product name There are extremely strengthened contact relays: JYJXC-160/260 Product Usage The JYJXC-160/260 type has pole reinforced contact relay is used as a two-start relay in the signal switch control circuit. Mechanical properties Number of contact groups: 2DF, 2DFJ; Identification pin number: 15, 54; Contact gap: ordinary contact is not less than 4.5mm; reinforced contact is not less than 7mm; Pallet gap: ordinary contact point is not less than 0.35mm; Ordinary contact pressure: the positioning contact is not less than 150mN; the reverse contact is not less than 150mN; Strengthen the contact pressure: the positioning contact is not less than 400mN; the reverse contact is not less than 400mN; Contact uniformity error: no more than 0.2mm between ordinary contacts and ordinary contacts and between ordinary contacts and reinforced contacts, and no greater than between reinforced contacts and reinforced contacts 0.1mm. Positioning or reverse position holding force is not less than 4N; Electrical characteristics (at 20c) Coil resistance: 135/220Q Use the coil alone, use 1, 23, 4; Rated value: 24V; Magnetizing value: 64V/64V; Rotation extreme value: forward 10V~16V, reverse 10V~16V; Contact resistance: common contact is not more than 0.05; strengthened contact is not more than 0.1Q. Product function The signal relay is an important component in the interlocking equipment, and is the main equipment to ensure the safe operation of the system. The signal relay can control the switching of the turnout, lock and unlock the route, and control the opening and closing of the signal machine. Its reliability, availability, maintainability and the entire sauna line are the keys to the safety of railway transportation and operational services. Insulation withstand voltage Under the standard atmospheric conditions of the test, the insulation resistance of the relay should not be less than 100MQ. Under the condition that the air pressure is not less than 86kPa (equivalent to the altitude below 1000m), the insulation withstand voltage of the relay should be able to withstand AC sine wave 50Hz, 2000V rms voltage, there should be no breakdown flashover after 1 min, and the voltage during repeated test should be 75% of the original test voltage. Product electrical life The ordinary contact of the relay is connected to DC24V1A resistive load; the strengthened contact is connected to DC220V7.5A, 0.05H inductive load, and its electrical life is 1105 times.
