Safety technology

Simply reliable:
fail-safe sensors for
mobile machines

Fail-safe inductive sensors

Safety sensor enters the safe

state, logic “0”, as soon as the
sensor is damped
Installation costs and time
reduced as the target is only
required in the end position
Comprehensive self-diagnostics
for maintenance-free continuous
operation
Designed for use in harsh
environments

Target activates safe state

The fail-safe sensors switch into the safe state as soon as the target is
detected inside the safe switch-off distance. The safety-related function
is inverted when compared to the previous fail-safe sensors. This function is
ideal in applications such as the protection of crane installations or industrial
robots because the targets only need to be mounted at the end positions.
Both the number of metallic targets and the installation complexity are
considerably reduced.
Perfectly equipped for mobile use
Thanks to the robust design the sensor is perfectly suited for use in mobile
machines. Applications on mobile machines such as monitoring whether
supports are fully extended or waste bins gripped in the right way.
Neither strong vibration nor extreme temperatures and cleaning processes
affect the function of the fail-safe sensor in any way.
