Why Choose the IMO B5KN3 Three-Position Rotary Selector?
The IMO B5KN3 is a robust and dependable three-position rotary selector actuator designed for industrial control panels, machinery interfaces and operator stations. As part of the established IMO B5 30 mm control-device range, it provides clear manual selection between three maintained operating positions.
This non-illuminated selector features a black rotary knob, an aluminium-finish front ring and 60° switching movement. Its maintained action keeps the selector in the chosen position after the operator releases the knob, making it suitable for selecting operating modes, machine functions and control states.
Designed for installation through a 30.5 mm panel aperture, the B5KN3 has an IP65 front protection rating and accepts compatible IMO connector and contact-block components. Its modular construction enables the required electrical contact arrangement to be selected separately for the application.
Key Advantages
- Industrial three-position rotary selector actuator for machinery controls.
- Maintained operation holds the selected control position.
- 60° switching movement provides distinct position selection.
- IP65 front protection suits demanding panel environments.
- Black rotary knob provides straightforward manual operation.
- Modular design supports compatible IMO contact-block configurations.
Key Features
- IMO B5 control and signalling range.
- Three maintained selector positions.
- 60° operating angle.
- 30.5 mm panel mounting aperture.
- Black, non-illuminated rotary knob.
- Aluminium-finish front ring.
- IP65 front protection rating.
- Compatible contact blocks and connector components available separately.
Reliable Mode Selection for Industrial Machinery
Rotary selector actuators allow an operator to choose between defined machine functions or control states. Turning the IMO B5KN3 moves the compatible contact-block mechanism between three positions, enabling commands such as manual, off and automatic operation to be implemented within the control circuit.
The maintained mechanism remains in the selected position until it is deliberately turned again. Combined with its IP65-rated front and modular contact-block arrangement, this makes the B5KN3 a practical operator-control component for industrial panels and machinery exposed to dust or water jets.
Typical Applications
- Manual-off-automatic mode selection.
- Industrial machinery control panels.
- Operator stations and control consoles.
- Production and process-control equipment.
- Pump, fan and conveyor controls.
- Electrical cabinets and automation systems.

Frequently Asked Questions
What is the IMO B5KN3 used for?
The B5KN3 is used to select between three operating modes or control states in industrial machinery and automation systems.
Does the B5KN3 have maintained or spring-return operation?
The B5KN3 has maintained operation, so the knob remains in the selected position after it is released.
What panel aperture is required for the IMO B5KN3?
The selector actuator is designed for installation in a 30.5 mm mounting hole.
What protection rating does the B5KN3 provide?
The front of the installed actuator has an IP65 protection rating, providing protection against dust and water jets.
Are electrical contacts included with the IMO B5KN3?
The B5KN3 is a modular selector actuator; compatible IMO connector and contact-block components are selected separately to create the required electrical contact arrangement.
Trusted for Industrial Operator Controls
IMO push-button and selector components are used by panel builders, automation engineers and machinery manufacturers to create clear, durable and dependable operator interfaces for industrial equipment.
