A speed sensor is an interconnect device that detects the rotational or linear velocity of a moving component and converts that motion into an electrical signal with a frequency or pulse rate that is proportional to speed. The two dominant speed sensor types are variable reluctance (VR) sensors, which generate a self-powered analog signal asRead More

The connector industry continues to contract, even as the demand for interconnect products increases. See what acquisitions helped change the connector industry in 2025. Demand for interconnects continues to grow, fueling a continuing wave of mergers and acquisitions that leaves fewer (and now, larger) companies left in the market. In 2025, more suppliers expanded services,Read More

Meet the Sensor: Current Sensors Current sensors detect electric current and generate a signal proportional to that current. The signal, which may be analog or digital depending on the sensor and the application, can be used to display the measured current, stored in a data acquisition system for later analysis, or used for control purposes.Read More

What are CO2 Sensors? CO2 (carbon dioxide) sensors measure CO2 to monitor indoor air quality, often as part of an HVAC system. They are also found in medical equipment and various industrial applications. The amount of carbon dioxide in the air is an indicator of the performance quality of the HVAC system. CO2 sensors helpRead More

Meet the Sensor: Quantum Sensors Quantum sensors are a highly complex sensing device that measures physical quantities with extreme precision. They can measure time, temperature, distance, gravity, electromagnetic fields, and more. They use the principles of quantum mechanics, such as superposition, entanglement, and quantum coherence, to measure physical quantities. They range in size and abilities,Read More

Creating a realistic touch sensation is key to improving user experience by instilling confidence that the performed operation has been reliably completed. Haptic technology creates a touch experience in electronic devices with the use of force feedback, vibration, or motion. It is commonly used in game controllers and has seen increased demand in automotive andRead More
