| GKM SERIES (Water Resistance Type) |
| |
PHOTO SENSORS WITH BUILT-IN AMPLIFIER |
| |
 |
| |
| |
Withstands Detergent and Disinfectant Spray |
| |
- We used SUS316L for the case and the best material for all parts to make the GKM suitable for the cleaning conditions of food-processing machinery.
|
| |
Superior Protective Structure |
| |
- The IP69K* (DIN 40050-9) protective structure for a square metal photoelectric sensor. Suitable for high-temperature, high-pressure jet water spray cleaning applications.
|
| |
Shape and Markings Designed for Greater Hygiene |
| |
- Few indentations in the shape means less dust and water can collect, making the GKM more hygienic. No labels have been used in order to prevent foreign matter contaminating food products. The GKM model and lot numbers are imprinted using a laser marker.
