DC 12V Infrared No-Touch Exit Button for Electric Door Lock
DC 12V Infrared No-Touch Exit Button for Electric Door Lock
DC 12V Infrared No-Touch Exit Button — Touchless Access Control
Upgrade your access control system with the Asia-Teco DC 12V Infrared No-Touch Exit Button (Model GH70B/GH80B). Using optical infrared (diffused detection) technology, this contactless exit sensor lets users release an electric door lock with a simple hand wave — no physical contact required. Ideal for gates, office doors, secure entry points, and automation control systems, this switch promotes a cleaner, more hygienic environment by eliminating surface contact entirely.
Key Features
- Touchless Infrared Sensing: Detects hand proximity within 0.1–10 cm using diffused optical infrared technology — no button press needed.
- CE Certified & IP-55 Rated: Dust- and splash-resistant construction makes it suitable for indoor and semi-outdoor installations.
- Stainless Steel + ABS Housing: SUS 304 stainless steel faceplate combined with durable ABS for a professional, long-lasting finish.
- Fail Secure Mode: Maintains the locked state during power loss for added security.
- High-Capacity Relay Output: Dry contact relay rated at 3A / AC120V, DC30V — supports Normally Open (NO), Normally Closed (NC), and Common (COM) configurations.
- Dual LED Indicators: Blue LED = sensor on standby; Red LED = object/hand detected within range.
- Wide Compatibility: Works with most electric locks, magnetic locks, and access control systems operating on DC 12V.

How It Works
When a hand or object is brought within the sensor's detection range, the infrared module triggers the internal relay. The relay momentarily short-circuits the power controller, signaling the electric lock to release. Once the hand is withdrawn, the system re-energizes within the configured delay period, completing the full door open-and-close cycle automatically — all without any physical button press.
Applications
- Office and commercial door access control
- Gate and barrier automation
- Hospital, clinic, and hygiene-critical environments
- Retail entrances and secure exit points
- Smart home and building automation systems

Frequently Asked Questions
Q: What voltage does the infrared no-touch exit button require?
A: This infrared exit sensor operates on DC 12V, making it compatible with the vast majority of standard electric lock and access control systems.
Q: Can this touchless exit button work with magnetic locks and electric strike locks?
A: Yes. The relay output (NO/NC/COM, rated 3A/AC120V or DC30V) is compatible with most electric locks, magnetic locks, and electric strike locks commonly used in access control systems.
Q: What does "Fail Secure" mode mean for this door lock release switch?
A: Fail Secure means that in the event of a power outage, the lock remains in its locked state, keeping the door secured. This is the preferred mode for high-security doors and controlled-access environments.
Q: Is this infrared exit button suitable for outdoor installation?
A: The IP-55 ingress protection rating makes it resistant to dust and low-pressure water jets, making it appropriate for semi-outdoor or covered outdoor locations. It is not rated for full submersion or heavy rain exposure without additional weatherproofing.
