Based on the part number **M2AC-A36-R/CE**, this component is a specific configuration of a **Solenoid-Interlocked Safety Switch**, typically manufactured by brands like **IDEM Safety** or similar industrial automation providers. These devices are used to ensure machine guard doors remain locked until a safe state is reached. --- ## Technical Specifications & Electronic Components The breakdown of the electronic and mechanical parts is as follows: ### 1. Core Component Overview | Feature | Description | | :--- | :--- | | **Device Type** | Solenoid Guard Locking Switch | | **Housing Material** | Die-Cast Metal (typically for 'M' series) | | **Locking Type** | Power-to-Unlock (Spring Lock) or Power-to-Lock | | **Safety Contacts** | Typically 3NC (Normally Closed) safety circuits | | **Auxiliary Contacts** | 1NO (Normally Open) for status monitoring | ### 2. Electronic Interface * **Solenoid Voltage:** Usually 24V DC or 110V/230V AC (indicated by the 'AC' in the string). The solenoid is the electromagnetic coil that moves the internal bolt to lock or unlock the actuator. * **Switching Elements:** Contains positive-break force contacts. These are physical contacts that are forced open by the entry/exit of the actuator to ensure high-reliability safety signals. * **LED Diagnostics:** Most versions include integrated LEDs to show the status of the lock (Locked/Unlocked) and the state of the safety circuit. ### 3. Key Features of the "M2AC" Series 1. **High Holding Force:** Designed to hold doors shut with forces often exceeding 2000N to 3000N. 2. **Redundancy:** The internal electronic layout allows for dual-channel wiring to reach **ISO 13849-1 (PLe)** and **SIL3** safety ratings. 3. **Manual Override:** Often features a manual release key (the "R" in the part number often indicates a manual release function) for emergency use during power failures. --- ## Wiring Logic (Typical) | Pin/Terminal | Function | Purpose | | :--- | :--- | :--- | | **A1 / A2** | Solenoid Power | Energizes the internal coil to actuate the lock. | | **11/12 & 21/22** | Safety Contacts | Wired into the safety relay to stop the machine if the door is opened. | | **33/34** | Auxiliary Contact | Used for PLC signaling (non-safety). | --- ## Safety Standards (CE Marking) The **/CE** suffix confirms the part complies with European safety directives: * **EN 60947-5-1:** Low-voltage switchgear. * **ISO 14119:** Interlocking devices associated with guards. * **ISO 13849-1:** Safety-related parts of control systems.
