HZM2C-LG/S General Purpose Electromagnetic Relay - Transparent Housing with LED Status Indicator
The HZM2C-LG/S is a 2-pole changeover (2CO / DPDT) general-purpose relay designed for industrial control panels, automation systems, and electrical distribution equipment. Featuring a fully transparent polycarbonate housing and an integrated red LED coil indicator, this relay allows technicians to verify energization status and inspect internal contact condition at a glance - without disassembly or circuit interruption.
With coil options spanning AC 6V to 380V and DC 6V to 220V, the HZM2C-LG/S series covers virtually every standard control voltage used in global industrial and commercial applications.

What the Transparent Cover Actually Gives You
Most relays hide their contacts behind an opaque shell. The HZM2C-LG/S doesn't.
| Feature | What It Means on the Job Site |
|---|---|
| Transparent PC Housing | Visual contact inspection - spot burn marks, carbon buildup, or contact welding without removing the relay from the socket |
| Red LED Indicator | Instant coil status confirmation. No multimeter needed to verify if the control signal is reaching the relay |
| Visible Coil Winding | Confirm coil voltage marking (e.g., 240VAC) without checking the part number - reduces installation errors |
| Red Actuator Flag | Mechanical indicator shows physical armature position, confirming actual contact closure independent of the LED |
For panel builders and maintenance teams, this translates to faster troubleshooting and reduced downtime. A technician walking a fault can spot a de-energized coil or welded contact in seconds, not minutes.
