Retainer
Housing lance
Panel lock
Inner lock
The retainer features added protection
against non-insertion or disconnection.
Features–––––––––––––––––––––––
• Housing lance
The resilient plastic housing lances secure the contacts in the
housing. Since the lances are in the housings rather than on the
contacts, they are not affected by handling, and allow the contacts to
be lightly inserted without undue force. This establishes a feeling of
uniform insertion and a noticeable change in that feeling when
insertion is completed.
• Secondary retainers
The secondary retainers enhance safety in case of partial
insertion or accidental release of the contact. Even if a contact
is inserted incompletely, the retainer guides the contact to the
proper position and securely locks it in place (except for
connectors with three row construction and when AWG #16
wire is used.)
• Inter-housing lock
This inter-housing lock secures the plug to the receptacle and
prevents accidental disconnection. The lock is protected and
is not affected by external forces that might result from the
routing of wires.
• Panel lock construction
Our unique compact panel lock is designed to prevent tangling
with wires and accidental breakage because of handling.
Specifications ––––––––––––––––––
• Current rating:
10A AC, DC max. (7.0A when retainers are mounted)
• Voltage rating: 300V AC, DC max.
• Temperature range: -25˚C to +90˚C
(including temperature rise in applying
electrical current)
• Contact resistance: Initial value/7m Ωmax.
After environmental testing/10m Ωmax.
• Insulation resistance: 1,000M Ωmin.
• Withstanding voltage: 1,500V AC/minute
• Applicable wire: AWG #26 to #16
0.13 to 1.25mm2
• Applicable panel thickness: 0.7 to 2.0mm (.028"to .079" )
* Contact JST for details.
Note: The current rating varies 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.
