Procurement Notes

Verify the specific part number suffix 'S' to ensure the inclusion of the safety key feature, as standard versions may lack this security mechanism. Confirm compliance with RoHS and REACH standards if required by project specifications. Cross-reference the impedance values at 25 MHz and 100 MHz against the datasheet to validate performance requirements for the target frequency range.

Selection Notes

Select this component when cable security against accidental or intentional removal is critical. The 14.5 mm aperture accommodates cables of corresponding outer diameters. Ensure the application environment falls within the operational temperature limits defined by the manufacturer. Consider the physical footprint of 40x30x20 mm for spatial constraints in the assembly.
