LM2NZF 5.08
LM3RZF 5.08
Double and Triple Level
Printed Circuit Board
Terminal Blocks with
Tension Clamp Connection
Introduction
Weidmuller’s LM2NZF and LM3RZF
5.08mm terminal blocks offer high
packaging density on the printed
circuit board. The new terminals are
quick and easy to install, while
providing secure connections. The
tension clamp terminal blocks are
footprint compatible with Weidmuller’s
double and triple level screw clamp
terminal blocks. This provides the
flexibility of switching between screw
clamp and tension clamp terminals
without changing the existing board
layout, thus allowing freedom of
choice for your application.
The easy and fast operation of the
tension clamp reduces wiring time and
operator strain. The clamp remains
open when activated by a screwdriver,
eliminating the need to maintain
pressure. The self-adjusting tension
clamp maintains the required pressure
on the wire, creating a maintenance
free connection. The clamp is always
closed when not activated, making
incorrect wiring impossible. No
special tools are required since the
wires are easily terminated with a
standard screwdriver.
A marking surface above the wire
entry enables easy and clear
identification of the wiring using
Weidmuller’s KSW marking strips.
Marking is available in standard
number print or customized marking
solutions.
The LM2NZF is offered up to 24 poles
as standard, and can be produced up
to 48 poles. The LM3RZF is offered
up to 48 poles as standard, and can
be produced up to 72 poles.

When mounting PCBs it should be noted that the ratings
specified in the data sheet only relate to connection
elements. The necessary PCBs creepage and clearance
paths must be determined in accordance with VDE 0110.
The current carrying capacity of PCBs is to be observed in
accordance with DIN IEC 326 part 3.
Weidmuller connectors are tested according to the DIN 0627
standard, and are valid for its field of applications. Provided
that the connectors are used for the intended purpose, all
requirements with respect to the occurence of electrical,
mechanical, thermic and corrosive stress will be satisfied.
