^1 When the actuator is pulled first after unlocked, the holding force increases. ^2 Due to the flexible structure of the actuator, the guard can open 3.8 mm larger than the "Sar". The clearance between the actuator and the main unit may be narrowed by a maximum of 2.3 mm due to the magnet power built into the actuator. ^3 Risk time according to IEC60947-5-3 is 150 ms + 2 ms × (number of cascaded units -1). ^4 When stored for a long period of time, please store it at temperature of 55°C or lower.
