Beyond the standard sensor types used in machine automation—such as photo eyes, limit switches and DC proximity sensors—are a wide range of color, contrast, AC proximity and area sensors. All of these sensors, as well as optical rotary encoders, are used to enable sorting, detection, error checking and positioning for machine automation.
Overview Magnetic proximity sensors are used for non-contact position detection beyond the normal limits of inductive sensors. In conjunction with a separate “damping” magnet, magnetic sensors offer very long sensing ranges from a small package size and can detect magnets through walls of non-ferrous metal, stainless steel, aluminum, plastic or wood. Depending on the orientation of the magnetic field the sensor can be damped from ... Read More
When it comes to detecting position and presence in automated equipment, be sure to consider limit switch as choices available today are robust, and can provide high precision. While photo eyes and inductive switches are popular choices in many applications, precision limit switches can be a better option with repeatable accuracy less than a micron.
PMMI Media Group’s Automation World magazine announced the First Team category leaders in the 2017 Leadership in Automation Program on January 11, 2018. Automation World, a leading business magazine serving automation professionals, launched this community-based program in January 2017.
New V3 series AC powered proximity sensors from AutomationDirect are available in 8, 12, 18 and 30mm sizes. Extended sensing distances for these new sensors range from 2mm shielded and 4mm unshielded for 8mm sensors to 12mm shielded and 18mm unshielded for 30mm sensors.
New design improvements have been made to AutomationDirect’s ProSense® line of temperature switches. TSDA25 series temperature switches are a direct replacement for the TSD25 series and provide higher accuracy and a standard sized 6mm diameter probe.
AutomationDirect’s ProSense® line of instrumentation products now includes the ETS series digital temperature sensors. The ETS series combines a precision RTD sensing element, measuring electronics, and process fitting all in a single stainless steel temperature transmitter probe.
Sensors and transmitters convert a variety of physical properties into discrete and analog signals for use by automation controllers. AutomationDirect offers an assortment of these devices for use in the design and operation of machines and processes to create reliable, robust and consistent automation. It may only take a small change in a physical property ... Read More
