HC-SR04 Ultrasonic Range Finder Mounting Bracket

Description

The HC-SR04 Ultrasonic Range Finder Module Mounting Bracket is an acrylic bracket designed to mount the HC-SR04, HC-SR04+ or HC-SR05 Ultrasonic Range Finder modules.

PACKAGE INCLUDES:

• HC-SR04 Ultrasonic Range Finder Module Mounting Bracket
• 2x – M3 x 8mm screws/nuts for mounting

The bracket has two holes for mounting it to a surface such as to a robotic vehicle chassis.  The mounting hardware consisting of M3x8 screws and nuts is now included.

The ultrasonic range finder can be inserted from either side of the bracket and with the header facing up or down depending on other mounting considerations.

OUR EVALUATION RESULTS:

The bracket is designed to have a slight press fit where the ultrasonic sensors pass through the holes in the bracket to help hold the module in place.  Since there are variances in the build of the different modules, the fit is sometimes too tight in the area between the two sensors.  If this happens, the bracket can easily be modified by using a box knife, X-Acto knife or similar to scrape away some of the acrylic from the sides of the holes where the fit is too tight.  This is most often an issue with the HC-SR05.  It is easiest to do this while the part still has the protective paper in place to minimize marring of the acrylic.

The US-100 Ultrasonic module has closer spacing of the sensors and would require removal of about 1/8″ of material to make it work with this bracket, so it is not really recommended for that application.

Notes: 

1. The acrylic bracket may vary slightly from the pictures.  Some have a slot cut out for the crystal and some do not.  The slot usually does not line up with the crystal well enough to insert, so it serves no real purpose.
