Specifications –––––––––––––––––––

• Current rating: 12 A AC, DC (Refer to the following table.)

• 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 m

Ω max.

After environmental tests/ 20 m

Ω max.

• Insulation resistance: 1,000 M

Ω 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.

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.

PSI CONNECTOR

4.0mm pitch/Disconnectable Crimp style connectors

This PSI connector is designed for wire-to-

board and wire-to-wire 4.0mm 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.

• Secure locking structure

• Mis-mating prevention mechanism by keying

(2 to 4 circuits/3 kinds of keying)

• Finger-friendly design

• Large electric current was realized.
