Model confirmation
Sleeve thread: M6x0.5 corresponds to 0; 1/4-28UNF-2A corresponds to 1
Armored cable: with corresponding 1, without corresponding 0
Total length of sensor: C=Cx+5.3mm, The value of Cx corresponds to 0 for 25mm, 1 for 30mm, 2 for 40mm, 3 for 50mm, 4 for 60mm, 5 for 70mm, 6 for 80mm, 7 for 90mm, and 8 for 100mm

Adapter plug: with or without
Total cable length: 0 corresponds to 4m, 1 corresponds to 5m, 2 corresponds to 6m, 3 corresponds to 8m, F corresponds to 9m, 4 corresponds to 10m
Cable tail: LEMO or loose wire


Installation and Calibration
Installation: Compact structure, easy to install. The connection between the sensor and the preamplifier can be achieved through LEMO plugs or screw terminals.
Calibration: At the time of delivery, the sensor and preamplifier have been linearly calibrated with 42CrMo4 material at the factory. On site installation usually does not require recalibration, only adjusting the air gap between the sensor and the measuring surface until the desired signal is output from the preamplifier.
