PLASTIC ROLLER LEVER 2NC NARROW PLASTIC BODY

A Lovato K series limit switch with a roller lever plunger and a self-extinguishing thermoplastic body, built to EN 50047 dimensions with two independent normally closed contacts and one bottom cable entry. The N version ships with the half inch NPT entry that North American conduit work expects.

Why independent contacts change what you can do with it

A limit switch with two NC contacts wired in series gives you one circuit that opens in two places. This one gives you two circuits that open at the same time, which is what you need when one set goes to the control relay and the other goes to a PLC input, or when a machine builder wants the travel signal separated from the stop signal. It costs nothing extra in panel space and saves you a second switch and a second mounting bracket on the machine.

Specifications

Best for: machine builders and maintenance electricians who need two separately wired NC circuits from one travel position, on conduit systems threaded to half inch NPT.

Common questions

What does the N on the end of KBE1D02N mean?
It is the cable entry, not the contact block. Lovato supplies the N versions with a half inch NPT entry as standard, and the catalogue says that dropping the N gives you the same switch with an M20 entry instead.

Are the two NC contacts independent or wired in series?
Independent. The catalogue describes this code as contacts 2NC independent, so you get two separate circuits that open together rather than one circuit looped through both sets of terminals.

Can I use it in a safety circuit as a guard interlock?
Do not assume so. Lovato marks direct positive opening operation against specific contact codes in its catalogue, and this code is not among the ones shown on the page we read. Confirm the positive opening symbol with Lovato before you design it into a guard interlock.

What conduit fitting or gland does the body take?
A half inch NPT fitting, since that is the entry supplied on the N versions. Order the gland at the same time, because the switch ships with the entry threaded and nothing to close it.
