This units can be used in any electromechanical system that requires unrestrained,continuous rotation while

power or data  from a stationary to a rotating structure.It's also called a rotary electrical

interface,commutator,collector,swivel or an electrical rotary joint.It can improve electromechanical capability,simplify 

system

design,eliminate possible damage while rotation.It's the key apparatus of various precision rotary worktable, electric test

instrument,manufacture and process control instrument.

The KYH38 series provide an economical, readily available solution when a compact through-bore configuration is

required. This unit provides a 38.1 mm through-bore for routing hydraulic or pneumatic lines and a compact 99 mm outside

diameter for minimal space applications. This series are available in 6, 12, 18 and 24 ring configurations in 4 housing 

lengths.

Similar in design to our very popular KYH38 series, this design features long life, fiber brush contact technology for 

ultimate

performance in many challenging applications. Fiber brushes do not require lubrication and produce virtually no wear debris,

for maintenance free, life time operation.

Features:

■ 6, 12, 18 and 24 circuits models

■ Precious metal contacts

■ 2, 5 ,10 ,15 amps rings

■ Precision ball bearings for long life

■ Speeds up to 500 rpm continuous

■ Compact size

■ Sealed units available
