Conductive Silicone PCB Shielding Gasket 1570

PCB shielding gaskets are a Surface Mountable Technology (SMT) compatible electric elastomer connector which has good elastic recovery and electric property

The 1570 series PCB shielding gaskets are a Surface Mountable Technology (SMT) compatible electric elastomer connector. Our 1570 series has good elastic recovery and electric property, so it offers not only cushion, but also electrical connecting and grounding between electrical objects and PCB. The 1570 is a rectangle with narrow width and is mounted on PCB board. So this can replace Shield Can or EMI Dispensing Gasket or other electric contacts. Recommendation of compression is 10~30% of its height.
