Description
The SICK F39-LJB3-M6 is a heavy-duty mounting bracket accessory designed specifically for SICK deTec / deTec4 / miniTwin / S300/S330/S340 safety light curtains and safety laser scanners. This bracket features an M6 fixing thread/bolt interface and provides stable, vibration-resistant support for precise alignment of the protective field. It is typically used in pairs (one for the emitter, one for the receiver/scanner) and allows fine angular adjustment to ensure optimal muting and detection performance in demanding industrial environments.
