Description
Product Name: 440T-MDCLE10CECF Allen Bradley Power module
Product details:
The Allen-Bradley 440T-MDCLE10CECF is a Tongue/Key Operated Safety Interlock Switch from the Trojan T15 range. This device is designed to monitor the position of a guard or gate. It prevents a machine from starting or running if the safety guard is not closed, and keeps the guard locked until the hazardous motion has stopped. The switch uses a positive-mode mechanism to ensure that the safety contacts are opened reliably when the actuator (key/tongue) is withdrawn from the switch head.
- Type: Trojan T15 Safety Interlock Switch, GuardMaster Series.
- Actuation: Tongue/Key Operated.
- Housing: Die-cast metal housing, known for its robustness and suitability for harsh industrial environments.
- Solenoid/Locking Feature: C means it has an Electro-Magnetic Solenoid Lock (Guard Locking). This feature allows the guard to be locked closed until a specific condition (e.g., machine cycle completion, or power removal) is met.
- Operating Head: The letter E often indicates the type of operating head/actuator entry and its rotatability.
2. Product Parameters (产品参数)
| Parameter | Value (Typical/Model Specific) |
| Model Series | 440T-MDCLE10CECF (Trojan T15) |
| Safety Contacts | Typically $\mathbf{2 \times \text{NC}}$ (Normally Closed) – Safety |
| Auxiliary Contacts | Typically $\mathbf{1 \times \text{NO}}$ (Normally Open) – Status/Monitoring |
| Solenoid Voltage (Coil) | C likely indicates 24V AC/DC (Common voltage for control circuits) |
| Actuator Type | Standard Tongue/Key |
| Housing Material | Die-Cast Metal |
| Conduit Entry | CF typically specifies $\mathbf{M20 \times 1.5 \text{ Metric Conduit Entry}}$ |
| Ingress Protection (IP Rating) | Typically $\mathbf{IP67}$ (Dust-tight and protected against temporary immersion in water) |
| Actuator Holding Force | High, characteristic of a robust guard locking switch. |
| Standards Compliance | $\text{EN/ISO 13849-1}$ (Performance Level), $\text{EN 1088/ISO 14119}$ (Interlocking Devices), $\text{IEC/EN 60947-5-1}$ |
Note: Specific contact configurations can vary; $1\times\mathbf{0}$ often means a specific contact arrangement.
3. Product Advantages (产品优势)
- Robustness: The die-cast metal housing provides high durability, making it suitable for heavy-duty industrial applications and harsh environments.
- Guard Locking Safety: The integrated solenoid lock ensures the safety guard remains locked until the machine’s hazardous motion has completely stopped (e.g., run-down time), significantly enhancing operator safety.
- High Reliability: Uses positive opening safety contacts, which guarantee that the contacts will open even if they are welded together.
- Versatile Actuation: The tongue/key operation is highly versatile and suitable for various guard door types (hinged, sliding, lift-off).
- High Holding Force: Capable of withstanding significant forces, preventing unauthorized or accidental opening of the guard.
- IP67 Rating: Provides excellent protection against dust and water, ensuring reliable operation in washing or dusty environments.
4. Precautions (注意事项)
- Correct Wiring: Ensure correct wiring of the safety and auxiliary contacts according to the machine’s safety circuit and schematic. Incorrect wiring can bypass safety functions.
- Actuator Alignment: The key/tongue actuator must be correctly aligned with the switch head to ensure reliable operation and prevent premature wear. Misalignment can cause ‘nuisance tripping’ or failure to actuate.
- Minimum Opening Distance: Do not attempt to bypass the safety function by using a non-standard or spare actuator; the switch is designed to operate safely only when the guard is fully closed.
- Installation Standards: Installation must comply with local safety standards and directives (e.g., ISO 14119 for interlocking devices and ISO 13849-1 for safety-related parts of control systems).
- Guard Locking Integrity: The machine control system must ensure that the solenoid only releases the lock after the hazard has been fully eliminated.
5. Product Application (产品应用)
The 440T-MDCLE10CECF is essential for applications where a guard must remain locked until hazardous motion ceases (guard locking) and where a high level of physical protection (metal housing) is required.
- High Inertia Machines: Used on equipment with a long run-down time, such as large presses, mixing machines, centrifugal machines, and rotating machinery.
- Robotic Cells: Interlocking the entry gates to robotic work cells to prevent personnel access while the robots are in operation.
- Packaging Machinery: Safely securing access points on high-speed packaging lines.
- Heavy Machinery: Any application requiring a robust, tamper-resistant, and high-holding-force interlock switch in harsh environments.
- Processing Plants: Used on access doors for blenders, mills, or agitators in food, beverage, or chemical processing.
