Key Features:

• Passive inductive sensor design — operates without a separate power supply from the ABS control unit
• Generates an alternating current signal proportional to wheel rotational speed, enabling the ABS control unit to precisely modulate braking force
• Constructed to OEM specifications for reliable, long-service-life performance in demanding commercial vehicle environments
• Durable cable and connector construction resistant to vibration, moisture, and road contamination
• Direct OE-quality replacement engineered to meet or exceed original equipment standards
• Mounting hardware included for straightforward installation
