Baumer Hubner TDP Tachogenerator Brush Set - ET02.1057L (11076778)

Genuine Baumer Hübner carbon brush set for TDP tachogenerators, used to restore accurate speed feedback and resolve signal instability caused by worn brushes.

This genuine OEM brush set is used in maintenance and repair of TDP series tachogenerators to ensure reliable operation in closed-loop drive systems.

Key Features

• Genuine Baumer Hübner carbon brush set (ET02.1057L / 11076778)
• Supplied as 2 × twin-brush assemblies (graphite H7 / silver-graphite S7)
• Original manufacturer configuration for TDP tachogenerators
• Maintains stable electrical contact and signal accuracy
• Designed for maintenance and replacement of worn tachogenerator brushes

Technical Specification

• Brush type: Carbon (graphite and silver-graphite)
• Configuration: 2 × twin-brush assemblies (H7 / S7)
• Total brush elements: 4
• Dimensions: 4 × 5 × 8.5 mm

Compatible Models

Designed for use with Baumer Hübner tachogenerators including:

• TDP0.2
• TDP0.09
• TDPZ0.2
• TDPZ0.09
• Other compatible TDP series units

Quantity Required

• 1 set required per tachogenerator
• 2 sets required for double (tandem) tachogenerators

Many TDP units are fitted as double tachogenerators - ensure the correct quantity is ordered

Why two different brush grades?

This set includes two twin-brush assemblies using graphite (H7) and silver-graphite (S7), as specified by Baumer Hübner.

The combination of these materials provides:

• stable electrical conductivity for accurate signal output
• controlled wear characteristics
• improved commutation behaviour

This configuration is part of the original tachogenerator design and should not be substituted.

Applications

Used as a replacement part in Baumer Hübner TDP tachogenerators, which are commonly installed for speed feedback in:

• DC and AC motor control systems
• Legacy variable speed drive systems using analogue feedback
• CNC machinery and industrial automation equipment
• Retrofit and maintenance of older closed-loop systems
