Front panel sealing to IP67 is achieved by a PBT thermoplastic sealing “O” ring fitted into a premachined groove on the body of the switch before it is inserted into the panel hole cut-out. It is held onto the panel by means Contacts: of a brass hex nut tightened down by a 14mm spanner, to a torque of between gold plated palladium nickel 1.5Nm to 3.0Nm to achieve the correct sealing pressure. A “D” flat is provided to Terminals: prevent rotation. gold plated brass Designs and specifications are subject to change 37 800.544.3354 without notice due to product improvement.
