Anwendungsszenarien

Kernfunktion

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. Werkzeugmaschinenindustrie (Am häufigsten)
2. Bearbeitungszentren, CNC milling machines & Drehmaschinen: 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. Schleifmaschinen, high-speed saws & punch presses: Two protective covers for high-speed rotating and reciprocating motions, meeting PL e safety requirements.
4. Laser cutting & Plasmaschneidmaschinen: Upper and lower material loading doors; laser emission is only enabled when both doors are fully closed.
5. Automatisierte Produktionslinien & Montageausrüstung
6. Robot workcells (fencing): Two access gates for the robot enclosure; robot stops immediately if a gate opens during operation.
7. Custom assembly machines, hydraulische Pressen & Nietmaschinen: Front maintenance door + side material feed door with interlock logic.
8. Förderer, Transfermaschinen & rotary lifting stations: Service access gate + bypass protection gate.
9. Spritzguss & Druckgussmaschinen: Schimmelschutztür + barrel protective door with lock function to prevent opening during mold clamping and melt processing.
10. Verpackung, Drucken, Lithiumbatterie & 3C Equipment
11. High-speed packaging, laminating & Schneidemaschinen: Two rotary roller guard doors.
12. Li-ion winding machines, Elektrolytfüllmaschinen & formation cabinets: Dual chamber doors to prevent high-voltage hazards and mechanical pinch injuries.
13. SMT-Bestückungsmaschinen, AOI testers & FPC equipment: Front and rear maintenance hatches.

Vorteil: Non-contact design with no mechanical wear, long service life and resistance to dust and oil contamination.

4. Materialhandhabung & Lagerausrüstung
5. Vertical elevators & Aufzüge: Upper and lower level protective doors.
6. Sortiersysteme & Cross-Belt-Sorten: Two fence service doors.
7. Small AGV and tooling trolley cabin hatches.
8. Essen & Pharmazeutische Maschinen (Cleanroom Use)
9. Abfüllmaschinen, bottle washers & Siegelmaschinen: Dual clean chamber doors.
10. Sterilization equipment: Chamber door + service door. Non-contact design avoids jamming and is easy to clean with no mechanical friction.

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

6. Test Benches & 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.

Leitfaden zur Modellauswahl (Kritisch)

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 Sicherheitstore.

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)

Ungeeignete Anwendungen

Mehr als 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)
