www .imopc.com Footswitches PX/PA continued PX/PA/03/03 Specification Cable glands Contact blocks Contact ratings Plug and socket footswitches Cable glands are available to enable standard multi-core cables to be connected without the use of conduit. Two sizes are possible: Part number Cable size PG13.5 ø9-12mm PG13.5/6 ø6-9mm Rated thermal current Ith 10A Rated working voltage 500VAC/600VDC Initial contact resistance <25 mOhms Contact gap >2.5mm (2 x 1.25mm conforming to VDE 0660 part 206) Contact material silver Dielectric strength 2000VAC, 50/60Hz for 1 minute between open contacts 2000VAC, 50/60Hz for 1 minute between current-carrying parts and ground Ambient operating temperature –25 to +80 deg. C Ambient humidity 95% r.h. Maximum wire size 2 x 1.5mm 2 flexible, 2 x 2.5mm2 solid Conduit entry PG13.5 All PX series footswitches can be converted to a plug-in style by the addition of an adaptor. See previous page for diagram. The adaptor is screwed into the footswitch and the four flying leads connected to the four terminals of the contact block. Suitable 4-wire plug leads are available. Ratings: 250VAC/300VDC 3A IP67 The contact blocks can also be purchased separately without the footswitches and be used as stand-alone limit switches. The contacts are electrically separated so it is possible to connect different voltages to NO and NC circuits i.e. Zb contacts. The NC contacts also have positive break, i.e. suitable for safety circuits. Contact arrangements: Note: There is space under the terminal cover to allow the fitting of a small amount of control components, e.g. relays, terminal blocks etc., which should be secured to prevent interference with the footswitch mechanism. Terminal screws: M3.5 with rising cable clamps. Maximum screw tightening torque: 0.8Nm (8kg cm). 1NO+1NC VF B501 VF B901 11 2NC 1NO+1NC 2NO VF B601 VF B1001 BS/EN 60947-5-1 AC15 230VAC 6A 400VAC 4A 500VAC 1A DC13 24VDC 6A 125VDC 1.1A 250VDC 0.4A
