MR - special relay the special relay MR features MR relays are fail-save and universal useable elements with excellent contact load and high pull-in sensitivity. • different versions enable the ideal adaption for different applications. • short contact springs enable bounce-free switching. • special synthetic–layers and a substantial over-travel are the reasons for the constancy and safety at a large number of operations, also in bad climate conditions. The big bobbin and the variability of the contacts make a lot of versions for different applications possible. applications • industrial electronics • automation and control 48 catalog 2002 e / 04.03 Special relays with different contact versions for several applications. order numbers contact specifications (see data sheet for curves) soldering version MRL ...
