Product Description:
The VAK41.2F-EN-P-NNNN is an operator input keyboard produced by Bosch Rexroth Indramat as part of the VAK Industrial Keyboards series. Designed for machine consoles and control cabinets, the unit provides alphanumeric and function entry directly into automation controllers, allowing operators to enter commands, menu selections, and parameter values without a separate PC. Its compact build and foil-sealed front make it suitable for panel mounting in production environments where dust, oil, and cleaning agents are common, and it supports direct local input during routine machine operation.
The keyboard operates from a regulated supply of 5 V ±5% and draws only 30 mA, so it can be powered directly from typical controller logic rails without a dedicated supply. Data is exchanged over a Mini-DIN PS/2 interface, which supports connection to legacy HMIs that already use standard PS/2 ports. The keyboard provides 85 keys in a short-stroke matrix, giving users full character access for recipe names, diagnostic text, and menu navigation. Front ingress protection is rated at IP65, so the exposed surface resists dust and low-pressure water jets when the unit is sealed correctly against the panel cutout.
Internal wiring terminates on a header with 6 connector pins, letting the host deliver power and clock/data lines through a single ribbon connection. The keyboard is intended for Pollution Degree II installations, and its faceplate uses Chemical Resistant Polyester Foil that tolerates common cleaning solvents used on shop-floor equipment. While the front is sealed, the rear has a housing protection class of IP00, so it must be mounted inside an enclosed panel. An installation depth of 25 mm helps it fit shallow doors, and the short-stroke mechanism, together with 17 numeric and 4 dedicated special keys, provides crisp tactile feedback during frequent data entry.
