Stepper Motors

Nanotec (Feldkirchen, Germany) introduced the SC3518 series stepper motors that feature high torque and EMC properties. The 2-phase hybrid stepper motors feature frame size NEMA 14 (35 mm) and a 1.8° step angle; torque is between 0.18 and 0.32 Nm. The motors are connected via an integrated connector that enables easy cable adaption. The two outer pins of the connector are attached to the motor housing. Together with the shielded cable, this creates a shield connection with excellent EMC performance. The motors are available with a shaft end for openloop or sensorless control, or with an integrated optical encoder NOE1 with up to 2,000 increments/rotation.

Product of the Month: August 2015

Microchip Technology, Chandler, AZ, offers the PAC1921 high-side current/power sensor with both a digital output and a configurable analog output that can present power, current, or voltage over a single output pin. Power-related output values are also available over the 2-Wire digital bus, which is compatible with I2C™. The sensor, available in a 10-lead 3 x 3-mm VDFN package, was designed with the 2-Wire bus to maximize data and diagnostic reporting, while having the analog output to minimize data latency. The analog output can also be adjusted for use with 3V, 2V, 1.5V, or 1V microcontroller inputs. The sensor is suited for networking, power distribution, power supply, computing, and industrial automation applications that do not allow for latency when performing high-speed power management. A READ/INT pin enables host control of the measurement period, and the pin can be used to synchronize readings of multiple devices. For Free Info Visit http://info.hotims.com/55592-120

Open Frame, XY Linear-Motor Stage

Aerotech’s (Pittsburgh, PA) PlanarDLA integrated, open-frame stages have high dynamics and exceptional geometric performance in a low-profile package. These stages are essential for applications ranging from two-sided LED wafer processing where high-dynamics and micrometer-level straightness are required, to quasi-static optical metrology where high-accuracy and precise geometric performance are necessary.

Compact Range LEDs

Mouser Electronics, Inc. (Mansfield, TX) is now stocking LUXEON CoB Compact Range LEDs from Lumileds (San Jose, CA). These LEDs offer high flux densities in a very small light emitting surface (LES), which provides good center beam candle power (CBCP). The Lumileds LUXEON CoB Compact Range LEDs feature a single 6.5mm optical LES that provides high flux densities and high efficacy. Industry-leading thermal resistance allows for smaller heat sinks, and the assembly’s ceramic substrate offers excellent protection in high-potential (HiPot) testing.
