Laboratory Resistor Applications

The Laboratory Resistor – Invaluable In Many Applications
The laboratory resistor (also referred to a a slider resistor) has been used for a convenient way to achieve and easily adjustable power resistance for over 50 years. Whereas a wire wound potentiometer offers a variable power resistor via a rotary form of adjustment, the laboratory resistor offers a way of adjusting the resistance via a linear form of resistance.

Many educational institutions such as universities, technical colleges and high schools use laboratory resistors in their electrical and electronics courses as they allow students to easily and accurately set a specific resistance value via the sliding […]

Panel Mount Resistors

The addition of aluminium housed resistors to our range of resistors means that our customers have an increased option when it comes to resistor selection for their application.

Terminology: Panel mount resistors are also referred to in the electronics industry as ‘panel mount resistors’ and ‘aluminium housed resistors’.

Applications; This style of wire wound resistor is used where a small physical size is required (relative to the power rating of the resistor) and a rugged construction of the resistor is required.

Mounting And Heat Sinking: The aluminium housed resistors are typically mounted on a suitable heat sink material by way of the mounting […]

Current Sense Resistor Application

Current Sense Resistor Case Study – Motor Control Application
Case study: Motor Control Feedback

A client manufacturing motorised garage door controllers had a pcb based micro controller circuit which required a determination of:

current flow through the garage door drive motor
overload of the drive motor, in instances where the garage door jammed or failed to move for some reason, indicating a fault. The micro controller then needed to receive this signal and then via a p.c.b. mounted relay, cut off the drive motor, avoiding damage to the motor and possible damage to the drive chain of the door opener.

Being a pcb mount design, the […]

AW Series Wire Wound Potentiometer – Oven Control Application

Our resistors products have been used in literally thousands applications for over 30 years. Over the next few months we will discuss some of the end products that the resistors went into. In some instances ‘standard’ products were used, however, in many instances we have offered our clients a highly customised resistor that exactly meets their requirements and specifications:
AW Potentiometer For Oven Temperature Control Application.
One of Australia’s most high profile manufacturers of stoves, ovens and range hoods approached us as they had a new ‘high end’ range in design but needed a high quality wire wound potentiometer to work in […]
