HE Spring-Terminal inserts combine spring conductor connections with rectangular male MSB and female FSB bodies. Available contact counts are 6, 10, 16 and 24 plus protective earth. Each size has a dedicated male and female outline, so the full suffix matters when checking the space behind the insert.
Models and enclosure sizes
| Contacts, plus PE | Male model | Female model | Hood and housing size |
| 6 | SO-HE-006-MSB | SO-HE-006-FSB | H6B |
| 10 | SO-HE-010-MSB | SO-HE-010-FSB | H10B |
| 16 | SO-HE-016-MSB | SO-HE-016-FSB | H16B |
| 24 | SO-HE-024-MSB | SO-HE-024-FSB | H24B |
The model endings MS B and FS B on the drawings correspond to MSB and FSB in the model table. Select the required contact count and complementary gender, then check the hood entry and housing mounting style against the cable assembly.
Wire preparation and contacts
| Property | Specification for the listed MSB/FSB models |
| Termination | Spring terminal |
| Conductor cross-section | 0.14-2.5mm² |
| Wire size | 26-14AWG |
| Stripping length | 7-9mm |
| Contact material | Copper alloy |
