About
The pressure switch NAR 8258 with 1 or 2 switching outputs and increased accuracy of 0.3 % was specifically designed for railway vehicles (EN 50155) and has a long-term stable thin-film-on-steel sensor cell. The wide temperature range from -40°C to +85°C and the triple overpressure protection make the NAR 8258 the ideal choice for railway vehicles in rough environmental conditions.
