Product Description
Industrial Use 306 Stainless Steel Water Leak Detection Sensor
According to the principle of the change of the resistance value of the electrode of the point type water immersion probe, the input signal of the water immersion is amplified, shaped and compared by the special integrated chip, and the dry contact signal is output to indicate whether there is water at the location of the transmitter. It has the characteristics of high reliability, anti-interference, high sensitivity, fast response time and easy installation. Realize power, input and output isolation. It is suitable for communication base stations, power distribution rooms, cable pipelines and other places that need to alarm when there is water.




SW5 water sensor function:
Output an alarm single when there is water length is higher than 2mm.
SW5 water sensor technical parameter:
| rating voltage | AC/ DC 9-36V |
| work current | < 20mA |
| quiescent current | <3 Ma |
| work temperature | -5°C~60°C |
| load capability of relay | (2A @ 250V AC) (2A @ 30V DC) |
| response rate | <50 ms |
| length of wire | 2000mm (or based on requirements) |
| packaging material | epoxy resin |
Connections:
| No. | Color | Definition |
| 1 | Red | Positive pole of DC24V (power in) |
| 2 | Black | Negative pole of DC24V (power in) |
| 3 | Yellow | COM |
| 4 | Green | N.O signal |
| 5 | Blue | N.C signal |
If you want to detect little water (length is not exceed 2mm), can put a sponge block on the floor and put sensor on it, sponge block absorb water, the detect probe can touch the water, sensor output alarm single.
If need more drive current, an outer drive circuit is needed.
