Thermoelectric voltage terminal block pair, USA type N, Connection method: Screw connection, Number of positions: 1, Cross section: 0.2 mm² - 4 mm², AWG: 24 - 12, Width: 10.4 mm, Color: gray, Mounting type: NS 35/7,5, NS 35/15, NS 32 

## Why buy this product 

These special terminal blocks are used to extend thermocouple equalizing conductors in corresponding measuring circuits 

> wy This ensures that no false thermoelectric voltages result at the junctions of the thermocouple/terminal block/equalizing conductor and that the basic values according to EN 60584/DIN EN 60584 are observed 

> Ww The equalizing conductors are made from materials which, up to temperatures of 200°C, have the same thermal characteristics as the corresponding thermocouples
