The S12R-SSRDSO-NOSL5-500 Hall Effect Gear Tooth Speed Switch detects rotational or linear over or under speed conditions. The S12R-SSRDSO-NOSL5-500 is a normally open Form A 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-NOSL5-500 Speed Switches are programmed to switch at 500 Hz. In other word, the sensor detects if more or less than 500 “teeth” are moving per second. When the Speed Switch senses the gear teeth moving faster than 500 teeth per second, the relay closes. A low relay output means that an over-speed condition has occurred. Conversely, the relay opens when the gear “teeth” are moving slower than 1 tooth per second, indicating an “under speed” condition.
The S12R-SSRDSO-NOSL5-500 Speed Switch has a 150 VAC normally open 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.
