FEATURES

Choice of three termination styles - solder bucket, straight p.c. and 90° p.c.
Threaded inserts on 90° p.c. versions as standard - accepts a wide range of mounting hardware.
Tinned and dimpled shell options - for EMI/RFI shielding.
Optional boardlock feature for 90° p.c. types - reduces installation time..
