This listing is for a T4VH335-11Z-M20 industrial limit switch (selected variant 11Z-M20). Typical electrical details from available references: 230 VAC class rating with switching capacity reported up to about 10 A; the unit uses an M20 cable gland for secure cable entry and carries the 11Z actuator/contact suffix that identifies the contact/actuator variant. Because closely related codes (T4VH, Z4VH, ZR335 and multiple suffixes such as RVA/11Z) appear across listings, confirm the printed model code and actuator type on the part label and photos to ensure correct fit before installation.
