Sensor Pocket Machining
Sensor pockets are machined into the
cover and ejector plates. 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. In
the cover plate, the pocket must equal the
ejector pin DIA plus 0.10” (2,54 mm) if the
DIA is greater than 0.50” (12,7 mm [
3
at
right]).
•
Use a 5/16” “dead sharp” end mill to
achieve correct radius—sensor pocket
corner radius MAX R 0.005” (0,10 mm [
4
at right]).
Additionally, if the ejector pin head DIA
is greater than 0.50” (12,7 mm), machine
a counterbore into the cover and ejector
plates 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 (

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 [
7
at
right]) MIN per side by ejector pin height
plus 0.01” (0,3 mm [
8
i
at right]) MIN to
eliminate potential preload on the sensor
when installed.

EJECTOR PLATE INSTALLATION
Hole basis for ejector pins is ISO standard
clearance fit H7g6—H7g6 is a sliding fit
suitable for precision location fits.
