No-Touch Wireless Exit Button 2.4GHz IR Access Control Switch

Asia-Teco CNB-505 Wireless No-Touch Access Control Switch

Upgrade your entry points with the Asia-Teco CNB-505 Wireless No-Touch Access Control Exit Button — a hygienic, touchless door release solution ideal for offices, hospitals, schools, and any high-traffic public space. Simply wave your hand in front of the sensor to trigger the door release — no physical contact required, keeping your environment cleaner and more accessible for everyone.

How It Works

The CNB-505 uses a capacitive sensing chip that detects the movement of electric charge from a human palm. When a hand is held within approximately 2 cm of the panel face, the sensor registers the gesture and activates the relay output — functioning exactly like a traditional push button, but without any mechanical contact. The 2.4GHz wireless connection links the sensor panel to the included receiver, allowing flexible, wire-free placement.

Key Features

• Touchless Operation: Infrared hand-induction sensing eliminates the need to physically press a button — clean, hygienic, and ideal for shared public spaces.
• 2.4GHz Wireless: Wireless transmission between the exit button and receiver for flexible installation without running extra control wires.
• Universal Compatibility: Relay dry contact output (normally open / normally closed) integrates easily with virtually any door access control system, electric strike, or magnetic lock.
• Standard 86-Series Panel: The 86×86 mm form factor fits standard single-gang wall boxes, making installation straightforward in new builds or retrofits.
• Wide Power Input: Accepts AC/DC 12–24V power supply, compatible with most access control power sources.
• Low Power Consumption: Operating current of just 29 mA and quiescent current of 21 mA (at DC12V) for energy-efficient 24/7 operation.
• No High-Concern Chemicals: Contains no hazardous or high-concern substances — safe for indoor installation.

Frequently Asked Questions

Q: Does the no-touch exit button work with all access control systems?

A: Yes. The Asia-Teco CNB-505 features a dry relay contact output with both normally open (NO) and normally closed (NC) modes, making it compatible with the vast majority of electric strikes, magnetic locks, and door access controllers on the market. Simply wire the relay output to your existing door control equipment.

Q: How far does the hand need to be from the sensor to trigger the switch?

A: The induction distance is approximately 2 cm. Hold your open palm within 2 cm of the front panel and the capacitive sensor will detect the charge movement from your hand and activate the relay — no physical touch required.

Q: What power supply does the CNB-505 wireless exit button require?

A: The unit accepts a wide-range AC/DC 12–24V input, which is the standard voltage range used by most access control power supplies. It draws only 29 mA during operation, making it energy-efficient for continuous 24/7 use.

Q: Is professional installation required?

A: The 86×86 mm panel fits a standard single-gang wall box, making installation straightforward for anyone familiar with low-voltage access control wiring. However, if you are unsure about electrical connections, it is always recommended to consult a licensed electrician or security installer.
