SICK IN4000 Series Inductive Non-Contact Safety Switch, 24V dc, Plastic Housing, 3NO, M12

The IN4000 inductive safety switch is used for position monitoring and has an inductive sensor that is activated by metal (e.g. steel ST37), therefore it does not require a separate coded actuator. Due to the non-contact form of operation, this safety switch is straight forward to adjust and install and offers increased resistance to shock and vibration. The response range of the sensor is monitored spatially and over time, providing increased protection against tampering.

One pulsed output (IN4000 Standard) or two OSSD outputs (IN4000 Direct) for direct connection of sensors to a single safety controller

Safe series connection of sensors possible (IN4000 Standard)
Flexi Loop-compatible M12 plug connector

Fast diagnostics via LED status indicator
Cascade up to 9 sensors to one controller for reduced costs (IN4000 Standard)
Flexi Loop now enables a safe series connection with enhanced diagnostic capabilities and minimal wiring effort (IN4000 Direct)
Long service life due to durable and low-maintenance design
Just one safety switch in conjunction with a suitable safety module makes it possible to solve applications up to PL e and Cat. 4 (EN ISO 13849)
The devices are easy to clean, making them suitable for contaminated areas or environments with strict hygiene standards
