Selection & installation notes
- The naming image describes 3-wire and 4-wire options; the selection chart above lists -3 models. Confirm wiring before using a two-wire sensor mentioned in the introduction.
- C denotes the MIL connector option for 16/32-point variants. The 32-point family uses MIL output; verify the exact pin map and whether each terminal specification applies to the selected connector.
- The 3 A peak value is not a continuous rating. Confirm current per signal, sensor supply total and common-path limit; terminal wire capacity does not raise the module rating.
- This is a wiring interface; no input-to-output galvanic isolation is established by its dielectric test. Status LEDs do not prove correct sensor operation.
- De-energize before plugging, changing NPN/PNP selection or wiring. Match power polarity and unused pins to the exact production schematic.
