Carbon Brush with Signaling Device

The pitch-bonded graphite material used features a resistance range of 35 to 3,000 μΩm and opens up a broad spectrum of uses for motors of all performance classes. This carbon brush features a signaling device which indicates to the user in good time (before the wear limit is reached) that the carbon brush should be replaced. The signal of the signaling device can be evaluated electronically. As a result, it switches off the motor electronically after a defined remaining operating time. In conjunction with a stop-motion mechanism integrated in the carbon brush, the motor can also be switched off mechanically when the defined remaining operating time is up.

You benefit from these advantages:

• Perfectly matched L-material for corded appliances
• Characterized by weak abrasive behavior and a broad resistance range
• High thermal and electrical resilience
• Great commutation and radio frequency interference (RFI) suppression properties
• Signaling device indicates a brush change
• Connection with stop-motion mechanism possible
• Enables a longer appliance service life
