The DIN41612 Right Angle Female Type 0.33Q Connector is a specialized, inverse-configuration Eurocard connector designed for high-density backplane and PCB interconnect applications in industrial and telecommunications systems. This connector fully complies with the DIN 41612 / IEC 60603-2 standard, which defines the mechanical and electrical specifications for two-part connectors used in rack-and-panel and backplane architectures. The "0.33Q" designation indicates a specific Type Q sub-variant within the DIN41612 family, characterized by its unique contact arrangement and dimensional profile. The "Inversed" (or "Inverted") configuration is a critical design feature—unlike standard DIN41612 connectors where the male plug is board-mounted and the female receptacle is backplane-mounted, the Inversed series reverses this convention. In the Type 0.33Q Inversed design, the female receptacle is mounted on the PCB, while the corresponding male connector resides on the backplane. This inversion provides design flexibility for specialized system architectures, particularly in telecom applications where maintenance and replacement strategies favor this reversed arrangement. The right angle orientation (90°) positions the connector's mating interface parallel to the PCB surface, enabling low-profile, side-entry cable or backplane connections in space-constrained enclosures.
The Type 0.33Q connector features a 20-position contact arrangement, offering a moderate pin count suitable for compact signal and power distribution applications where full-size 64, 96, or 128-position DIN connectors would be excessive. The 20-position configuration provides sufficient signal lines for control buses, auxiliary interfaces, or power supply connections while minimizing PCB real estate consumption. The female receptacle design incorporates shrouded female contacts that accept corresponding male pins from the mating connector, providing reliable electrical engagement with insertion/extraction forces compliant with DIN41612 specifications. As a right-angle component, the connector's termination style is typically through-hole (DIP) solder type, with contacts exiting parallel to the PCB surface. This orientation is ideal for applications where the mating connector approaches from the side rather than vertically, such as daughter cards plugged into backplanes, mezzanine card architectures, or cable interfaces in rack-mount equipment. The insulator housing is molded from high-performance thermoplastic materials—typically PBT (Polybutylene Terephthalate) with 30% glass fiber reinforcement—rated UL94 V-0 for flame retardancy, ensuring mechanical stability, dimensional accuracy, and heat resistance during wave soldering or reflow processes. The housing color for DIN41612 Type Q connectors is often gray or beige, following traditional Eurocard aesthetics, though variations exist by manufacturer.
The DIN41612 Right Angle Female Type 0.33Q connector delivers robust electrical performance suitable for industrial and telecom-grade applications. Electrical characteristics typically include a current rating of 2.0 Amps per contact, a voltage rating of 250V to 380V AC/DC (depending on manufacturer specifications), a contact resistance of 20mΩ maximum, an insulation resistance of 1000MΩ minimum, and a dielectric withstand voltage of 1000V AC for one minute. The operating temperature range spans from -55°C to +105°C, ensuring reliable performance in harsh industrial environments, outdoor telecom cabinets, and automotive test systems. The female contacts are fabricated from phosphor bronze or brass with selective gold plating over a nickel underplating on the mating area to provide low contact resistance, corrosion resistance, and durability through multiple mating cycles (typically rated for 400 to 500 mating cycles). The solder tail termination areas are usually tin-plated for optimal solderability. The insulator material (PBT+30% GF) provides excellent mechanical strength, dimensional stability under temperature variation, and resistance to soldering heat. The Type Q Inversed series is specifically engineered for telecommunications applications, where the inverted contact arrangement (female on PCB, male on backplane) offers advantages in system maintainability and cost optimization compared to standard DIN configurations.
The DIN41616 Right Angle Female Type 0.33Q Connector is deployed in applications requiring Eurocard-compliant interconnect solutions with a moderate pin count and inverted gender configuration. Primary application areas include telecommunications systems (backplane interfaces for switching equipment, base station controllers, and transmission racks), industrial control systems (PLC backplanes, I/O modules, and industrial computers), medical instrumentation (imaging systems and patient monitors), test and measurement equipment, and military/aerospace electronics where DIN41612 standardization ensures long-term availability and interchangeability. Major manufacturers of DIN41612 connectors, including ERNI, Harting, Amphenol, TE Connectivity, and Antenk, offer Type Q variants with right-angle, press-fit, or IDC termination options. In summary, the DIN41612 Right Angle Female Type 0.33Q Inversed 20-Position connector is a specialized, high-reliability interconnect solution that combines DIN41612 standardization with an inverted gender configuration, 20-position density, and right-angle orientation—making it an ideal choice for telecom and industrial applications requiring compact, serviceable Eurocard connections.
