FAQs: Precision Sensors for Robotics Applications

Precision robotic sensor components include machined housings, mounting brackets, and interfaces for feedback detection devices in robotic systems. These components comprise force-torque sensor bodies that measure multi-axis loads of up to 5000 Newtons, encoder mounting brackets that position optical or magnetic encoders with sub-degree accuracy, tactile sensor arrays with spaced sensing elements, adjustable mounts for vision system cameras, protective housings for laser distance sensors, proximity brackets with 0.1 millimeter repeating positioning, and IMU (inertial measurement unit) enclosures.

Aluminum offers lightweight housings, along with high heat dissipation and thermal conductivity, a low thermal expansion coefficient, and easy machinability for complex geometries. Stainless steel offers high structural rigidity for force sensors, non-magnetic properties for magnetic encoders preventing interference and high corrosion resistance. Titanium has an exceptional strength-to-weight ratio, low thermal expansion for precision measurements and high corrosion resistance. Machinability, for small precision components and for electromagnetic shielding, is another reason brass is used.

Multi-axis CNC milling creates complex 3D housings with integrated mounting features and cable routing channels. Precision turning machines cylindrical sensor bodies and shaft interfaces with concentricity within 0.0005 inches. Surface grinding achieves flatness below 0.0003 inches on mounting surfaces for accurate sensor positioning. Coordinate drilling produces mounting hole patterns with position accuracy within ±0.003 inches. Seal grove machining creates O-ring grooves for environmental protection. Thread milling produces precision threads for sensor installation and cable gland connections.

For the machining tolerances, we are able to maintain mounting surface flatness to 0.0003 inches for precision sensor placement and concentricity to 0.0005 inches for concentric rotating sensor shafts. Mounting hole positions are achieved to ±0.003 inches for repeatability and seal groove dimensions to the precise ±0.002 inches for IP65/IP67 environmental sealing. Overall housing dimensions are ±0.005 inches for consistent performance and accuracy in sensor output.

Yes. We offer flexible manufacturing capabilities including:
Rapid prototyping for design validation
Low-volume production for specialized applications
High-volume production with consistent quality control
Full structural and dimensional verification at every stage

Yes, all components are manufactured in compliance with the ISO 9001 quality management systems with complete traceability of materials, dimensional checking of sensor housings and mounting components in industrial robotics which require dependable position feedback, force measurement and environmental sensing, and advanced motion control and safety applications.

We provide comprehensive finishing solutions tailored to aerospace requirements:
Anodizing (Type II and Type III)
Passivation for corrosion resistance
Precision polishing for aerodynamic surfaces
Custom protective coatings and thermal barriers

Standard sensor housings and brackets need 8–12 business days, while complex multi-feature assemblies with tight tolerances take 3–4 weeks, which includes precision grinding and surface treatment. To support rapid sensor integration and testing validation, prototype runs can be completed in 5–8 days.

Design efforts focus on lightweight sensor housings for collaborative robot force sensing to minimize inertia, thermally stable housings for high-precision measurement with dimensional stability within 1 micron across a 50°C range, sealed enclosures with IP67 protection for wet manufacturing environments, miniaturized housings for compact robot joints with space constraints, and integrated multi-sensor housings that combine force, position, and proximity sensing in unified assemblies.

Flatness of accurate mounting surfaces to within 0.0003 inches results in repeatable sensor placement which retains calibration accuracy to within 0.1 percent full scale. Concentricity for rotating sensors to within 0.0005 inches eliminates runout in position measurement. Material and design selection to control thermal expansion results in accuracy maintenance of the sensor within industrial temperature ranges of minus 20 to plus 80 degrees Celsius. Strategic placement of the mounting holes permits the required sensor alignment for multi-axis force measurement with crosstalk under 2 percent. Effective sealing of the electronics preserves the signal from loss due to moisture and airborne contaminants. Rigid construction of sensor housings preserves deflection under load, ensuring measurement accuracy and repeatability of force-torque sensors within 0.5 percent.
