Belt Alignment Sensors And Misalignment Switches
-
Electro-sensors belt alignment sensors are mounted along the conveyor belt that needs to be monitored for misalignment. The rub block assemblies are mounted so that the brass surface area is in-line with the edge of the conveyor belt. When the belt wanders it then rubs up against the brass block. The contact with the belt creates friction and heat that the sensor in the brass block records as a rise in temperature.

Magnet Wheels Pulse Generators
199SM / 198EM Magnet Wheels
-
Magnet wheels work with Electro-Sensors Hall Effect shaft speed sensors providing 120 alternating magnetic poles around the circumference of the 3.75" diameter. The 199SM models mount around shafts up to 3" in diameter and are secured with set screws (provided). The 198EM mounts on the end of a shaft with a 10-32 UNF screw (provided - requires center drilling and tapping the shaft).• Use with 906, 906B, 1101 and other Hall Effect, non-metallic-end-capped shaft speed sensors (consult factory)
