NAT 8252 – Industrial Pressure Switch
The industrial pressure switch NAT 8252 is available with 1 or 2 switching outputs and features an exceptionally long-term stable thin-film-on-steel sensor cell with triple (optionally 5-fold) overpressure safety. The robust design and the wide temperature range from -40°C to +125°C qualify the NAT 8252 as the ideal solution for a wide range of demanding pressure switch applications
