Product Overview
W4S1-05B belongs to Omron W4S safety light curtain family used for safeguarding access points and hazardous machine areas. Light curtain systems are deployed where non-contact detection is required to trigger protective stop or inhibit hazardous motion when a person or object enters the protected field. A 5-beam configuration is typically considered for presence detection use cases where application risk assessment and required protective performance level define final architecture. During project implementation, teams should confirm mounting distance, beam alignment, response behavior, muting strategy where applicable, and safety relay/controller integration. Compliance work must include risk assessment, validation testing, and documentation aligned with applicable machine safety standards and site requirements. W4S1-05B is generally selected for compact guarding tasks where reliable optical field interruption monitoring is needed in production equipment.
