The Bimba MRS® Magnetic Reed Switch is a versatile sensing device available in various configurations, designed for reliable operation in industrial applications. This document provides assembly instructions, switch mounting guidelines, pin and wire assignments, and detailed electrical specifications for several models.

Function Description:

The MRS® Magnetic Reed Switch operates as a proximity sensor, detecting the presence of a magnetic field, typically generated by a magnet embedded in a pneumatic cylinder piston. When a magnet approaches the switch, the reed contacts inside the switch close, completing an electrical circuit. This allows for position sensing, automation, and control in various machinery. The switches are designed for easy mounting on pneumatic cylinders using a U-shaped bracket and a button head hex screw, ensuring secure and precise positioning.

Usage Features:

Mounting: The switches are designed for easy and secure mounting using a U-shaped bracket and a button head hex screw. The mounting instructions illustrate how to position the switch on a cylinder, tighten the screw, and adjust its position for optimal sensing.
Connection Options: Available with either pig tail leads for direct wiring or quick connect (8mm male connector) for faster installation and replacement.
Cable Options for Quick Connect Models: For quick connect models, 2m (Model "C") and 5m (Model "CX") cables with 8mm female connectors are available separately.
Pin and Wire Assignments (Quick Connect):
- 8mm Female Connector:
  - Pin 1: Brown - Positive
  - Pin 3: Blue - Negative / Neutral
  - Pin 4: Black - Output (Not used for two-wire switches)
- Face View of Male Connector:
  - 1: Positive / Hot
  - 3: Negative / Neutral
  - 4: Output (Not connected for two-wire switch models)
