Thin wire coaxial connector for small portable devices
a:


The smallest board mounting space in the industry (compared with other 0.4mm pitch product) with 2.5mm depth, 21.7mm pitch direction (for 40 pins), and 1.58mm height.
b:
Ensures 0.4mm effective contact length and stable connection.
c:
Highly reliable structure by supporting the contact points with contacts
d:

Ensures low contact resistance with Gold plated ground contact points between plug and receptacle with stable connection.
e:
Mis-mating prevention structure
f:
Compatible with AWG #44 and #42 cables
<Receptacle>
a:Available on embossed tape for automatic mounting and ensures high mounting performance with adsorption cap.
b:Solder migration prevention structure by Nickel barrier on receptacle plug
<Plug>
a:Small hinge can be passed through after harness processing.
