SICK M40S-64A303AA0 Safety Light Curtain System

SICK M40S-64A303AA0 is a M4000 Advanced Curtain safety light curtain emitter (sender) designed to pair with a compatible receiver to form a guarded zone around hazardous machinery. The system specifies a protective field height of 900 mm, a maximum sensing distance of 21 m, and a 30 mm resolution, making it suitable for mid-to-long reach safeguarding on automated lines. It operates from 24 V DC and uses a Hirschmann M26 12-pin connector for interface to safety electronics. The model is designated as the Sender in the M40S-64A303AA0 configuration and can be configured via software with a matching receiver/controller. Safety performance is rated PL e and SIL 3, aligning with contemporary machine safety standards. Common applications include guarding conveyors, presses, and other automated material-handling equipment where fast beam interruption is required to stop machinery and protect personnel. When paired with a compatible receiver and safety controller, beam interruptions trigger a controlled shutdown of the guarded equipment in accordance with the safety architecture described by SICK’s M4000 Advanced Curtain family.
