KHAU
Users should thoroughly review the technical data before selecting a product
part number. It is recommended that users also seek out the pertinent
approvals files of the agencies/laboratories and review them to ensure the
product meets the requirements for a given application.
Features
• Miniature size from 2 pole to 4 pole.
• KHAU is produced on an automated line, while KHU is produced
manually. Form, fit and function of the two versions are identical.
• Various applications include process control, photocopier, and data
processing.
• Push-to-test and indicator options available.
• Various contact materials available for specific load requirements.

Caution:
Printed circuit sockets are manufactured with
"floating" (Loose) terminals. This permits them to align
with holes in the circuit board and with the relay terminals.
During the mounting and soldering of the socket, vertical
float should be eliminated and the terminals seated on the
board. (This may be accomplished by inserting a dummy
relay in the socket.) Failure to eliminate float may cause
fracture of the solder joint or separation of the copper
conductor from the printed circuit board when a relay is
inserted in the socket after soldering.
