Are you taking a chance with low-cost sensors?

Don’t take chances with low-cost sensors. Some companies have been severely scaling back on sensor quality to meet price targets. Be on the lookout for these telltale signs of poorly engineered or manufactured sensors:

• Varying sensing distance: to drive out costs, some manufacturers are eliminating the final distance calibration step. This means the actual sensing range can vary up to 30% from the specifications.
• Temperature compensation: affecting mostly inductive proximity sensors, this is one of the more technical areas of sensor design. Special circuits and design methods eliminate the large operating distance variation seen with some low-cost sensors.
• Adequate electrical protection: there are numerous methods to protect a sensor’s output circuit, not all are created equal. Many do not take into account overvoltage, overcurrent, short-circuit, reverse supply polarity, mis-wiring, and energy backfeed from the load.
• EMI resistance: influence from electro-magnetic interference (EMI) noise can cause false triggers leading to machine malfunctions. It takes years of experience and testing to make sensors that will operate reliably near motors and drives.

Fortunately, there is an answer to these potential problems: the Global line of sensors offered by a reliable sensor manufacturer with decades of proven experience. These products are not built down to price, but instead are built up to the highest standards in the industry. By utilizing highly automated product lines and funneling usage to fewer part numbers with broader application potential, the Global line is one of the most cost-effective sensors programs available today, and without sacrificing any quality or reliability. Bottom line? You don’t need to sacrifice quality or reliability in order to meet your cost budget. For more information, see the entire Global line here.
