Hirose HR10A-10R-10PB(71) — 10-Position Male-Pin Receptacle for Panel-Mount Interconnects
The Hirose HR10A-10R-10PB(71) is a 10-position receptacle with male pins from the HR10A series, designed for push-pull latching and keyed orientation in panel-mount applications. It carries a current rating of 2 A per contact and a voltage rating of 100 VAC / 140 VDC, making it suited for signal and low-power circuits inside equipment enclosures, test instruments, and industrial control panels. Operating temperature spans -25°C to 85°C.
The dual voltage rating (100 VAC, 140 VDC) means the connector handles AC and DC at different peak limits; the DC ceiling is higher because the breakdown mechanism differs.
Push-Pull Latching and Keyed Orientation — Blind-Mate and Mis-Mate Protection
The push-pull fastening mechanism engages with a positive click and releases by pulling the collar — no threads to turn, which speeds up mating in tight panel spaces. The keyed orientation ensures the plug and receptacle align in only one rotational position, preventing pin damage from cross-mating in multi-connector panels. The shell is metal (zinc alloy with nickel finish), providing basic EMI shielding though the connector is listed as unshielded.
Panel Mount with Bulkhead Nut — Secure Rear-Side Fastening
The through-hole solder tails connect to a PCB or can be wired point-to-point. The bulkhead nut provides vibration-resistant retention — the connector stays fixed even when the mating plug is cycled repeatedly. Panel thickness and cutout dimensions follow the HR10A series standard drawing.
Silver-Plated Contacts — High Conductivity, Moderate Cycle Life
For corrosive or high-humidity settings, consider gold-plated variants in the HR10A series. The solder termination is straightforward for hand or wave soldering.
10 Positions vs 12 Positions — Selecting the Right Circuit Count
The HR10A-10R-10PB(71) carries 10 positions. The sibling HR10A-10R-12PB(71) offers 12 positions in the same shell size (shell size 10) with the same 2 A rating, voltage, and silver plating. If your BOM requires 12 circuits, the 12-position version fits the same panel cutout and mates with the same push-pull plug family. For 10-circuit harnesses, the 10-position variant avoids unused cavities.
Mating Half — HR10A-10R-10SB(71) Female Socket Receptacle
The mating connector for this male-pin receptacle is the HR10A-10R-10SB(71), a 10-position female socket receptacle with the same shell size, push-pull latching, and silver-plated contacts. For a cable-mount plug, use the corresponding HR10A plug with female sockets (e.g., HR10A-10P-10S). The keying and shell dimensions are identical across the series, so any HR10A plug of the same position count and gender configuration mates reliably.
It is ROHS3 compliant.
