provides easy installation in the
tight environment of multiple-gate
molds.

temperature at the adaptor,
eliminating failures due to
overheating.

• The single tail with dual lead
feature occupies less space in
the wire raceway.

thermocouples to the sheath

provide temperature
measurement capabilities.

• Stocked sizes are available for
