The 1KN series safety light curtain complies with international safety standards IEC61496-1 and IEC61496-2 TYPE 2. It has obtained a certificate of conformity from a well-known European certification body and also meets the domestic TS certification requirements.
Due to the limited space in factory environments, machines are often placed side by side with minimal distance between them. This highlights the inherent susceptibility of infrared systems to interference. To address this, the 1KN series effectively reduces cross-interference between light curtains through optimized frequency settings and infrared sensor hardware configuration.
Available with 30mm and 40mm object detection resolutions for customer selection.
30mm resolution: sensing range 0.5 ~ 5m.
40mm resolution: sensing range 4 ~ 10m.
IP65 waterproof and dustproof rating.
Equipped with self-diagnosis and operation status indicators.
Specially designed to prevent mutual interference between light curtains.
High vibration resistance technology adopted for punching and shearing equipment.
