The diagrams show the external dimensions of
the 4 Form C and 4-pole bifurcated (twin) types.
For 1 Form C, 2 Form C, and 3 Form C, see
diagrams at plug-in types (only the terminals are
different).
Types with 0.9 mm terminal width are also
available.

Notes: 1. In mounting, use M3 screws and M3 washers.
2. When mounting TM types, use washers to prevent damage or distortion to the polycarbonate cover.
3. When tightening fixing screws, the optimum torque range should be 0.294 to 0.49 N·m, (3 to 5 kgf·cm).
Moreover, use washers to prevent loosening.
