McNeilus Electric Switch Drum Magnetic Sensor

McNeilus Electric Switch Drum Magnetic Sensor

This is a magnetic proximity sensor, commonly known as a 'pencil prox', designed for use in the drum counter systems on concrete mixer trucks. It works in conjunction with a magnet mounted on the rotating drum to send a pulse to the in-cab drum counter, allowing the operator to monitor drum speed and total rotations. This sensor is a critical replacement part for maintaining accurate drum count information, which is essential for quality control and operational efficiency. This version features a long lead wire for flexible installation.

Key Features
