The S18-SSTHS1-R5SA5-30 Speed Switch has a regulated input and NPN output with a 5k pull up resistor. This sensor is potted in an M18 stainless barrel housing with a 4-wire shielded PVC cable.
“SSM” type Speed Switches detect Magnets moving past the sensor face. The operate gap range will be dependent on the material, size, and grad of target magnet. The switching frequency will depend on the number of magnets.
No rotational orientation is required for the sensor to operate. Lock nuts are used to set the air gap within the rage of the sensing target.
