The screw thread is of the tap size no. 6, with 32 thread-per-inch, under the Unified National Coarse definition (6-32 UNC ISO68-2 ISO263). The cables are multi-stranded copper AWG#28, UL 3656 certified, with XLPE insulation, and a rating of 125 °C and 300 V. ## **MOUNTING** Inserted in a threaded hole (for example tapping #36 / 2.85 mm) or in a clearance hole (for example clearance drill #25 / 3.80 mm). The product is not intended to be mounted in direct contact with water or liquids. The recommended torque is 0.89 N · m / 7.9 inch-pounds. Leads conductors can be soldered or crimped. ## **DIMENSIONS** in millimeters ~~Ce~~ ||||D|||||||||||||| |---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---| |||||||||||||||||| |||||||4.||2.|||||3.|||| |||||||L2||||1.||||C||| ||||||||L1||||B|||||| |||||||||||||||||| ||**L1**||**L2**||||**B**||**C**|||||||**D**| |200 +10 / -15|200 +10 / -15|200 +10 / -15|2.5 ± 1||||12.70 ± 1||6.35 ± 1|6.35 ± 1||||||6.35 ± 1| ## **Notes** 1.
