This application will require a button style sensor. You’ll also need to answer:
1. What is the diameter of the pin or width of the blade?
Strain Gage sensors are rated in pounds of force and can be overpressured and damaged if too large a pin is used with a low force rated sensor.
2. What is the expected plastic pressure at the intended sensor location?
Strain Gage sensors can be overpressured and damaged if too much plastic pressure is applied and the resolution can be poor if too low a pressure is applied.
3. What is the expected mold temperature?
Strain Gage and Piezo sensors have two components: electronics and the sensor element. The electronics for both must be kept below 140 °F. The sensor element for strain gage comes in standard (250 °F) and high temp (425 °F) models. The piezo comes in one standard temp (425 °F).
4. Is there enough non-interfered space behind the pin for a .505” inch sensor?
Only one pin can contact the sensor. Our most common model of sensors require .505” of space behind the ejector pin. We have a 6mm sensor (9211) for tighter fits and we have some alternate installation methods available.
5. How many sensors will be in the mold?
Single channel sensors work well for one- and two-cavity or sensor applications. Above two, we recommend our multi-channel line of products that reduce the connections and real estate on the mold.
