Bulkey No Touch Button

 

The smallest infrared button in the world!

  • Hygienic – without touch.
  • Easy to install
  • With adjustable sensitivity
  • With adjustable hold time

 

Why Bulkey No Touch?

Miniature size and aesthetic appearance

Bulkey No Touch Sensor is the smallest in the world! Its outer diameter is only 19 mm, and the part that is built behind the board is less than 22 mm. With these small dimensions, it becomes the perfect and convenient sensor for unlocking doors, turning on appliances, turning on / off lights and much more!

Easy Installation

Bulkey No Touch Sensor is extremely easy to install. For your convenience we offer it in two housingс:

  • for built-in mounting – you only need to drill a hole with a diameter of 16 mm to screw the nut on the back.
  • for wall mounting – if you do not have the necessary space to drill the hole, then the metal outer housing of Bulkey No Touch is ideal for you.The housing is clamped externally with 4 wall screws without unnecessary drilling. Fast and easy!

The size of the Bulkey No Touch Sensor allows it to easily replace existing buttons or switches and thus make them more hygienic and aesthetically pleasing.

 

Completely hygienic

Due to the lack of touch Bulkey No Touch Sensor is entirely hygienic. It is suitable for use in rooms where there is a large flow of people or in bathrooms where hygiene comes first. Its typical application is for an exit button when unlocking front doors. It is also suitable as a key for lighting in sanitary facilities in hospitals, polyclinics and other premises.

Adjustable detect range

With the optional IR remote you can quickly and easily change the range of the sensor. It is factory set to 15 cm (11 to 15 cm depending on the reflective surface of the object), but you can change the detection distance from 1 to 15 cm. To protect against unauthorized parameter changes, each sensor is protected with 4 digits access password

Adjustable hold time

With the optional IR remote you can quickly and easily change the retention time. That is, how long the output of the senozra will remain active after detection of an object. It is factory set to 0.5 seconds, but you can change the time to 0.5 to 9 seconds. To protect against unauthorized parameter changes, each sensor is protected with a 4-digit access password

Varieties and models

Select whether you want it to work as a button or a switch

  • BNTxxB – Button type – the output is activated temporarily – while the object is in front of the sensor and a certain time after that. This type is intended mainly for use as a component in access control systems – unlocking / opening doors.
  • BNTxxS – Switch type – the output switches – each time an object is approached, the output changes its state. This type is designed for basic lighting control in kitchens or bathrooms.

Choose the most convenient housing for you

  • for built-in mounting – you only need to drill a hole with a diameter of 16 mm to screw the nut on the back.
  • for wall mounting – if you do not have the necessary space to drill the hole, then the metal outer housing of Bulkey No Touch is ideal for you. The housing is clamped externally with 4 wall screws without unnecessary drilling. Fast and easy!

The size of the Bulkey No Touch Sensor allows it to easily replace existing buttons or switches and thus make them more hygienic and aesthetically pleasing.

used in cases when the controller has an input on “-” to unlock the door.

Example circuit with relay control.

for cases when a higher current needs to be switched or potential-free control contacts are needed, an additional 12V relay is used. BNTxx has built-in protection diodes, which allows direct connection of relays without additional elements. For example, such a relay can be BulKey SKU: BMRM12 – 12V with contacts 240V / 10A
