AutomationDirect IEC Limit Switches ABP Series

ABP Series Double Insulated Limit Switches

The ABP Series features electrically isolated PBT bodies designed for corrosive environments. These limit switches offer single conduit openings in 1/2" NPT or PG13.5, and splined actuator shafts for fine adjustment. A variety of actuator types are available, including roller levers, plungers, and wobble sticks.

Available Actuator Types and Specifications

Image Description: A series of photographs labeled A through H, showcasing different actuator types for the limit switches, including plungers, levers, and wobble sticks.

Diagram Description: Two diagrams illustrating how to install or adjust the limit switches. The first shows inserting a screwdriver into a hasp to open a compartment. The second shows lifting and rotating a part to open the compartment.

IEC Limit Switches Accessories

Replacement Contact Blocks

Easily-installed replacement contact blocks are available for both heavy-duty IEC and double-insulated limit switches, including mini-DIN models. Note: Limit switches come standard with snap-action contacts. To replace a contact block, remove the limit switch cover, carefully remove the old contact block, and install the replacement. Contact blocks are supplied with an adapter for larger ABM and ABP switches; remove this adapter for mini-DIN AAP models.

Additional Lever Arms, Spare Parts and Accessories for ABM Series

Image Description: Three images showing replacement actuator levers. One labeled AGE52-LEVER is shown installed on an ABM5E52Z11 limit switch. AGE44-LEVER and AGE54-LEVER are also depicted.

Achieve™ IEC Limit Switches Specifications

Notes:

• Minimum temperatures assume a dry atmosphere to prevent freezing.
• Some actuators with heavy springs may not function correctly in a horizontal position.
• Positive opening is ensured by a rigid mechanism that forces the N.C. contact to open if the snap-action mechanism fails. This is generally not considered to work properly with actuators that have flexible components, such as spring or rubber rollers.
• The speed at which snap-action contact blocks are tested has no influence on the switch action. For spring actuators, changeover time may vary from 1ms to 3ms.
• Slow-action contacts require a minimum operating speed to prevent arcing.

IEC Limit Switches Bar Charts

Limit switch types

• Snap action contact: Contact motion is independent of actuator speed, ensuring reliable performance even with slow-moving actuators.
• Slow make/slow break contacts: Contact motion is dependent on actuator speed.

Terminal identification (IEC)

Terminals are marked with two digits. The first digit indicates the pole (circuit), and the second indicates the contact type.

• 11-12: N.C. contact of pole no. 1
• 13-14: N.O. contact of pole no. 1
• 21-22: N.C. contact of pole no. 2
• 23-24: N.O. contact of pole no. 2

Terminal Markings:

Note: Green/yellow wire is physical earth ground. = Contact open, = Contact closed

Contacts Configuration

Z11 Snap Action Contacts (1 N.O. and 1 N.C.):

Make-before-break (overlapping) SPDT: The N.O. contact closes before the N.C. contact opens.

Break-before-make (offset) SPDT: The N.C. contact opens before the N.O. contact closes.

Simultaneous make and break SPDT: The N.C. contact opens at the same time as the N.O. contact closes.

Diagram Description: Bar chart examples showing cam angle (30 degrees) and displacement values in millimeters/cam travel and degrees/lever rotation. Also includes diagrams for plunger travel.

Displacement Values (mm [in] or degrees)

Diagram Description: Images showing the view of a cam insert when looking at the bottom of the head for changeable working heads (E42, E52, E71) models. Instructions are provided on how to change the position by pushing and twisting until it locks into place. Another diagram illustrates positioning at 90° increments and an adjustable lever that can be set from 0-360° with 6° increments.
