No other sensor faces as many different challenges than encoders, which may be subjected to temperatures from -40 or +100°C, to shock, vibration, dirt, or moisture. Many sensors reach their limit particularly when used in mobile machinery, heavy industry, mining or offshore applications. The heavy duty designs from SIKO are ideally suited for positioning tasks in mechanically demanding environments. IP 69K protection rating is achieved throughout the life of the product. Combined with robust ball bearings that are capable of shaft loads up to 270 N, the sensors operate reliably under extreme environmental conditions with aggressive media. Salt spray test has been conducted according to DIN EN ISO 9227 >240h.
