Inductive sensors

Sensors

Inductive sensors are nowadays indispensable for industrial usage. As compared to mechanical switches they offer almost ideal conditions: non-contact operation free from any wear and tear, high switching frequencies and accuracy. In addition, they are insensitive to vibration, dust and moisture. Inductive sensors detect all metals without contact.

Switching amplifier for Namur sensors according to 94/9/EG (ATEX)

NAMUR switching amplifiers evaluate the sensor signal and control the output. They meet all requirements of the ATEX directives. Switching amplifiers with relay and active transistor and potential-free optocoupler outputs are available. The control circuits hold the approval Ex II (1) GD [EEx ia] IIC. The amplifiers are designed for the connection to NAMUR sensors according to DIN EN 60947-5-6 and mechanical switches. They provide the supply voltage for the intrinsically safe circuit.
Type
housing for rail mounting
Output
1x relay 2x relay 2x opto coupler 2x DC PNP
