The S18-SSTHS1-R5SA5-30 Hall Effect Magnet Speed Switch detects rotational or linear over or under speed conditions. Operating at 55 Gauss sensitivity, the S18-SSTHS1-R5SA5-30 is actuated by a south pole moving magnet. The Speed Switch turns on when the transistor output goes low. The programmed switching frequency is 30 Hz. So, a low output means that an over-speed condition has occurred. Conversely, the switch turns off when the output goes high, indicating an under-speed state.
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.
Other features include:
- Non-contact speed measurement
- No orientation required
- Add –xxx in Hz to End of PN –contact factory for custom switch point models
