Guia de seleção de modelo (Crítico)

CES-AZ-AES-02B (Unicode)

Only recognizes the last taught actuator. Anti-tampering priority. For machines with safety audits and strict anti-bypass requirements.

CES-AZ-UES-02B (Multicode)

Accepts any actuator of the same series. Only used for position monitoring; easier maintenance without re-teaching after actuator replacement.

02B = Max. 2 read heads; choose 04B for 4 portões de segurança.

Recommended Matching Read Heads

CES-A-LNN: Non-locking type, only for door position monitoring

CEM: Process lock for production process protection

CET: Personnel safety lock (door locked until machine stops coasting; EM 1088)

Aplicativos inadequados

Mais do que 2 independent safety doors (select 04B or safety PLC instead)

Multiple gates requiring separate logic and different stop sequences (use a safety controller)

Simple door monitoring without anti-bypass requirements (UES version offers better cost performance)
