Bimba Mini Reed Switch Assembly Instructions

  • Hello! I've reviewed the Product Instructions for the Bimba Mini Reed Switches, including models MRQ-90, MRQC-90, MRQCX-90, MR-90, and MRX-90. This document provides essential information on mounting, electrical specifications, and pin assignments for these switches. I’m ready to answer any questions you might have about these devices.
  • What is the maximum torque on the set screw?
    What is the switch voltage?
    What is the maximum current?

ELECTRICAL SPECIFICATIONS
PIN AND WIRE ASSIGNMENTS
MRQ, MRQC, MRQCX
8 mm Female Connector
Face View of “Q” Option Male Connector
MR, MRX
Model “C” - 2 m Cable
Model “CX” - 5 m Cable
PIN 1 − BROWN − POSITIVE
PIN 3 − BLUE − NEGATIVE / NEUTRAL
PIN 4 − BLACK − OUTPUT
(NOT USED FOR TWO WIRE SWITCHES)
1. POSITIVE / HOT
3. NEGATIVE / NEUTRAL
4. OUTPUT

FOR 2 WIRE SWITCH
MODELS
Note: Always connect the switch in accordance
with the diagram above. If leads are reversed,
the switch will operate, but the LED (single
direction LED) will not.
On Quick Connect reed 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 MRQ switch.
