ZBE101TQ

What type of component is this?

This is a single contact block used in 22 mm pushbutton and pilot device assemblies. It provides 1 normally open contact and is designed for use as a standard control circuit contact element.

What does 1 normally open contact mean?

A 1 normally open configuration means the contact is open in its rest state and closes when the actuator is operated. In practical terms, it allows the circuit to be made only when the associated pushbutton or operator is pressed.

Which operator ranges is it designed to fit?

It is intended for use with Harmony XB4 and Harmony XB5 operator assemblies. If you are matching components within those ranges, ZBE101TQ is used as a front-mounted contact block.

How is the wiring connected?

The unit uses screw clamp terminals. It is suitable for conductors up to 2 x 1.5 mm² with cable ends, or from 1 x 0.22 mm² without cable ends, in line with the stated standard connection details.

Is this a slow-break contact block?

Yes. This contact block uses slow-break operation, meaning the contact changes state as the actuator moves through its travel rather than by a snap-action mechanism.

What is the contact material?

The contacts are made from silver alloy, specifically Ag/Ni. This helps provide dependable electrical performance in general industrial control applications.

What electrical ratings should I check before using it?

Key ratings include a conventional free air thermal current of 10 A, rated insulation voltage of 600 V, and rated impulse withstand voltage of 6 kV. Operational ratings include AC-15 values such as 6 A at 120 V and 3 A at 240 V, along with DC-13 ratings including 0.55 A at 125 V and 0.27 A at 250 V.

Does it include positive opening?

No. This version does not feature positive opening. It is configured as a standard 1 normally open contact block.

How durable is it for repeated operation?

The mechanical durability is rated at 10,000,000 cycles, making it a strong choice for frequently used control stations and operator interfaces.

What are the travel and operating force characteristics?

The contact changes electrical state at 2.6 mm of travel, with a total travel of 4.3 mm. The operating force at the point of NO state change is 2.3 N.

What environmental conditions can it handle?

The contact block is rated for operation from -40 °C to 70 °C and storage from -40 °C to 70 °C. It also has IP20 protection and is specified with TH protective treatment.

How is the block mounted within an assembly?

It is designed for front mounting as part of the operator assembly. This makes it suitable for compact panel control arrangements using compatible 22 mm devices.

What standards and approvals are associated with it?

It is listed against major industrial standards including EN/IEC 60947-1, EN/IEC 60947-5-1, EN/IEC 60947-5-4, UL 508, CSA C22.2 No 14, and relevant JIS standards. The product data also references approvals such as UL, CSA, CCC, DNV, GL, BV, LROS and GOST.

What kind of applications is this contact block commonly used in?

It is commonly used in industrial control panels, machine interface stations, pushbutton assemblies and pilot device installations where a reliable normally open contact is needed for signalling or control functions.
