Why Choose the EMAS LK10K13 Snap-Action Limit Switch Contact Block?
The EMAS LK10K13 is a durable snap-action replacement limit switch contact block featuring one normally closed (1NC) and one normally open (1NO) contact. Designed primarily for compatible EMAS L4 Series industrial limit switches, this replacement component provides dependable electrical switching for machinery position detection, automation and industrial control applications.
Featuring a short operating plunger and a rapid snap-action switching mechanism, the LK10K13 changes contact state when the associated limit switch actuator reaches its operating point. Its complementary contact arrangement enables electrical position feedback and auxiliary control functions within industrial machinery.
With a 3 A rated operating current at 240 V AC under AC-15 conditions, silver nickel (AgNi) contacts and a minimum mechanical endurance of 10 million operations, the EMAS LK10K13 is designed for reliable performance in demanding industrial environments. Its replaceable construction also supports economical maintenance of compatible limit switch assemblies.

Reliable Snap-Action Switching for Industrial Machinery
The EMAS LK10K13 incorporates a snap-action switching mechanism designed to provide a rapid change of electrical contact state when the associated limit switch actuator reaches its operating point. This decisive switching action is useful in machinery control systems where repeatable mechanical position detection is required.
Its 1NC + 1NO contact configuration provides two complementary switching functions. The normally closed contact can be incorporated into an appropriate monitoring or control circuit, while the normally open contact provides an additional position-dependent signal to a PLC, control relay or other compatible electrical device.
Unlike a slow-action contact block, whose contacts operate progressively with actuator movement, the LK10K13 uses a spring-operated snap mechanism to change contact state rapidly. This makes it suitable for industrial control applications requiring a defined switching transition.
The LK10K13 is primarily designed for EMAS L4 Series limit switches. Its replaceable construction enables maintenance engineers to restore contact functionality while retaining the compatible switch housing and mechanical actuator.
EMAS LK10K13 Compared with Other Limit Switch Contact Blocks
The EMAS replacement contact block range includes several switching mechanisms and plunger arrangements. Selecting the correct variant is important for reliable mechanical operation.
- LK10K13: Snap-action, 1NC + 1NO, short plunger, primarily for L4.
- LK10K23: Slow-action, 1NC + 1NO, short plunger, for L4.
- LK11K13: Snap-action, 1NC + 1NO, long plunger, for L4.
- LK11K23: Slow-action, 1NC + 1NO, long plunger, for L4.
- LK20K13: Snap-action, 1NC + 1NO, short plunger, for selected L1, L2, L3, L5 and L51–L54 limit switches.
For a correct replacement, match the original component's contact action, contact configuration, plunger length and compatible switch housing. A contact block intended for one housing family should not be substituted without confirming mechanical compatibility.
