LXD-20 Limit Switch
Application
LXD series fire limiter (hereinafter referred to as limiter) is mainly used in power lines with AC 50Hz, voltage up to 380V, and DC voltage up to 220V, for 0.5 tons to 10 tons of CD1 type, MD1 type wire rope electric hoist. It is used for lifting and lowering limit protection, which can directly break the main circuit of the lifting motor.
Advantage
- Using high-quality cold-rolled steel metal shell, it can effectively resist the impact of the outside world, and it is strong and wear-resistant and not easy to fade.
- There are five powerful protection functions such as splash-proof, dust-proof, shock-proof, anti-magnetic, and anti-static.
- There is a rubber sealing ring on the edge of the base, the push-pull rod moves smoothly, does not get stuck, durable, and has a mechanical life of more than 15,000 times.
- Insulated dustproof wiring port, high protection level, convenient and practical, stable structure, not easy to damage, easy to install, strong durability.
- The internal use of national standard parts, the electrical conductivity is stronger and more stable.
