ZOFLEX® ZL45.1 is a pressure sensitive conductive rubber with a Shore A hardness of 45. Its resistance change with pressure is very drastic: the material is at a high resistance state>30MΩ when applied pressure is below the actuation pressure; the material is at a very low resistance state (can be ≤0.1Ω) when applied pressure is equal or above the actuation pressure. It can be used in applications such as conductive rubber keypads, mechanical pressure switches, RF gaskets and etc… Its unique pressure activated conductivity simplifies product design since it can rest on the conductive media without creating electrical shorts. Compared to typical carbon pills (0.15” diameter, 0.015” thick), it has a similar actuation force (<200g) but has a lower contact resistance (200Ω typical for carbon pills), and does not create potential shorts due to carbon residue accumulation on PCB traces.
