Siemens 7MH7134-2AB30 Milltronics RBSS Return Belt Speed Sensor

The 7MH7134-2AB30 is a Milltronics RBSS (Return Belt Speed Sensor) designed for precise speed monitoring on conveyor belts. This sensor is specifically intended for return belt mounting, where it tracks belt velocity to provide critical feedback to speed-sensing systems. It operates within a range of 2 to 450 rpm and delivers a resolution of 150.4 pulses/m (4.58 pulses/ft), ensuring high accuracy for industrial conveyor applications. The unit features a robust polyester-painted mild steel construction and comes complete with a dedicated mounting kit for streamlined installation.

Installation Guidelines

• Mounting: The RBSS is designed for installation on the return (non-load-carrying) side of the conveyor belt. Use the provided mounting kit to ensure the sensor wheel maintains firm, consistent contact with the underside of the belt.
• Alignment: Ensure the sensor is aligned perpendicular to the belt movement. Proper alignment is crucial to prevent uneven wear on the sensor wheel and to maintain accurate pulse counts.
• Environment: While the polyester-painted mild steel provides durability, ensure the installation area is free from excessive material buildup that could impede the rotation of the sensor wheel.
• Cabling: Use shielded cables for the pulse signal transmission to prevent electrical noise interference, especially if routing near motor power cables or variable frequency drives.
• Maintenance: Periodically inspect the sensor wheel for wear and verify that the rotational resistance remains low to ensure accurate speed reporting throughout the system's operational life.
