Current Transducer HMS 5..20-P
Handling Instructions
Notes for Storage, Handling and Mounting the transducer
Storage
( 1) General storage conditions: Temperature 5 .. 30 °C Humidity 40 .. 60 %RH without dew condensation
( 2) Storage period:
Storage period is within 1 year after production date in general storage conditions with dry pack dessicant.
According to MSL1 (Moisture Sensitivity Level 1) requirement.
( 3) Containers must prevent electric static charge build up.
N ote. For over storage periods of 1 year, the customer shall confirm the solderability of the part.
Handling and Mounting
( 1) Do not expose the transducer to shock or vibration.
Damage caused by shock or vibration can lead to a failure of the transducer.
( 2) Do not wash the transducer.
The HMS is a non-sealed type transducer. If liquids reach inside the transducer, it will cause migration or corrosion, which will
influence the performance.
( 3) Thickness of the PCB should be more than 1.5 mm.
If the thickness is not enough, the PCB tends to warp. It makes excessive tension on the transducer, which will influence the
dynamic characteristics.
( 4) Be aware of the chucking force when mounting the transducer.
When you use a machine for mounting the HMS transducer, make sure the chucking force is not too much because
excessive force could cause damage to the parts inside the case, which will influence the dynamic characteristics of the
transducer. Chucking force should not exceed 3 times the weight of the transducer.
( 5) Do not touch the lead pins with bare hands after they are taken out of the reel.
Lead pins of HMS are Pb free parts. If the pins are touched by bare hands, they will oxidize faster, and that could cause
soldering problems.
Do not use HMS transducer other than measuring current.
