POSITAL has introduced a new spring-loaded pivot arm mounting system for wheel-encoder assemblies. Like earlier spring-loaded mounting brackets, this device is designed to minimize slippage by maintaining a steady contact pressure between the wheel and the moving surface. However, the pivot arm can accommodate larger lateral movements of the moving surface. Spring tension can be […]

Encoders are central to motion control applications, providing feedback in order to increase system accuracy and reliability. As other components in motion systems evolve, encoder manufacturers are making sure that their offerings keep pace with these broader technological changes. For instance, the rise in high-performance networks for motion control is in part driven by the […]

POSITAL’s new 22-mm multiturn kit encoders are high-precision multiturn absolute position feedback devices for miniature motors and drives. While motion feedback devices for small motors have previously been limited to single-turn or incremental encoders, the new compact kit encoders from POSITAL now provide full multiturn measurement capabilities – without any need for backup batteries. The […]

Feedback-equipped stepper motors are not a complete substitute for servomotors, but they can provide a reliable alternative for many real-world applications. These motion-design solutions improve machine performance without breaking the bank. By Jim Stevens • Product Specialist | POSITAL Inc. Stepper motors are a top choice for many motion and position control applications. They’re available […]

Wiegand sensors are tiny devices that use variations in an external magnetic field to generate electrical signals and energy. They have unique properties that make them a useful option for many proximity sensing systems. Wiegand sensors are built around small sections of Wiegand wire, a specially prepared ferromagnetic alloy that has a unique physical property. […]

Sensor manufacturer POSITAL has released its intuitive online tool Encoder.Match.com. This new web platform, which combines a search engine, product configurator and ordering tool, is aimed at the MRO/spare parts business. With a few mouse clicks, maintenance staff and technical buyers can quickly find cost-effective replacements for encoders in existing machines or systems – regardless […]

POSITAL has expanded its range of absolute rotary encoders and inclinometers to include support for the common Modbus RTU communications interface. Modbus RTU is a low-cost, easy-to-implement communications protocol that’s commonly used in small to mid-sized control systems (up to 32 nodes). Available for almost four decades, it’s supported by many PLC manufacturers and has […]

Sensor manufacturer POSITAL has introduced an inexpensive and flexible alternative for safety-critical motion control systems. Supplementing its existing range of formally certified SIL safety encoders, the new ‘diverse-redundant absolute encoders’, based on non-certified standard components, are a suitable choice for many installations where functional safety is required. When combined with functional safety PLCs, these devices […]

POSITAL has expanded its portfolio of rotary encoders and inclinometers (tilt sensors) to include more devices with IP69K level environmental protection. These sensors, which are designed to stand up to repeated exposure to the hot, high-temperature water jets used in pressure washing systems, are now available with a wider range of mechanical options and communications […]

POSITAL has announced that its family of absolute IXARC rotary encoders has been expanded to include support for the popular IO-Link communications interface. IO-Link is a low-cost, easy-to-implement communications system designed to simplify connections between large-scale fieldbus or industrial Ethernet networks and sensor or actuator devices located on the factory floor. On one side of […]

Cube encoders – incremental rotary encoders with a cube-shaped housing – have been popular with machine builders since the 1960s, largely because these devices are easy to install without special mounts or brackets. Now POSITAL has updated this old favorite with new features and capabilities that will keep this design relevant for years to come. […]

While servomotors remain the gold standard for precision motion control in industrial machinery, the improved performance of stepper motors is making these lower-cost devices an increasingly attractive alternative for many applications.
