. In order to assure correct sensor selection for your application,
please contact RJG.
Locate the pin size that will be used and match it to the location on the part (near the end of fill or
near the gate). The recommended sensor is the intersection of the row and column.
