NAR 8258 – Railway Pressure Switch
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 +125°C and the triple overpressure protection make the NAR 8258 the ideal choice for railway vehicles in rough environmental conditions.
Features
- Measuring accuracy 0.3 %
- 1 or 2 PNP transistors
- Parameterization via smartphone App (Android)
- Switching current up to 400 mA
- Dielectrical strength: 710 VDC, meets EN 50155 (Railways)
