KY2088S IP65 Industrial Keypad With 16 Keys
KY2088S is an IP65 rated 16 KEYS industrial keypad in stainless steel for machinery that gets washed down or works in dusty air. Etched key content is customized rather than printed, so legends survive cleaning chemicals.
Product Overview
KY2088S is an IP65 rated 16 KEYS industrial keypad in stainless steel for machinery that gets washed down or works in dusty air. Etched key content is customized rather than printed, so legends survive cleaning chemicals. It operates from -10℃~50℃, giving headroom in warm plant rooms.
- IP65 rating lets the panel face hose-down cleaning without sealing a separate cover
- Operation temperature up to 50℃ covers hot machine enclosures
- Etched key content resists detergents that strip printed markings
- 16 KEYS in a compact footprint suit mode and code entry on machines
- Durability >2 million keeps service intervals long on production equipment
- USB, PS/2 and RS232 options match both new and legacy controllers
Application Scenarios
- Wash-down food and dairy processing machinery
- Dusty packaging and milling lines
- Outdoor irrigation and pumping control cabinets
- Car wash and forecourt equipment
- Warehouse machinery exposed to airborne debris
Who It Is For
- Food and beverage machine builders
- Process plant maintenance teams
- Outdoor equipment and cabinet manufacturers
- Integrators replacing failed sealed membrane pads
Problems It Solves
- Membrane keypads swell and peel after repeated washing
- Dust ingress makes keys intermittent on open panels
- Printed legends disappear after chemical cleaning
- Warm enclosures push standard keypads past their rated range

How It Compares
| Sealed membrane keypad | A stainless steel face does not swell or delaminate under repeated wash-down |
|---|---|
| Unsealed metal keypad | The IP65 rating allows direct water and dust exposure rather than needing a protective door |
| Keypad rated to 45℃ | Operation to 50℃ gives margin inside warm machine enclosures |
Use Guide
- Fit the supplied gasket evenly to preserve the IP65 seal
- Avoid high pressure jets aimed directly at the cable entry
- Run the unit from 5V±5% with under 150mA available
- Keep ambient within -10℃~50℃ during operation
- Rinse detergents off the panel to protect the brushed finish
