Narrow Pulser Wraps

Narrow Pulser Wraps

Narrow Pulser Wraps are PVC, aluminum, or stainless steel split collars with magnets mounted on the outside circumference. The magnets serve as targets for Hall Effect, and Magneto Resistive sensors that switch when exposed to magnetic fields.

All wraps are custom machined to the diameter of the monitored shaft, and are split into halves. This splitting process allows the wrap to clamp tightly onto the shaft without tearing down any equipment to install them. The halves are secured around the shaft with recessed Allen head socket screws (supplied). Standard pulser wraps provide magnetic targets that are strong enough to allow gap distances up to 1/2 inch when used with an Electro-Sensors Hall Effect sensor. The wrap and sensor system forgives slight misalignment of the sensor, machinery vibration, dirty, wet, or greasy environments, and shaft end play.

Narrow Wraps are 0.625″ wide and have a minimum outside diameter of 7″.
