KNTECH KNEx1 Intrinsically Safe Analogue Explosion-proof Telephone with LCD, IECEx
KNTECH KNEx1 is an analogue telephone for hazardous dust and gas areas. The housing is moulded from SMC 2600 glass-fibre reinforced polyester and the phone is IECEx certified as Ex e ib mb IIC T6 Gb for use in Zone 1 and Zone 2.
The KNEx1 takes its power from the telephone line, so it needs no external supply or battery. It connects to most PABX, PBX and PAX systems. A two-line LCD, stainless steel keypad and 50-entry phone book make it easy to call the control room, while soft-lock functions restrict outgoing calls where needed.
