The Festo MC-LD-12-24DC (Part No. 19145) is an illuminating seal with integrated yellow LED for visual switching position indication on pneumatic solenoid valves. It mounts between the solenoid coil (MSN1 series) and the electrical connector plug (Type A per DIN EN 175301-803), providing an instant visual confirmation that the coil is energized. With only 0.05W power consumption, IP65 protection, and an operating temperature range of -25°C to +85°C, it is suitable for harsh industrial environments. The transparent TPE-U housing and M3 central screw mounting ensure simple installation without additional tools. Applications include machinery status indication, automated production line monitoring, and maintenance diagnostics for pneumatic valve banks.
**Q: How is the MC-LD-12-24DC installed?**
A: It mounts between the solenoid coil and the electrical connector plug, secured by the existing M3 central screw. No additional wiring or tools required.
**Q: Will the LED illuminate when the coil is de-energized?**
A: No, the LED illuminates only when the coil receives power, providing real-time visual indication of the valve's switching state.
**Q: Is this compatible with AC-powered solenoid coils?**
A: No, this is the DC version (12-24V DC). For 230V AC coils, use the MC-LD-230AC variant.
