| NK Technologies - AS1 Series, Single-Range AC Current Switch with Dual Outputs |
| |
| AS-DODC Current Switches from NK Technologies provide a product with two individually adustable trip points. The outputs are rated to control up to one amp, up to 30 VDC. The DODC Series is designed to provide two individual output contacts. Currently available in top terminal solid core housing only. The output does not change state upon initial load energization until two seconds have elapsed. After the sensor sees the load for two seconds, then the solid state output will close in 100ms after the current increases over each setpoint. |

Electronic Proof of Flow
- No need for pipe or duct penetrations.
- More reliable than electro-mechanical
pressure or flow switches.
|
Cutting Tools
- Detects when the tool starts to work.
- Detects when the tool cutting surface
begins to dull.
|
Car Wash Machines
Reacts when the brush reaches the surface of the car, and again if the brush hangs up on a mirror |
Interlocking Machines
Allows one machine to start only after two auxiliary devices, such as an exhaust fan and dust collector are operational |
