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.
