Series 420 - Very short sensors

These devices are distinguished by their extremely short lengths. Introduced by CONTRINEX, these sizes correspond to all relevant standards, with the exception of their length. All devices are available in 3-wire DC, NPN and PNP executions.

Additionally, the range contains devices with 2 wires according to NAMUR (DIN / EN 19234). All 3-wire models are available in N.O. and N.C. configurations; a LED output state indicator is standard. In addition, all the important protection functions are built in, such as short-circuit and overload protection, full polarity reversal protection, induction protection, EMC protection, power-on reset, etc. (only partially for NAMUR devices). CE conformity is achieved without the external protective circuit authorized according to the standard (EN 60947-5-2 / 7.2.3.1).
