The MT-RE13 series safety switches utilize RFID technology, offering high security and confidentiality (unique coding available), strong anti-interference capabilities, and stability. Alternatively, they can combine multiple magnetically encoded magnetic elements, requiring a specific triggering sequence for proper operation. Non-contact operation provides high misalignment tolerance, a wide detection range, and easy installation. Multiple switches can be connected in series. The MT-RE13-NP/MT-RE13-IO can be used with the MSR-N/P safety module to achieve Level 4 safety, is CE certified, and complies with ISO13849-1 SIL3PLe, Category 4.
