The EP-Series is a cost-effective sensor line developed by BRSEN in recent years for high-volume usage, offering a lower price point than the R-Series without compromising on functionality. The E-Series is primarily divided into the mechanical external EP, ER models, and the hydraulic integrated professional OEM product EH models. The core technology remains magnetostrictive technology, which boasts basic advantages such as contactless operation, shock resistance, interference immunity, and reliability, all of which are present in the E-Series. Therefore, it performs similarly to other series, but lacks the range of output functions and stroke options. It is widely used in general industrial automation applications.
The EP type position sensor offers high repeatability precision with outputs in both analog voltage and current. Zero points and ranges are factory-set, allowing for on-site installation without re-calibration and no routine maintenance required after use. Like other BRSEN position sensor products, the EP model has passed EMC, IEC interference, vibration, and impact tests and is also CE certified. The housing complies with IP65 standards, with the option for a slider or suspended magnet installation to suit application conditions. The EP model, with its moderate price, reliable performance, and non-wearing characteristics, is one choice for replacing resistive potentiometers or LVDTs. Particularly in applications like injection molding machines, blow molding machines, and stamping machines, its cost-effectiveness is more pronounced. Experiments have shown that the non-contact EP position sensor has a significantly longer lifespan compared to contact potentiometers under harsh working conditions.

EP Type Shell Dimensions and Installation Instructions
Description: (1) The number of fixing clips required for installation corresponds to the range. It is recommended to add one clip for every 500mm increase in range.
(2) The EP series products use floating magnets for position measurement: directly mounted on moving parts, not in contact with the sensor. Allows ±3mm lateral offset and up to 10mm vertical gap.
