1. General Notes
• Sensor ø6 mm and end faces may not be machined
• Front of sensor must be clean and without notches
• Do not use cable to pull sensor out of hole
2. Important Areas of Sensor Hole
Note the following critical installation criteria:
1. Hole with H7 tolerance to center sensor
2. Sensor contact surface blind hole shown must be flat and
perpendicular
3. Sensor must clear this surface
4. Surface higher than or level with sensor end face
3. Hole
The force sensor measures the cavity pressure via an enjector
pin. The sensor is installed in a hole with a thrust washer as
described in Chapter 3.1.
In a multi-cavity application where the sensor layout is sym-
metrical, sensors are held within in a machined spacer plate.
This allows for an easier and very accurate installation. De-
scription in Chapter 3.2
• Hole and channel free of debris and shavings
3.1 Sensor Seating
3.1.1 Sensor in Ejector Base Plate
Machine H7 hole and channel in ejector base plate. Check
depth of blind hole to hold thrust washer Type 9411; Sensor
shoulder must lie clear of channel. Check centering and
alignment. Centerline of ejector pin must be at right-angles
to sensor face.
9211B_002-414e-10.15
• Always use thrust washer Type 9411
3.1.2 Sensor in Spacer Plate
Machine H7 hole and slot in spacer plate. Spacer plate and
base plate must be machined flat. Centerline of ejector pin
must be at right-angles to sensor face. Sensor contact surface
must be flat.
D* = 0,5 mm larger than head
3.2 Ejector Pin and Guide Hole
Use ejector pin with tolerance class g6 and machine H7 hole.
Pin guide-length h as per drawing. Reduce friction with a
tribological finish or DLC (diamond-like coating).
Keep edges of rectangular ejector pin sharp and use radii
in hole. Do not engrave or mark the bearing surface of the
ejector head.
• Use guide length of twice pin diameter d
• Do not engrave or mark the ejector pin bearing
surface
• Pin diameter ød
• Treat pin with tribological finish or DLC
• Ejector pin head d
ø6 mm

4. Cable Channeling and Connector
• Fixed cable reduces mounting
• Chamfer all sharp edges
• Cover open channels/slots
4.1 Single-wire technique
The single-wire technique uses the tool steel of which the
mold is made to ensure an electrical shielding of the sensor
signal. Thus the wiring is run through drilled holes.
• Single-wire cable must be completely enclosed in the
mold
• Single-wire cable must not be run together with
power cables
• Refer to Chapter 4.2 for machining of channels
4.1.1 Single-wire Cut and Grip Connector Type 1839
Machine cable channel and recess for mounting plate.
Example shown: Drilled hole
4.1.2 Multi-channel Single-wire Connectors
Recess for 4-channel connector Type 1708...
Recess for 8-channel connector Type 1710...
4.2 Coaxial Cable
Machine cable channel and recess for mounting plate.
• Observe radii
• Cover open channels/slots
5. Installing Sensor
• Ensure all sensor hole and threads are clean
• A chamfered cable channel or cable hole prevents
damaged cables
