Bimba Two-Wire Solid State Reed Switches Operating instructions

  • Hello! I've reviewed the product instructions for the Bimba Two-Wire Solid State Reed Switch, including models MDFQ, MDF, and MDFX, and their 90 degree variations. This document provides details on mounting, electrical specifications, and wiring instructions. I understand the importance of connecting the correct wires specifically for the MDFQ quick connect model and the torque limits for mounting. I'm ready to assist with your questions.
  • What is the maximum torque on the set screw?
    What is the input voltage range for the switch?
    What is the maximum current rating for the switch?
    What is the enclosure protection rating?

On Quick Connect switch models, connect
only the Blue and Brown wires on the mating
cable and cut back the Black wire. Do not
connect switch to a mating cable that has been
previously wired for a three-wire solid state
switch as it will short the MDFQ switch.
