Heavy-duty limit switch for industrial control

The Telemecanique Sensors ZCKJ404H7 is a rotary-head limit switch designed for surface mounting in machinery applications. It provides 2NC/2NO contact configuration with a 10 A rating at 600 V for both AC and DC circuits. The standard body measures 4.01 in high, 1.57 in wide and 2.36 in deep.

Suits machine builders needing side-actuated

This switch fits equipment that requires a side-mounted rotary actuator without a lever. It carries NEMA 1, 2, 4, 12 and 13 ratings for protection against dust, water and oil. Buyers who need a lever actuator, boot-sealed shaft or a different contact arrangement should look at other models.

Maintains contact integrity during continuous

The 10 A, 600 V contacts are rated for sustained industrial loads rather than momentary signals. NEMA 4 and 13 enclosures resist coolant spray and oil ingress that can degrade performance over long shifts. Surface mounting keeps wiring accessible for routine inspection without removing the switch body.

Questions about this item

What voltage and current ratings must my control circuit stay within for the ZCKJ404H7 contacts?

The switch contacts are rated for 10 A at 600 V AC or DC, so your circuit must not exceed those values.

Can I mount this limit switch on the same surface as older NEMA 1 or NEMA 12 devices?

Yes, the ZCKJ404H7 carries NEMA 1, 2, 4, 12 and 13 ratings, so it shares the same enclosure protection levels as those older units.

How do I verify the rotary head is actuating the 2NC/2NO contacts correctly after installation?

Operate the rotary actuator through its travel and confirm the two normally closed contacts open and the two normally open contacts close at the expected trip point.
