Load Button with Threaded/Tapped Holes

Compact, diverse and durable
Description
Model LLB400 is a Load Button Load Cell with Threaded Mounting Holes built for Press, or Inline compression applications. The standard LLB400 Load Button Load Cell model has a very robust construction available in 17-4 Stainless Steel, with a 1.25” outside diameter and a 10 feet long 26 AWG 4 conductor shielded Teflon cable. You will also find options for external matched output readily available.
The Load Button Load Cell offers high accuracy. It has Nonlinearity of ±0.5% and Deflection of 0.0009” to 0.0015” nominal. The standard LLB400 Load Button Load Cell can be modified or customized to meet your requirements and most capacities are in our inventory, making them available for 24 hour shipping.
Product Highlights And Features
- Ultra low deflection
- Robust strain relief
- 17-4 PH stainless-steel construction
- For use in compression
- Utilizes metal foil strain gauge technology
- Adheres to RoHS directive 2015/863/EU
With a package that stands at 1.23in (31.2mm) in diameter and 0.39in (9.9mm) in height, the LLB400 Low Profile Load Button Load Cell is an extraordinarily accurate miniature sensor that punches well above its size with a capacity range from 100 to 2500lb (45.3 to 1134kg). This diverse and durable sensor solution features three mounting holes built for press or inline compression applications, such as measuring loads on a turbine shaft or gauging forces on a CNC workpiece.
The LLB400 is now offered with an integrated connector that makes it fully IP67-rated for high water resistance and temporary submersibility. The connectorized 4-position micro receptacle allows you to easily remove the wire from the sensor like a plug from a socket. This new feature protects the sensor from cable damage, as you can easily replace a faulty wire.
The LLB400 is also available in the original design, which features a cable connection with a 10-foot (3.048m) long 28 AWG 4 conductor shielded cable.
Wide range and flexibility
LLB400 series offers button load cells in six capacity options that measure compressive loads from 100 to 2500lb (45.3 to 1134kg), a remarkable range for such a tiny package. Three threaded holes allows the part to be securely mounted from the bottom.

Robust construction
The seam-welded stainless steel body provides outstanding strength and corrosion resistance and provides enhanced protection against physical damage in addition to withstanding other harsh environmental conditions. A special heat treatment process has been applied to the flexure to improve durability, extending the life-cycle of the sensor.
Best-in-class material
The exceptional quality of this sensor makes it highly durable and reliable. Its body is made of aerospace-grade 17-4 precipitation hardened stainless steel, which provides high strength, high hardness, and corrosion resistance over a wide temperature range.

Eliminating moisture
The robust assembly of the 4-position micro receptacle version eliminates moisture ingress through the connection location. With an IP67 rating, the product can withstand submersion in one meter of water for a minimum of 30 minutes. This opens up more options for applications as it will allow outdoor usage in wet, rainy, or highly humid conditions.

Plug in, plug out
The newer version of this series — including the entire 100 to 2500 lb capacity range — feature the 4-position micro receptacle. This gives the load cell greater flexibility and durability, as a damaged or cut cable can now easily be replaced, saving the user time and resources. It also simplifies the installation process, reducing installation time and maximizing up time.
The 4-position micro cable connector is shown here on another sensor model.
Made to be accurate
The LLB400 has a nonlinearity of ±0.5% and deflection of 0.0009 to 0.0015in nom. In addition, special design and manufacturing touches further enhance the sensor’s performance, such as a highly customized strain element that greatly reduces solder joints, increasing the sensor’s reliability.
Designed for precision
The spherical radius of the load button has been designed to maintain the highest possible level of accuracy. By minimizing contact with the loading provisions, the button’s spherical shape transfers the load evenly over the sensing area, compensating for potential misalignments.
Low power-consumption
With a 740 bridge resistance, the LLB400 draws less than 0.035W with a 5 VDC excitation, which is around 50% less current than a traditional load cell. This is especially valuable for any applications that are battery operated or are embedded in tight spaces where heat generation could become an issue.
High natural frequency
The LLB400 delivers a remarkably high natural frequency (starting at 14kHz and going up to 45kHz), providing a fast response time that benefits accuracy and cycle time reduction, especially in dynamic applications.
Calibration included
The LLB400 has been tested by FUTEK’s world-class calibration department and is NIST traceable. We can also reduce hidden costs and setup time by calibrating your sensor with FUTEK electronics of your choice. In addition, we offer calibration to ANSI Z540-1 and ISO 17025 standards upon request.
