VDO Gauges 226-633 Reed Switch Fuel Sender 330mm 240-33 Ohm

The VDO 226-633 is a precision-engineered reed switch fuel sender designed to provide accurate fuel level readings in marine, automotive, and industrial applications. This 330mm (13-inch) sender utilizes reliable reed switch technology to deliver consistent signal output as fuel levels change.

Key Features:

• Reed switch technology for precise, reliable fuel level sensing
• 330mm (13-inch) length fits a wide range of tank depths
• 240-33 Ohm resistance range compatible with VDO fuel gauges
• Durable construction designed for long-term performance in fuel environments
• Direct replacement for OEM fuel senders with matching specifications

This sender works by using magnetically-activated reed switches that change resistance as the float arm moves with fuel level changes. The 240-33 Ohm output range is specifically calibrated to work with VDO fuel gauges and other instruments accepting this resistance specification. The 330mm length makes it suitable for medium-depth fuel tanks commonly found in boats, RVs, and custom fuel systems.

Installation Note: Verify tank depth and mounting configuration before installation. Sender length should be measured from mounting flange to bottom of float arm in the down position.
