Nano SIM + TF Card Combo Connector | Push-Push PST Pair SMD SIM Socket

Highlight

1. Mechanism: Push-Push Eject Structure: Push-to-lock / Push-to-eject, no separate eject pin. NOT Push-Pull / NOT Hinge type. Optimized cam track solves the top failure pain point: uneven end-user pushing force that causes cards to stick, jam, and lead to push-push failure.
2. Ultra-Long Durability: 50,000 Mating Cycles Guaranteed. Phosphor bronze spring contact beam with stress-relief curved design suppresses metal fatigue under frequent hot plugging; far exceeds the industry-standard 10,000-cycle rating for high-cycle IoT, handheld terminals.
3. Anti-Card-Blocking & Anti-Reverse Insertion Design: Molded polarisation rib + mechanical stop structure. Wrong-direction insertion is physically blocked, preventing users from forcing a misaligned SIM/TF card to damage contact springs or the lock cam. Eliminates field RMA from card jams & bent pins.
4. Built-in Card Detect Switch: Hardware card presence signal for host MCU detection.

Technical Specifications Table

Cross Reference / Drop-In Replacement (Compatible Big Brands)

Pin-to-pin & footprint compatible with mainstream international combo SIM+TF sockets: Molex 1042391430, Hirose DM3N series, TE 2199337 series, JAE ST11S series.

Advantage: Direct PCB replacement, no board redesign required. We improve cam & spring structure to fix the original OEM jam / short-lifetime weakness.

Product Features

Engineer Selection Guide

1. Push-Push vs Push-Pull vs Hinge: This model = Push-Push. Choose when no external tray is preferred; best for thin enclosures. If your end-user needs a physical card tray, select Push-Pull type instead. Hinge is mainly for low-cycle consumer use.
2. Cycle rating selection guide

• Consumer low-frequency use: ≥10k cycles
• Industrial / field service / frequent swap: Select this 50k version

3. Layout reminder: Reserve clearance for push-push cam travel on PCB; avoid plastic enclosure pressing directly onto card top.
4. Plating note: Hard gold contact is mandatory for high-cycle / humid environment; tin plating only for static, rarely swapped cards.
