Description
The LKGA is a load cell for 50, 100 or 200 kN with built-in CANopen electronics: the measured value is sent digitally over the bus, as a TPDO and as a safety-related SRDO to CiA 304. The stainless steel body is protected to IP67. The load is applied through a load button Ø 32 mm with spherical radius SR 160; the cell is fixed with six M6 threads on the Ø 72.5 mm pitch circle. Supply and bus run through an M12 × 1, 5-pin device connector. The SRDO sends every measured value twice, the second frame bitwise inverted; node ID and baud rate are set via SDO.
