The S12R-SSRDSO-NCSL5-001 Hall Effect Gear Tooth Speed Switch is a “zero speed” indicator that detects rotational or linear over or under speed conditions. The S12R-SSRDSO-NCSL5-001 is a normally closed Form B Relay actuated by steel gears or other ferrous targets. The targets’ speed is resolved using a single channel digital square wave relay output. S12R-SSRDSO-NCSL5-001 Speed Switches are programmed to switch at 1 Hz. In other words, 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 relay opens. An open relay output means that an over-speed condition has occurred. Conversely, the relay closes when the gear “teeth” are moving slower than 1 tooth per second, indicating a “zero speed” condition.
The S12R-SSRDSO-NCSL5-001 Speed Switch has a 150 VAC normally closed Relay output powered at 8 to 32 VDC. This sensor is potted in an M12 stainless barrel housing with a shielded 2 pair 22 AWG PVC cable.
“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
