The HoldXR magnetic solenoid interlock from SSP Safety System Products combines a safe non-contact RFID safety sensor (Ple) with an intelligent electromagnet. It is available with 500 N or 1200 N, depending on the design. Up to 17 solenoid interlocks can be connected in series via incoming and outgoing pigtail cables. For this purpose, the cable is looped through, thus reducing the amount of cabling required. Each individual unit can be evaluated and controlled separately via an internal bus, which can be evaluated without a gateway to the higher-level PLC. A Bluetooth interface enables the user to access the guard locking's diagnostic function via a mobile app and view the error memory, for example. The RFID safety sensor is also available in a highly coded version.
