Scenari applicativi

Caratteristica principale

One evaluation unit monitors 2 safety gates/protection points simultaneously. The Unicode exclusive coding prevents bypass and replacement, ideal for high tamper-proof requirements. It works with non-locking CES read heads and locking CEM/CET safety interlocks (IN 1088).

1. Industria delle macchine utensili (Più comune)
2. Centri di lavoro, CNC milling machines & torni: Dual front + side safety doors. Immediate safe stop once any door opens. Paired with CET locking read heads to keep doors locked until spindle coasts to rest.
3. Rettificatrici, high-speed saws & punzonatrici: Two protective covers for high-speed rotating and reciprocating motions, meeting PL e safety requirements.
4. Laser cutting & macchine per il taglio al plasma: Upper and lower material loading doors; laser emission is only enabled when both doors are fully closed.
5. Linee di produzione automatizzate & Assembly Equipment
6. Robot workcells (fencing): Two access gates for the robot enclosure; robot stops immediately if a gate opens during operation.
7. Custom assembly machines, hydraulic presses & macchine rivettatrici: Front maintenance door + side material feed door with interlock logic.
8. Trasportatori, macchine transfer & rotary lifting stations: Service access gate + bypass protection gate.
9. Stampaggio ad iniezione & die-casting machines: Porta antimuffa + barrel protective door with lock function to prevent opening during mold clamping and melt processing.

Nota: Select stainless steel food-grade read heads for this application.

6. Banchi prova & Laboratory Tooling
7. High-voltage test stands & aging cabinets: Two safety hatches; Unicode coding prevents personnel from shorting safety circuits to access hazardous areas.
8. Impact and durability test rigs: Dual protective enclosure doors.

Guida alla selezione del modello (Critico)

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 cancelli di sicurezza.

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; IN 1088)

Applicazioni non idonee

Più di 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)
