Volume Discount

Terminal opening and connection portion both possess a 1.78-mm pitch grid array, small size, and high density. Terminals are constructed with a ribbon shape, making them strong against prying and ensured for 1,000 insertions and extractions.

[Features]
· Terminal opening and connection portion both possess a 1.78-mm pitch grid array for use with small electric devices.
· Terminals are constructed with a ribbon shape, making them strong against prying and ensured frequent insertions and extractions.
· Able to be press welded when bunched with 0.89-mm (.35°) pitch cable (No.30 AWG) in an attempt to reduce work effort.
· The dip connector, along with a construction that allows the grounding of electrical interference waves arising from the cable and connector on the circuit board surface, includes a circuit board snap stop.
· The cover case is made of a die cast zinc amalgam effective in blocking electromagnetic waves, and a receptacle side bracket is included for effective noise reduction.
· There are two types of cover case: hood type and lock (bevel opening) type. The lock type allows for single-action operation.
