IMI STI 2130 Limit Switch for Rotary Actuators

Name: IMI STI 2130 Limit Switch for Rotary Actuators – Brochure & Quote
Brand: IMI STI
SKU: 2130

The IMI STI 2130 is a limit switch enclosure for installation on rotary motion, designed for applications such as on-board pneumatic actuators. The enclosure can house a wide range of mechanical or inductive limit switches, which are prewired to a terminal strip, and a shaft with a manually adjustable cam sets each switch accurately.

Seven Star LLC supplies the 2130 from Muscat. The brochure for this item covers the 2130 limit switch only; a 2030 position transmitter is not described in it.

Limit switch box for single and double acting rotary actuators

The 2130 suits single and double acting actuators and is listed for standard, offshore, sandstorm and copper-free ambient conditions, and for low and high ambient temperatures. Up to four limit switches can be fitted, either mechanical or inductive, with a gold-plated limit switch option. Each switch has an independent, easily adjustable cam for position adjustment, and a robust terminal board with easy access accepts wires up to 2.5 mm2.

The housing is aluminium painted RAL 9005 and carries an ATEX marking printed as EExd II 2 G EEx d IIC T6, with CE and EMC certifications. Protection degree is IP66.

What to confirm before ordering

Because the box mounts on a rotary actuator, send the actuator make and model, the mounting interface, the number of switches and whether each is mechanical or inductive, the switch rating or sensor type required, the electrical supply and the certification requested. The ATEX marking in the brochure uses a legacy designation; ask for the current certificate that matches the unit ordered if your project requires specific certification.

Documents and quotation

To request a quotation for the 2130 limit switch, send Seven Star LLC the full model or order code, quantity, and any nameplate data from an existing unit that is being replaced or matched. Our Muscat team checks the request against the manufacturer document, which can be downloaded from this page, and replies with a formal quotation. Prices, stock and lead times are confirmed per inquiry.

Ordering IMI STI actuators and positioners: what we need

Send the valve torque or thrust, stroke or rotation, supply pressure, fail-safe direction, ambient range and hazardous-area requirement. For positioners add the signal type, and for replacements a photo of the nameplate. The manufacturer's legal entity name, STI S.r.l., may appear on older documents.
