Capacitive sensors

Sensors

Capacitive sensors are used for the non-contact detection of any objects. In contrast to inductive sensors, which only detect metallic objects, capacitive sensors can also detect non-metallic materials.

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
