Sentex Systems SN2102461D-316L-TNJ Gate Access Keypad
 |
The SN2102461D‑316L‑TNJ is a Sentex Systems gate access keypad that interfaces with the company’s telephone entry and gate operator controllers via a ribbon cable. Common failures on this model include burned or corroded membrane contacts, damaged PCB traces from vibration or moisture ingress, and power supply voltage drops to the control board. First‑check diagnostics: verify 24 V DC input at the keypad connector, inspect the membrane for visible wear or residue, and confirm continuity of the ribbon cable and solder joints on the PCB; if a fault code is displayed, cross‑reference it with Sentex’s service manual for specific error indications.[oss-gpt-20b] |
