Product Description
This compact 2.5 mm earphone socket is purpose‑built for communication equipment that needs reliable, sealed audio output in tight enclosures. The right‑angle PCB mount brings the receptacle to the edge of the board for slim housings, while an IP67 sealing system (front o‑ring and internal gasket) protects against dust and water ingress. It supports stereo TRS plugs for dual‑ear earpieces and can be configured for mono TS use or optional TRRS pinouts when headsets with microphone are required. Spring contacts and gold‑over‑nickel plating deliver low contact resistance and clean audio, and optional internal switching enables jack‑detect or auto‑mute/route functions when a plug is inserted. A metal shield with multiple ground tabs improves EMI immunity in RF‑rich radio environments. Available in THT or SMT right‑angle variants for automated, lead‑free assembly.
IP67 sealing:
- Dust‑tight (IP6X) and water‑resistant to IPX7 with compatible sealed plug; typical test 1 m, 30 minutes
- Front bezel o‑ring plus internal rear gasket; optional hinged or tethered dust cap for unmated sealing
- Drain and vent features available to prevent trapped moisture; conformal‑coat friendly
Electrical (typical, verify per datasheet):
- Interface: 2.5 mm jack accepts 3‑pole TRS (stereo) and 2‑pole TS (mono); optional 4‑pole TRRS
- Rating: up to 0.5 A, 30 V AC/DC (signal level)
- Contact resistance: ≤50 mΩ initial
- Insulation resistance: ≥100 MΩ at 100 VDC
- Dielectric withstand: 500 VAC, 1 minute
- Optional detect pin and normally‑closed switching on tip/ring/sleeve
- ESD/EMI: metal shield and ground tabs; optional ESD ring/bezel
Mechanical:
- Mounting: right‑angle PCB, SMT or THT; locating pegs and reinforced hold‑downs
- Mating life: 5,000–10,000 insertion/withdrawal cycles
- Insertion/withdrawal force: tuned for secure retention; 2–10 N typical
- Operating temperature: −25 to +85 °C (−40 to +85 °C optional)
- Housing: high‑temperature UL94V‑0 plastics (PBT/LCP); shield in stainless steel
- Nose length options for thick bezels or glove‑friendly access
Applications:
- Handheld two‑way radios, PTT handsets, dispatch consoles
- Intercom base units, rugged phones, security earpieces
- Portable scanners, POS terminals, field instruments, public safety equipment
- Stereo earpiece outputs for dual‑ear headsets in communication systems
Customization options:
- Pinout: TRS stereo (tip=L, ring=R, sleeve=GND), mono TS, or TRRS headset (CTIA/OMTP)
- Switching: plug‑detect and normally‑closed circuits for auto‑mute/route
- Shielding: full metal shell, ground tab count, ESD bezel
- Sealing: o‑ring size, rear gasket style, unmated dust cap type
- Termination: SMT vs THT, hold‑down geometry, pick‑and‑place cap for reflow
- Contact plating: gold flash, selective gold thickness, hard gold
- Housing color/finish, logo/marking, extended nose or panel adapter
Design notes:
- Reserve plug clearance at the panel and keep analog traces short, away from RF/SMPS nodes
- Stitch ground vias around shield tabs; use star ground to minimize hum and interference
- Debounce jack‑detect in firmware; confirm TRRS standard (CTIA common) if using microphone
- IP67 depends on mating with a sealed plug or using an unmated dust cap; validate to target test profile
