The LC506-KB Chemical Resistant Telephone is engineered for safe and reliable communication in the harshest industrial environments. Its housing is made from heavy-duty GRP (Glass Reinforced Plastic), which is highly resistant to chemicals including acids, alkalis, and lubricants. Designed to withstand impact, shock, and extreme weather conditions, this rugged telephone ensures dependable operation where standard devices would quickly fail.
With an IP66 weatherproof rating, a vandal-resistant 83 cm armored handset cord, and a fully rugged keypad, the LC506-KB provides reliable communication for mission-critical applications. Available in both Analog and SIP (VoIP) versions, it offers maximum flexibility: the analog model is line-powered and compatible with standard PBX systems, while the SIP version supports PoE or 12V DC power with an RJ45 port for easy network integration.
This Chemical Resistant Telephone is ideal for chemical plants, oil and gas facilities, power stations, heavy industry, railways, transportation hubs, and military sites—any location requiring robust, secure, and durable communication equipment. Certified to CE, FCC, IK10, RoHS, and ISO9001 standards, it guarantees compliance and long-term performance even in the most demanding conditions.
