and secure mating with one push
Socket
Header
Lock
sFeatures
1. Easy and simple mating
Built-in locks assure correct and complete mating with a
single push on the plug.
qSecure
hold during the soldering operation
Insulator
2. Reduced space requirement
Vertical mating direction and built-in self-aligning features
eliminate the need for the extra space when mating / un-
mating.
Contacts
3. Designed for high voltage applications
Large contact pitch and the creepage distance maintain
stable and safe performance at high voltage levels.
4. Secure attachment to the board
Soldering at 4 points secure the headers to the board.
Hold-down
5. Secure hold during the soldering operation.
Through-hole termination header (12mm pitch only)
incorporates a hold-down feature to prevent dislocation
during the soldering operation.
qReduced
space requirement
(14.1)
6. UL, C-UL, and TÜV certified (12mm pitch only)
7. RoHS compliant
All components and materials comply with the
requirements of EU Directive 2002/95/EC.
