M12 versions of the sensors are available with sensing distances of up to 12mm – a capability which, according to wenglor, is “unmatched on the market to date”.
Some versions of the sensors incorporate an IO-Link interface which can connect them into networks and allow three different signals to be assigned to their outputs – NPN/PNO, NC/NO or error signals. This in, turn, means that fewer variants of the sensors are needed, reducing stockholding for users.
The use of a technology called weproTec (wenglor proximity technology) means that mounting distances between the sensors can be reduced by more than half, and in some cases, eliminated entirely.
Built-in diagnostics ensure that if a sensing coil is damaged, if a sensor’s internal temperature is too high, or if there is a short-circuit, this information is communicated to the controller and indicated by flashing LEDs.
Wenglor says that the extra functions have been integrated into the new sensors without any increases in price.
