Residual current lr

The residual current flows in the load current circuit when the output is blocked. The residual current must be considered when switching sensor in parallel.

Minimum load current lm

The minimum load current is necessary for flawless operation with two wire devices.

Current consumption

The current consumption is the maximum value of the no load current to that the sensor can absorb without a load

Ambient temperature

The ambient temperature indicates the maximum allowable range for the sensor

Electromagnetic compatibility EMC

The EMC class is a measure of the noise immunity of the sensor against external electrical and magnetic influences. The information is base on the standard EN 61000-6-2

Switch-on impulse suppression

Optimum sensors have a switch-on suppression that blocks the output during the switch-on phase, when the operational voltage is applied.

Protective system

The protective system indicates the protection of the sensor against penetration of foreign bodies and water to EN 60529

LED display

Optimum sensors with yellow light-emitting diodes indicate the switching status optically

Housing material

The housing material determines the chemical resistance of the sensor against

external influences. For special applications, other housing materials are available.

Connection

The connection of the sensor is accomplished through plug-in

connections or cables. Different cable types and lengths are available upon request.

Instructions for mounting

Mounting

For flush mounting the sensor can be built into material up to its active surface without changing its characteristics. For non-flush mounting a metal-free zone around the sensor must be allowed for. A free zone to the material opposite the sensor must be maintained for all sensors
