TP211 family
Touch & Proximity Sensing Switches,
with Stainless Steel Faceplate
Features
- Operates with the lightest of touches, or close hand proximity, through gloves and other clothes, and through glass, etc.
- Window-mount units are supplied with high-performance double-sided-adhesive and are suitable for operation through single and double glazing. (Not suitable on windows with a metallic coating)
- Window-mount units are vandal-proof - installs to inside of the window !
- Wall-mount units are vandal-proof - all components are behind the solid metal touch faceplate
- Attractive brushed stainless steel faceplate
- Entire faceplate is sensitive
- Different sensitivity settings via jumper - allows choice of touch or proximity activation
- Fast activation, ideal for fast egress
- Ideal for elderly and disabled - no pressure required, operates with the lightest of finger touches, or just a nearby wave of the hand
- Perfect for installations that need to comply with the Disabilities Discrimination Act (DDA)
- 'Fit and forget' technology. Fully self-calibrating, for life!
- No moving parts - no buttons to break
- Flush or surface mount options for wall mount units. Brushed aluminium surface collar(1GSLV) available separately for surface mounting
- LED indicator and built-in sounder provide visible and audible feedback. Sounder can be disabled by removing jumper

Sporting a smart, brushed, stainless-steel faceplate, these touch sensors offer a robust alternative to call switches and door release buttons. Available as window mount and 1 gang flush/surface wall mount, the TP211 family of touch switches detect a person's touch and activate an on board relay that can be used to operate an external sounder, an automatic door opener, provide an egress signal to an access control system, operate a light, etc. An internal sounder and bright LED on the faceplate acknowledge the caller's touch with both audible and visual feedback.
No pressure is needed to activate the sensor because the lightest touch or close-proximity of a human body is sensed electronically, by a PCB mounted on the rear of the faceplate, using the same projected capacitive (PCAP) sensing technology used in the touch screens of smartphones. Unlike a conventional push button, there is no need to apply pressure in a specific small area and direction because the entire faceplate is sensitive. The lightest touch anywhere on the faceplate will activate it, a boon for both disabled and elderly. The TP211 is proximity sensitive too and can be activated through clothing or with a simple hand wave in front of the faceplate.
There are many applications that benefit from these features.
The NHS has made significant progress in reducing the spread of viruses and superbugs in hospitals.
The TP211 stainless steel faceplate is plain and flat, with the notable absence of any protruding button, making it quick, extremely easy to wipe clean and able
to withstand cleaning products.
This alone is an aid against the spread of viruses, but the sophisticated proximity
sensing capability of the TP211 also allows it to be activated by an approaching finger before the faceplate is actually touched.
This is a major leap forwards in combating the spread of MRSA and other superbugs.
Flu and other viruses are spread by people touching a transmission surface previously touched by an infected person. Door handles and door release buttons
are such transmission surfaces. Through the use of the TP211 and automatic door openers, the spread of virus via these transmission surfaces can be eliminated.
People no longer need to push the door release button because a finger tip within a centimeter of the TP211 faceplate is sufficient to open the door, no physical contact is necessary.
A person carrying keys can use them instead of pointing their finger close to the sensor because the TP211 senses their body through the metal of the key.
People carrying a tray can use the back of their hand, or even their posterior. The TP211 will sense the human body through clothes too. Surgeons and other medical staff whose hand cleanliness is paramount, need not touch the sensor. They could present their forearm close to the sensor to activate it.
The fast response time of the TP211 and its ability to detect a finger or hand wave in front of it make it perfect for fast and easy egress. This is useful in office buildings where people need to frequently open doors protected by access control systems. It is also a benefit in factories where workers need to move swiftly between rooms with automatic door openers. Unlike conventional button operated door releases, there is no button to get broken when people hit it too hard or simply due to sustained and frequent use.
The TP211 is also being used in secure units where its simple flat, robust design is a benefit against vandalism.
Using 'fit and forget' technology, these touch switches are fully self-calibrating for life and have no moving parts.
The flush wall mount units attach to a 1-gang electrical box/pattress, can be surface mounted using an optional brushed aluminium collar, and are virtually vandal proof due to the simple, flat, robust design of the faceplate.
The faceplates of the glass mount units have no mounting holes, but are attached using thin, double-sided, high-performance adhesive(supplied). Alternatively, for an even stronger bond, a glass to metal adhesive can be used, such as Loctite 319 rear view mirror bonder. They are attached to one side of the glass and sense touch, through both single and double glazing, from the other side of the glass. This allows a vandal proof installation to the secure side of a shop window while detecting callers when they touch the glass from the outside, opposite the faceplate. The TP211 senses the touch right through the glass, even with a gloved hand.
