SIST EN 175301-801:2007 is the Slovenian adoption of EN 175301-801:2006 from CENELEC. It specifies high-density rectangular connectors with round removable crimp contacts, including 15, 25, and 40 to 64 contacts plus protective earth contacts (PE), for manufacturers, test houses, and users who need a defined mating interface and quality-assessment basis.
What does SIST EN 175301-801:2007 specify?
SIST EN 175301-801:2007 is a detail specification for high-density rectangular connectors with round removable crimp contacts and crimp termination. Clause 1 sets the scope, performance level 1, and assessment levels B and G.
The standard is organized into clauses for references, type designation, common features, dimensions, gauges, characteristics, test schedule, quality assessment procedures, and ordering information. In practice, that means the document covers both the connector design and how it is checked for qualification and production release.
What are the key requirements of SIST EN 175301-801:2007?
Identification, styles, and mating
Clause 3 defines the type designation system, so orders and data sheets can identify the connector style, number of contacts, contact gender, contact finish, latching option, and assessment level in one code. That matters because the wrong code can mean a non-mating part or the wrong quality route.
Clause 4 lists the main styles: fixed connector Style A and Style B, free connector Style C, and connector insert Style E, with male and female variants. The standard also defines how the parts must mate, including permitted alignment tolerance and inclination, so mounted parts can still engage without damaging contacts.
Dimensions, contacts, and marking
Clause 5 gives the principal dimensions for male-contact and female-contact versions, mounting dimensions, locking mechanism dimensions, and housing dimensions. It also limits removable crimp contacts to wire gauges from 0.14 mm² to 2.5 mm², which is the practical wiring range a designer must keep within.
Clause 5.4 requires marking with the manufacturer identification, the EN type designation, and contact-position marking on both faces of the insert. If insulating parts are marked, the plastics identification follows EN ISO 11469 and EN ISO 1043, which helps with material traceability and recycling handling.
Locking, gauges, and operating performance
Clause 5.6 defines the locking mechanism interface between Styles A, B, and C, and Clause 6 provides sizing gauges, retention-force gauges, and locking-mechanism gauges. These gauges matter in production because they verify correct geometry, retention, and latch function without relying only on visual checks.
Clause 7 sets the climatic category, electrical clearances and creepage distances, voltage proof, current-carrying capacity by derating curves, and a protection level of IP54B or higher in the mated and locked condition. For users, this is the part that links the connector to the electrical stress, environment, and enclosure protection it can tolerate.
Testing and quality assessment
Clause 8 defines the test schedule, with preliminary tests and separate AP, BP, CP, and DP groups. The tests cover visual and dimensional checks, polarization, contact resistance, insulation resistance, voltage proof, insertion and withdrawal forces, damp heat, dry heat, cold, static load, fluid resistance, cable-clamp performance, impact, and crimped connections.
Clause 9 sets qualification approval and lot-by-lot quality control. In practice, this means the standard is not only a geometry document - it also provides the test route for approving a design and controlling ongoing production.
What terms does SIST EN 175301-801:2007 define?
- PE - Protective earth contact, used where the connector includes an earth connection in addition to the signal or power contacts.
- Fixed connector - The mounted half of the connector pair, with Styles A and B used for bulkhead or box mounting.
- Free connector - The cable-connected half of the pair, with Style C as the straight plug and Style E as the connector insert.
- Variant M - The male-contact version of a style.
- Variant F - The female-contact version of a style.
- Latching mechanism - The locking interface that holds the mated connectors together and is checked with dedicated gauges.
- Sizing gauge - A gauge used to verify connector dimensions and contact retention.
Who uses SIST EN 175301-801:2007?
SIST EN 175301-801:2007 is used by connector manufacturers, cable assembly makers, test laboratories, and quality teams that approve or inspect assessed-quality connector products. It is also relevant to buyers and design engineers who need a specified mating interface, locking system, and test regime for rectangular connectors with crimp contacts.
What changed in SIST EN 175301-801:2007 from the previous edition?
SIST EN 175301-801:2007 supersedes EN 175301-801:1999.

- EN 60068-1 - Gives the climatic-category test framework used for environmental classification.
- EN 60352-2 - Gives general requirements and test methods for solderless crimped connections.
- EN 60512 series - Supplies the connector test methods used throughout Clauses 7 and 8.
- EN 60529 - Defines IP code tests used for the protection requirement and IPXXB checks.
- EN 60664-1 - Provides insulation-coordination principles for clearance, creepage, and impulse withstand data.

- EN 61076-7-100 - Gives the cable-sealing detail specification referenced for some cable-clamp tests.
- EN 61984 - Provides safety requirements and tests for connector systems.
- EN ISO 1043-1, EN ISO 1043-2, EN ISO 11469 - Provide plastics identification and marking rules.
- EN ISO 1302 - Gives the surface-texture notation used for gauge finish.
- EN ISO 6743-4 - Identifies the hydraulic oil used in the fluid test.
- IEC 60410 - Provides the sampling-plan basis for inspection levels and AQL values.
What does the SIST EN 175301-801:2007 document contain?
The standard contains drawings, tables, and test schedules that define the connector interface and how it is verified. It includes figures for connector styles, inserts, locking mechanisms, gauges, mounting arrangements, and static-load test setup.
It also contains dimensional tables for the connector bodies, locking parts, and mounting envelopes, together with gauge dimensions for checking fit and latch performance. The later clauses provide test sequences for qualification, periodic inspection, and delayed delivery re-inspection, which are used in design validation, production control, and certification work.

For fixed mounted connector pairs, the mounting must be kept accordingly in a sufficient small range.
