Sensor Pocket Machining
Sensor pockets are machined into the ejector
plate. The pockets must be centered under
the selected ejector pin measuring 0.510”
+0.005/‑0.0 (13,0 mm +/‑0,10 [
1
at right ])
DIA, and 0.375” +0.003/‑0.0 (9,49 mm
+/‑0,01 [
2
at right ]) deep.
•
Use a 5/16” “dead sharp” end mill to achieve
correct radius—sensor pocket corner radius
MAX R 0.005” (0,10 mm [
3
at right ]).
If the ejector pin head DIA is greater than
0.50” (12,7 mm), machine a counterbore into
the ejector plate equal to the ejector pin DIA
plus 0.125” (3 mm) MIN by 0.02” (0,5 mm)
MIN deep to allow the head of the ejector pin
to clear the plate and rest only on the sensor
when under pressure (

INSTALLATION SPECIFICATIONS ( continued )
NOTE
Ejector pin head clearance not to
exceed 20% (1/5th) of part thickness at point of
pin/part convergence
Hole basis for ejector pins is ISO standard
clearance fit H7g6—H7g6 is a sliding fit suitable
for precision location fits.

Ejector Pin Pocket
Choose an ejector pin appropriate for the
application (refer to “Sensor and Ejector Pin
Size” on page 2). Machine a pocket for the
ejector pin head in the ejector retainer plate
that is equal to the ejector pin head DIA
plus
0.01” (0,3 mm [
6
at right ]) MIN per side by
ejector pin height plus 0.01” (0,3 mm [
7 i
at
right ]) MIN to eliminate potential preload on the
sensor when installed.
