DETAIL 2.2: PROXIMITY SENSOR WIRE UP INSTRUCTIONS:
DETAIL 2.3: OPTIONAL WIRE-UP—WHEN INJECTION MOLDING MACHINE CANNOT SUPPLY POWER
 Not all injection molding machines are equipped to supply power to the proximity sensors. The proximity sensors are highly accurate, high-pressure,
inductive sensors which have no moving parts. Inductive sensors require power to deliver a signal. If dry contacts are required, an external power supply
and relay circuit will be required with the BHS006Y (NPN, NO) or BHS006U (PNP, NO) proximity sensors. A suggested electrical schematic is shown
below. This suggested circuit can be used with either NPN or PNP proximity sensors. Voltages shown are suggested only. Please refer to the voltage
range specified for the sensors on the previous page. The molder is required to provided the electrical service required to operate the sensors.
 When servicing the HLCP cylinder assembly, ensure that proper signals are received from both the front and rear mounted proximity sensors. Check the
condition of the proximity sensor wires. If wires are found to be damaged, the sensors will need to be replaced. Follow the sensor installation information
provided on the previous page.
 If you intend to use external limit switches in your mold, and do not intend to use the proximity sensors, threaded plugs (to replace the sensors and plug
the threaded holes in the cylinder body and cylinder cap) are available upon request.
NPN, NO (normally open) proximity sensors are supplied standard
with product. These sensors are inductive sensors and will require
power to operate.
PNP, NO (normally open) proximity sensors are optional and must be
requested at the time of the HLCP cylinder assembly order. As with
the NPN sensors, the PNP sensors are inductive sensors and will
require power to operate.
