New product: Aluminum mounting bracket for NEMA 14 stepper motors

Posted by Ben about 3 hours ago
Tags: new products

This new stepper motor bracket is designed to work with typical NEMA 14-size stepper motors, including all of the NEMA 14 stepper motors we carry. It is made from 2mm-thick black anodized aluminum, and like the larger NEMA 17 bracket we released earlier this year, it features slot cutouts to allow for a variety of mounting options.

For more information, see the product page.

New product: 56:1 Metal Gearmotor 20Dx42L mm

We have added a new gear ratio to our 20D mm line of metal gearmotors. This gearmotor has a 56:1 gearbox, resulting in a no-load speed of 250 RPM and a stall torque of 45 oz-in at 6 V.

New product: Sharp GP2Y0A51SK0F Analog Distance Sensor 2-15cm

Sharp GP2Y0A51SK0F Analog Distance Sensor 2-15cm with wires soldered directly to the sensor PCB.

We are now carrying the short-range Sharp GP2Y0A51SK0F Analog Distance Sensor. Like the GP2Y0D815Z0F we released a few months ago, this sensor has a maximum intended sensing range of 15 cm, but unlike that other sensor, this module tells you where the detected object is in its 2 cm to 15 cm range. Its close minimum sensing distance of 2 cm and high 60 Hz update rate make this a great choice for close-proximity range-finding, or the analog voltage output can be passed through a comparator to make an adjustable-threshold alternative to our digital Sharp distance sensors.

This sensor uses a 1.5 mm pitch JST ZH connector, which is different from the connectors on all the other Sharp sensors we carry. Unfortunately, this means it will not work with the JST PH cables we recommend for use with some of those other sensors. We are working on getting compatible cables, but in the interim, it is not too difficult (but not exactly easy) to solder wires directly to the output pins like in the picture on the right.

This sensor is also quite a bit smaller than most of the other analog Sharp sensors, so it will not work with our new brackets.

A variety of Sharp distance sensors. From left to right: GP2Y0A02, GP2Y0A21 or GP2Y0A41, GP2Y0A51, and GP2Y0D8xx.

New products: MP micro metal gearmotors with extended motor shafts

Several gear ratios of our medium-power (MP) micro metal gearmotors are now available with extended motor shafts:

The extended motor shaft rotates at the same speed as the input to the gearbox and offers a way to add an encoder, such as our new magnetic encoder for micro metal gearmotors (pictured below), to provide motor speed or position feedback.

New products: Pololu Carriers for Sharp GP2Y0A60SZLF Analog Distance Sensor

Last month, we introduced our new carriers with Sharp GP2Y0A60SZLF analog distance sensors, a part we are very excited about and have been trying to get for the past five years. Those complete sensor modules ship with the GP2Y0A60SZLF installed on our compact carrier board, which includes all of the required external components and provides a more convenient interface to the sensor (and a mounting hole!). Well, we are now offering the carrier boards without the sensor for those who already have Sharp GP2Y0A60SZLF units and are looking for an easy way to incorporate them into their projects. The carrier boards are available in two configurations: a 5V version for operation from 2.7 V to 5.5 V and a 3V version for operation from 2.7 V to 3.6 V:
