ZKTeco SA40 Access Control Terminal

Overview

What it is

The ZKTeco SA40 is a compact standalone access control unit for a single door. It combines a keypad with a Radio Frequency Identification (RFID) card reader, so users open the door with a card, a 4 to 6 digit PIN, or both together. Users are added and removed directly on the device, with no software or network required.

What it is used for

It suits offices, server rooms, store rooms and apartment entrances where one door needs controlled entry without a networked controller. It is a common choice for replacing a mechanical key with cards issued to staff.

Key features

• Dual frequency reading: 125 kHz EM cards and 13.56 MHz IC cards (MIFARE S50, S70, EV1)
• 2,000 user and 2,000 password capacity
• Three verification modes: card only, password only, card and password
• Onboard lock relay plus inputs for a door sensor, exit button and doorbell
• Operates from 9 to 15 V DC, from -20 °C to 60 °C
• Slim 103.5 x 86 x 19 mm housing

Buying considerations

The SA40 has no network port, so it keeps no central log and cannot be managed from attendance or security software. If you need reports or multi-door management, choose a networked terminal or controller instead. Card type does not need to be decided in advance because both frequencies are read.

Compatibility and what you need

Plan for a 12 V DC power supply, an electric lock (maglock or strike), an exit button and, optionally, a door contact. Cards or key fobs in either 125 kHz EM or 13.56 MHz MIFARE format are required for card entry.
