CE, cULus approval, TÜV, FCC, IC. The standard EN60947-5-3 is only met when the entire system, consisting of a safety switch (PSENcode), actuator (PSENcode), and safety monitoring module (PNOZ X or PNOZmulti), is used. EN954-1 (Cat 4), EN60204-1, EN60947-5-3. Actuator. When the safety barrier is closed, the switch provides 2 normally open semiconductor outputs. Large contactless PSENcode safety switch, fully coded. The safety switch PSEN Cs2.1P is fully coded and only operates with an actuator from the PSEN Cs2.1 series. The actuator must be taught in and can be taught in a maximum of 8 times, but only 1 actuator can be used at the same time. Series connection - You can connect more than 10 safety switches in series according to EN954-1 (Cat 4). The switch responds to a single actuator but can be taught to a new actuator up to 8 times in case of damage. 5 actuation directions, M12 connection, 8-pole.
