The S12H-SSTDSO-R5CB2-001 Hall Effect Gear Tooth Speed Switch is a “zero speed” indicator that detects rotational or linear over or under speed conditions. The S12H-SSTDSO-R5CB2-001 is actuated by steel gears or other ferrous targets. The targets’ speed is resolved using a single channel digital square wave transistor output. S12H-SSTDSO-R5CB2-001 Speed Switches are programmed to switch at 1 Hz. In other word, the sensor detects if more or less than 1 “tooth” is moving per second. When the Speed Switch senses the gear teeth moving faster than 1 tooth per second, the transistor output goes low. A low transistor output means that an over-speed condition has occurred. Conversely, the switch turns off when the output goes high, indicating a “zero speed” condition.
The S12H-SSTDSO-R5CB2-001 Speed Switch has a regulated input and NPN output with a 5k pull up resistor. This sensor is potted in an M12 stainless barrel housing with an integral 4 pin male 12mm connector.
“SSG” type Speed Switches detect Gear teeth moving past the sensor face, using Hall Effect Technology. In addition to 0-32 pitch gears, speed switches will detect other ferrous targets. Such as, ferrous bolt heads, holes in steel plates, and other magnetic targets.
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:
- Ferrous target speed switch
- No orientation required
- Add –xxx in Hz to End of PN –contact factory for custom switch point models
