EJECTOR PLATE INSTALLATION
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 ejector pin in the ejector 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 right
).
ANGLED EJECTOR PINS
Ejector pins that are located onto angled
surfaces of a part can utilize sensors depending
upon the angle of the pin. The threshold for
angled pin and sensor compatibility is 30°
(

at right
) provided the shape is symmetrical
to allow force from plastic pressure to properly
be applied to the pin surface. Beyond 30°, force
is lost to friction as the pin is directed sideways
into the mold steel instead of directly back onto
the sensor. This effect will be magnified by
smaller pins that are subjected to lower forces.
If the angle is unique or non‑symmetrical,
contact RJG customer support for assistance in
verifying use acceptance with RJG sensor (refer
to “Customer Support” on page 54).
CONTOURED EJECTOR PINS
Ejector pins that are located onto contoured
surfaces of a part can utilize sensors depending
upon contour shape—concave and convex
contours are acceptable (

at right
) provided
the shape is symmetrical to allow force from
plastic pressure to properly be applied to
the pin surface. If a contour is unique or
non‑symmetrical, contact RJG customer support
for assistance in verifying use acceptance with
RJG sensor (refer to “Customer Support” on
page 54).
Do not use a contoured ejector pin if the shape
is comparable to an asymmetrical angle of
+30°, which loses force to friction on the pin
sides instead of the pin face.
