Applications: Measurement of Temperature, Torque, Speed, and Position on Rotators Using Slip Rings

■ Enables detailed tracking of temperature, torque, speed, and position while supplying power to driving parts and heat sources on rotating bodies.

■ High demand exists for slip rings that are compact, lightweight, support multi-pole configurations, offer long service lives, provide high quality, and handle a wide range of rotational speeds from low to high.

■ We can also configure factory-default settings on the measuring instruments to match your sensors or amplifier outputs and provide a custom configuration reference sheet.

Measurement Examples Using Slip Rings

■ Measuring Internal Temperature and Rotational Speed of Agitation Tanks

Chemical mixers, pellet melting machines, roasting machines, etc.

■ Measuring Temperature and Rotational Speed of Heat Rolls

Large printing presses, sheet film manufacturing equipment, etc.

What is a Slip Ring?

A slip ring is a rotary electrical connector that transmits power and electrical signals from a stationary structure to a rotating body.
It operates through continuous sliding contact between stationary metal brushes and rotating metal rings.

Hollow Type

Shaft-End Type

Built-in Encoder Type:
Saves Installation Space

Advantages of Slip Rings

■ Eliminates cable twisting, shaft tangling, and wire breakages

■ Ensures uninterrupted power transmission and communication

■ Customizable combinations of pole counts to suit signals, power, or control needs

Without a Slip Ring... (Lead wires only)
The wiring between the rotating and stationary sides becomes tangled around the shaft, causing rotation to stop or wires to break.
With a Slip Ring...
By routing connections through a slip ring, power and signals are successfully transmitted without wiring tangles.
