The electronic key switch EKS detects electronic keys (transponders) from a few centimetres distance. This device can replace conventional key switches or key switches with impulse function. Instead of conventional keys, transponders are used for (non-contact) activation of the EKS.
Configuration Options:
- impulse function, 3 seconds impulse time
- impulse function, 0.3 seconds impulse time
- impulse function, any impulse time (relay will give impulses as long as the transponder is presented)
- switch function
- 1 relay (potential-free alternating contact)
- 2 relays (potential-free alternating contacts)
When mounted behind a stainless steel faceplate there is no need for a cutout for the EKS 42 in the faceplate. The reader unit will be fixed at the rear of the faceplate by means of welding studs and the reading area will be marked on the front of the faceplate in any way. This variant is advantageous for example in connection with large push buttons or non-SCHAEFER products to be independent from the design. With no access from the front the device is furthermore safe from manipulation, thus save from vandalism, water and dust.
Note: Including 2 x BlueTag (item number: 009233)

It is basically possible to arrange several EKS units within one fixture. However, the following conditions should be respected:
- installation of EKS 42 VP (vandal-resistant variant behind 2 mm stainless steel) without minimum interspace
