HIF3B Series MIL Standard-Compliant Ribbon Cable Connector

Caution
Product Description
MIL standard-compliant rectangular ribbon cable connector.
[Features]
· HIF3B series products are developed to comply with the MIL standard and can be used in a wide range of applications.
· Compatible with HIF3 series.
· HIF3B series products are UL-listed connectors.
· Features a mechanism to prevent mis-insertion.
· A form in which inserting the guide key (polarity key) on the pin header side creates a convex section that fits into the concave section (polarity keyway) of the socket. (MIL standard)
· A form in which the mis-insertion prevention guide (polarity guide) on the socket side fits into the slot (polarity slot) on the pin header side.
· A system that embeds the polarizing key in the socket hole and guides it.
· A guide system in which the convex section on the socket side (HIF3A type) combines with the slot located in the center of the pin header side.
· The compatible wire (UL2651) is an AWG#28 ribbon cable (7-core/0.127 mm, jacket diameter of 0.9 ± 0.2 mm).
[Applications]
· A wide variety of models are available, enabling use with a wide range of equipment.

(Note 1) This includes temperature increases caused by the flow of current.
(Note 2) The term "storage" refers to products stored for long periods of time prior to mounting and use. The operating temperature range and humidity range covers non-conducting condition of installed connectors in storage, shipment or during transportation.
(Note 3) Be aware that deformation may occur to the pin header type lock if an excessive load is placed on the inside of the lock.

Product Usage
Socket Side (Crimping) Assembly Method
Crimping method
Dedicated tools compatible with each terminal are necessary for connecting crimped contacts.
Contact insertion method
After confirming the crimping contact orientation, insert all the way to the back of the insulation case.
After inserting, lightly pull on the cable to confirm whether the contact lance is firmly fixed into the insulation case.
