• Voltage rating: 300 V AC, DC
• Temperature range: -25˚C to +85˚C
(including temperature rise in applying
electrical current)
• Contact resistance: Initial value/ 10 mΩ max.
After environmental tests/ 20 mΩ max.
• Insulation resistance: 1,000 MΩ min.
• Withstanding voltage: 1,500 VAC/minute
• Applicable wire: AWG #26 to #16
* Refer to "General Instruction and Notice when using
Terminals and Connectors" at the end of this catalog.
* Contact JST for details.
* Compliant with RoHS.
Note: The current rating differs depending on the number of circuits and the wire
size used in each connector. The table below lists the current rating as a
function of the number of circuits and the wire size.

This PSI connector is designed for wire-toboard and wire-to-wire 4.0 mm pitch
connector. Low insertion force type contact
is adopted and it provides excellent
operability. This connector has the secure
locking device that has the mechanism for
preventing the inverse insertion.
By adopting key shape and multi colors of
housing, prevention function of mis-mating
is considered.

Note: Do not branch in parallel current which exceeds the rated current (e.g. more than
12 A in the case of 2 circuits with AWG #12). If branched in parallel, current
imbalance or other problems may develop. If it is absolutely necessary to branch
such a large current in parallel, design the circuits without causing any imbalance
and provide an extra margin for each circuit.
