Z-15GW2255-B Omron

What kind of switch is this?

This is a general-purpose basic switch with a short hinge roller lever actuator. It is designed for mechanical position detection and control in machinery and equipment where a moving part can actuate the roller lever.

What actuator style does this switch use?

It uses a short hinge roller lever with a plastic roller and stainless-steel lever. This style helps the switch respond smoothly to cams, slides, doors, and other moving machine elements.

Is this a drip-proof model?

Yes. This version is a drip-proof type in the Omron Z series. It is intended for applications where added resistance to drips is useful, but it is not a sealed submersible device.

What is the protection rating?

The switch body is rated as a drip-proof model with protection equivalent to IP62, except at the terminals. That makes it better suited to demanding industrial environments than an open basic switch, while still requiring sensible installation practices around liquids and contamination.

What electrical rating should I expect?

This model belongs to the 15 A standard-load family. In the Z-15 series rating table, standard models are rated up to 15 A at 125 VAC for resistive loads, with other AC and DC ratings depending on load type and circuit conditions. For selection, the full application load should always be matched against the switch ratings.

What contact configuration does it use?

It uses an SPDT contact arrangement with common, normally open, and normally closed terminals. This gives flexibility when the circuit needs either make or break operation from the same switch.

Does it use screw terminals or solder terminals?

This version uses screw terminals. In Omron naming, the “-B” suffix indicates a screw-terminal construction.

What is the operating force of the roller lever?

For this short hinge roller lever version, the operating force is up to 1.96 N, with a minimum release force of 0.41 N. These values help when matching the switch to a cam or moving mechanism that has limited actuation force available.

What are the travel characteristics of the actuator?

Typical operating data for this model includes a minimum overtravel of 2.4 mm, a maximum movement differential of 0.8 mm, a maximum free position of 32.9 mm, and an operating position of 30.2 ±0.4 mm. These figures are useful when setting cam travel and installation geometry.

What are the main mounting dimensions?

The switch uses a standard compact body with two mounting holes on 25.4 mm centers. The body length is 49.2 mm, making it suitable for many replacement and retrofit installations where established Z-series mounting patterns are already in use.

What environments is it generally used in?

This style of switch is commonly used in packaging equipment, material handling systems, machine guards, conveyors, and automated mechanisms where repeatable mechanical actuation is needed. The roller lever format is especially useful where the actuator contacts a cam or moving surface.

What is the permissible operating frequency?

For the standard Z-15 family, the mechanical operating frequency is up to 240 operations per minute, and the electrical operating frequency is up to 20 operations per minute. Actual service life depends on load, actuation speed, travel, and environment.

What temperature range is typical for this switch family?

For drip-proof Z-series models, the typical ambient operating temperature range is -15°C to 80°C, with no icing. This allows use across a wide range of industrial environments when the rest of the installation is designed accordingly.

Can this be used for both AC and DC circuits?

Yes, the Z-15GW2255-B is part of a switch family with both AC and DC ratings. However, the allowable current changes significantly depending on voltage, load type, and whether the circuit is resistive, inductive, lamp, or motor load, so the application should be checked carefully before use.
