Membrane Switch Keyboards for Clean Environments
Flat sealed keyboards for pharmaceutical, medical and control rooms where the surface must be wiped down rather than brushed out.
Membrane models use a very thin metal panel with no gaps between keys, so dirt, dust and liquid stay on the surface. They can be cleaned with soapy water, disinfectant or other cleaning agents, which suits pharmaceutical manufacturers and medical equipment builders. Interfaces cover USB, PS/2, RS232, TTL and RS485, with durability rated at 2 million operations or more.
Problems This Range Solves
- Keys with gaps trap product residue that a wipe down cannot reach.
- Disinfectant attacks the print and the seals on ordinary keyboards.
- Cleanroom fascias have very little depth for a keyboard behind them.
- Older control gear still needs TTL or RS485 rather than USB.
Who Specifies It
- Pharmaceutical manufacturers specifying equipment for a controlled area.
- Medical device builders adding a wipeable operator panel.
- Industrial control engineers working to a hygiene protocol.
- Buyers replacing a keyboard that failed after repeated disinfection.
Where It Is Installed
- A 385*110 mm front panel medical keyboard with touchpad on a diagnostic cart.
- A 240*60 mm narrow strip keyboard built into a machine fascia.
- A wipe down station on a pharmaceutical packing line.
- An RS485 connected panel on legacy industrial control equipment.
- A rear mounted membrane panel in a cleanroom enclosure.
What You Get From This Range
- Resistant to dirt, dust and liquid through a sealed flat surface.
- Very thin metal panel design for shallow fascia depths.
- Cleanable with soapy water, disinfectant or other cleaning agents.
- Interface choice of USB, PS/2, RS232, TTL and RS485.
- Durability rated at 2 million operations or more with 220g plus or minus 20g operation force.
What To Specify When You Order
Give us these and the quotation comes back complete rather than with questions attached.
- Confirm which cleaning agents will be used so the surface finish suits them.
- Give the fascia depth available, as the thin panel design is chosen for shallow cut outs.
- Name the interface from USB, PS/2, RS232, TTL or RS485.
- State whether a touchpad is required in the same panel.
- Choose rear or front mounting before the bezel is made.
