This breakout board provides RJ-11 jacks for up to 8 Creltek Limit Sensors. Each jack provides power, ground, and signal lines to the sensor along with proper signal termination. Miniature screw terminal blocks provide connections back to your motion control system for each sensor. “Active Low” outputs are compatible with Shapeoko 1 / 2 / 3, gShield, TinyG, Carbide 3D, and more!
Works natively with 3.3V power supplies, and an optional on-board voltage regulator also allows use with 5-18V power supplies.
The latest version of this breakout board (v2.1) provides true open-collector outputs for interfacing directly with motion controller inputs up to 24V. These outputs are "active-low" and capable of sinking over 200mA each, and switchable 4.7k pull-up resistors are included. Special noise-reduction circuitry is also included on the sensor inputs. Because the outputs are a true-open collector design, they can simply be wired directly together to "combine" the signals multiple sensors. This is perfect for motion controllers that may have a limited number of sensor inputs (e.g. 3: x, y, and z), but you would like to use two limit sensors on each axis (e.g. "maximum" and "minimum" travel sensors).
Fully assembled and ready to use, and can even be panel-mounted if desired, for a truly professional installation!
To help us make sure your breakout board is configured correctly, please specify which motion controller you plan to use it with, before purchase.
Wiring not included. Please see the Creltek Limit Sensor page for sensor wiring purchase options.

I'm an avid electronics hobbyist and a talented programmer with a passion for creative problem-solving, design, and systems integration. As a member of the Creltek design group, I enjoy finding elegant solutions to complex problems, and combining hardware and software in new and unique ways. I maintain an extremely wide range of interests, and strive to stay on the cutting edge through constant innovation and application, both at work and during personal pursuit in my free time.
My current electronics research includes LED lighting, resonant high-frequency switching power supplies, embedded systems, multi-core microcontrollers, digital audio and MIDI, and the design of reusable circuit modules for rapid prototyping, research, and development.
My day job involves managing the IT department and teaching at a small private college. You can check out my LinkedIn profile here: https://www.linkedin.com/in/kevpatt
Creltek is a private technology design group engaged in innovative software and hardware integration, research, and development. We strive for high quality and excellence by design.
