PMOD RS-485 Torque Screw Value

[kbroad]

For Digilent part number 410-310, PMOD RS-485 card, I'm wondering if you have a specific recommended torque value for the terminal screws. Thanks.

Hi @kbroad,

There is no official torque value set for these screws. It needs to be tight enough for the cable to stay in place during normal use as well as allow for current to flow through the connections.

thank you,

Jon

 Thanks for the quick response, Jon. Any chance you know the thread size of these screws?

I could not locate a BOM for the board on the web. 

A datasheet for what looks to be a similar part from a German manufacturer specifies a torque of .2 Nm.

Another datasheet for a Taiwan manufacturer specifies 2 kgf-cm which also works out to .2 Nm.

That might provide a good starting point.

Hi @kbroad,

I have attached the datasheet for the screw terminals used the Pmod RS485.

Thanks,
