eSSL JS-33E Proximity Card Reader | 125kHz Access Control with Keypad
The eSSL JS-33E prox reader is a compact, easy‑to‑install RFID access control unit that combines 125kHz EM proximity card reading with a built‑in PIN keypad. It delivers a contactless yet highly secure entry solution for offices, apartments, laboratories, and commercial facilities. Supporting both card‑only, PIN‑only, and combined (Card+PIN) authentication modes, it offers flexible security levels for different user groups. Its standard Wiegand 26‑bit output ensures seamless integration with any eSSL access control panel or third‑party Wiegand controller, making it a versatile choice for new installations or system upgrades.
📌 What is the eSSL JS-33E?
The eSSL JS-33E is a compact, standalone RFID card reader and keypad designed to provide secure, contactless entry for a wide range of facilities. It operates on 125 kHz EM proximity technology to read standard EM cards and tags, but also supports 13.56 MHz Mifare cards, making it a highly versatile reader for mixed‑credential environments. The unit has a built‑in backlit keypad that allows users to enter a PIN for additional authentication, offering three distinct access modes: Card Only, PIN Only, or Card+PIN (dual‑factor). The readers pass the captured card ID to an attached access control panel via the industry‑standard Wiegand 26‑bit interface, which then decides whether to unlock the door, sound an alarm, or record an event.
Compact in size (114 mm × 45 mm × 18 mm) and designed for indoor use, the JS-33E is an excellent choice for space‑conscious installations such as server room doors, apartment main entrances, office elevator call stations, and laboratory entry points. Its sleek appearance and easy flush‑mount installation make it ideal for reception areas, while its keypad enables you to assign PIN‑only access for service staff or grant dual‑factor access for high‑security zones. The reader supports up to 2,000 users (cards or PIN codes), which is sufficient for small‑ to medium‑sized deployments without the complexity of a full software management system.

🔑 Key Features – eSSL JS-33E Proximity Reader
The JS-33E supports both 125 kHz EM cards and 13.56 MHz Mifare cards, making it a versatile solution for sites transitioning from EM to Mifare technology or that need to support different card families.
Increase security where needed: Card‑only mode for convenience, PIN‑only for temporary credentials, and Card+PIN for high‑risk zones such as server rooms or executive offices. Each mode can be assigned individually to users.
All user credentials are stored locally on the reader. No central software required for daily operation. Administrators can add / delete users, set PINs, and configure door‑open times directly through the keypad using simple programming commands.
Industry‑standard interface ensures plug‑and‑play compatibility with all eSSL access control panels (C3‑100, C3‑200, C3‑400) and third‑party Wiegand controllers. The reader card ID data can be fed directly into access controllers, time‑attendance systems, or ERP platforms.
The door‑unlock relay pulse duration can be programmed from 0 to 99 seconds – ideal for standard entry (“tap and push”) or for automatically opening heavier doors or sliding gates where a longer pulse may be needed.
With dimensions of 114 mm × 45 mm × 18 mm and a low‑profile design, the JS-33E fits easily on standard electrical gang boxes, door frames, or wall‑mount positions without protruding, making it ideal for corridors, lobbies, and elevator‑call panels.
🏢 Where to Deploy the eSSL JS-33E Prox Reader
Secure employee entrances, administrative offices, and server rooms using employee ID cards. The compact size fits flush on door frames; the backlit keypad provides an elegant appearance.
Install at building main entrances, elevator call stations, and community centre doors. Residents can use EM proximity cards, key fobs, or be assigned a PIN for convenient access.
The contactless card reading is hygienic and reduces physical touchpoints. Combined with PIN‑only access for temporary staff, restricted zones can be tightly managed.
Secure laboratory doors, faculty rooms, library entry points, and administrative block doors without the complexity of a full software suite.
Control access to staff‑only areas such as pharmacy back rooms, medical record storage, and restricted‑access corridors.
Rugged enough for temporary buildings exposed to moderate weather; easy to program and reprogram as contractors change, without needing PC administration.
🌟 Why Choose eSSL JS-33E for Your Proximity Card Reader Needs?
eSSL (formerly ZKTeco) has a proven track record in biometric and RFID security. The JS-33E is built on the same reliable technology used in thousands of access control installations worldwide.
The JS-33E‘s 26‑bit Wiegand output ensures seamless integration with any eSSL or third‑party access control panel, biometric terminal, or door controller – whether you are upgrading an existing system or designing a new one.
Most user management (add, delete, change access mode) can be performed directly from the keypad using administrator PINs, making routine management fast and intuitive without requiring a PC or network connection.
Low power consumption (< 30 mA standby) and durable components reduce long‑term operating costs. Optional annual maintenance contracts (AMC) offer ongoing support and peace of mind.
🔌 Seamless Integration with ERP, HRMS & Payroll Systems
The eSSL JS-33E is more than a standalone door controller – its Wiegand output can feed card access events into eSSL‘s eTimeTrackLite software or any ERP/HRMS platform that accepts Wiegand input. Standard export formats (CSV, Excel) and API support allow easy integration with Spine, GreytHR, HROne, Zoho CRM, Candle, Saral, and Oracle. Our integration team can configure event logging, access records, and audit trails directly into your enterprise software, unifying physical security with workforce management without adding extra hardware costs.
