Product Features
JWXC-2000 type infinite relay is used as track repeating relay in AC counting code track circuit.
Product Usage
The JWXC-2000 type infinite relay is used as a track repeating relay in the AC counting code track circuit, and is used in a 12V DC circuit.
Features
1. The relay is a heavy elastic DC electromagnetic relay, which uses the principle of "constant gravity" to force the moving and closing contacts to open when the coil is de-energized.
2. It adopts silver-silver oxide contact, which has the characteristics of strong anti-adhesion and low contact resistance.
3. The magnetic circuit adopts electromagnetic pure iron material with small residual magnetism, and installs the stop piece at the closed position of the armature and the iron core to ensure the minimum air gap of the magnetic circuit, prevent the ferromagnetic parts of the magnetic circuit from magnetization, and ensure the reliable fall of the relay.
4. The contact system is composed of ordinary contacts, and there are two groups of ordinary contacts for switching on and off.
5. The rated voltage of the relay is DC 12V.
Applicable environment
The applicable environment of the relay is:
a) Ambient temperature: -40℃~+60℃;
b) Relative humidity: not more than 90% (temperature +25℃);
c) Air pressure: not less than 70kPa (equivalent to an altitude below 3000m);
d) Vibration: the vibration frequency is not more than 15Hz, and the amplitude is not more than 0.45mm;
e) Working position: horizontal;
f) There should be no harmful gas causing explosion hazard around, and good dust-proof measures should be taken.
Applicable characteristics Mechanical characteristics
Number of contact groups: 2QH;
Identification pin number: 12, 55;
Contact gap: not less than 1.2mm;
Pallet gap: not less than 0.35mm;
Contact pressure: the dynamic contact point is not less than 250mN; the dynamic disconnection point is not less than 150mN;
Contact uniformity error: not more than 0.20mm.
