Tongue-type safety limit switches are used for monitoring the mechanical guards and doors of machines. They are suitable for machines that stop quickly after a stop command is issued. When the guard/door is opened, the machine must stop faster than the time it takes to reach the machine’s hazardous moving parts. For new machines, it is essential to consider the coding and installation requirements specified in the EN ISO 14119 standard. Therefore, we recommend using coded, contactless RFID sensors for new machines to ensure enhanced safety and compliance.
Pizzato FD/FL series safety limit switches are robust, metal-bodied switches available in nine different contact configurations. The basic model includes an M20 cable entry, with additional models available with M12 connector versions. The operating temperature for the standard model is -25…+80 °C, with an extended range version (-T6) available for -40…+80 °C.
Features:
The Pizzato FR/FX series safety limit switches are cost-effective, plastic-bodied safety switches available in fifteen different contact configurations. The basic model features an M20 cable entry, with additional models available in M12 connector versions.
Features:
The use of non-contact safety limit switches is continuously increasing due to their enhanced safety and resistance to tampering. Traditional applications for non-contact safety switches include breweries, dairies, food, and pharmaceutical industries, where hygiene requirements are exceptionally high. Another area where non-contact sensors are ideal is environments with dust, stone particles, or other materials that can eventually damage traditional tongue-type limit switches. These environments include sawmills, planing mills, and other wood processing areas.
The ST Series RFID sensors come in three models: the basic ST D, the compact ST G, and the magnetically-held ST H.
