What connection types are used for field wiring?
Spring‑type removable terminals accept solid and finely stranded conductors with ferrule/crimp end processing within the specified cross‑sections and facilitate replacement without rewiring the device.
How does the unit behave under vibration and shock?
It is specified to withstand vibration up to 0.75mm at 5 to 500 Hz and shock loading of 15 g for 11 ms, supporting operation in typical industrial settings.
How are semiconductor outputs configured and limited?
The device provides a safety‑related contactless semiconductor output with a DC switching capacity up to 1.5A at 24V and defined Pulse and recovery timings for safe switching sequences.
What environmental ranges should be observed for reliable use?
Operational ambient temperature is rated from -20 °C to +60 °C with storage and transport tolerances to -40 °C and +85 °C, and altitude limits up to 2,000 m.
What is the expected service life under normal use?
Mechanical operating cycles are typically around 10,000,000, supporting long‑term deployment in production applications.
