Logitech Signature M650

The individually reviewed exact source inventory does not identify a sensor model. The published method or description is retained separately.

Adjustable in software, per Logitech.

Logitech does not list a report rate in Hz for this model. · Logitech gives report intervals rather than rates: 7.5 ms over Logi Bolt and 7.5–11.25 ms over Bluetooth (1 ms is listed for the receiver's USB link).

Logitech's sensor description; no sensor model is named. Original manufacturer description: Logitech Advanced Optical Tracking. This identifies optical tracking, not a named sensor model. Model-specific hardware, accuracy and performance are not inferred.

Logitech lists 400 – 4,000 DPI (software).

Logitech lists 101.4 g (3.58 oz) for the standard Signature M650 without stating whether the AA battery is included.

Logitech's listed height (front-to-back in its top-view convention).

Standard Signature M650. Logitech lists height 108.2 mm, width 61 mm and depth 38.8 mm; as in other Logitech records in this catalogue, Logitech's height is the front-to-back length and its depth is the mouse's height. The M650 L and M650 L Left measure 118.7 × 66.2 × 42 mm.

Logitech's listed width; Logitech does not state the measurement basis.

Logitech recommends the M650 for small-to-medium hands and sells a separate M650 L Left for left-handed users; the official views show the back and forward buttons on the left side. Not a grip or comfort test.

Logitech's UK page data give certified post-consumer recycled (PCR) plastic of 64% for the mouse in Graphite, standard size (910-006253), excluding packaging, printed wiring assembly and receiver; the US page gives the same 64% for Graphite 910-006250. Logitech's support specification instead lists the PCR plastic as "Kingfa35%PCR Or Wistron 85%PCR". Both are reported as published; no single recycled-content percentage is recorded as the value.

Logitech lists 5 buttons (left/right click, back/forward, scroll-wheel middle click) plus a connectivity button.

Original manufacturer description: SmartWheel (switches between line-by-line and fast scrolling). Shared SmartWheel availability is comparable; unlisted counterpart horizontal/thumb-wheel details remain unknown.

Logitech rates the silent left/right buttons for 5 million clicks and the silent middle click for 1 million. Logitech's FAQ says its SilentTouch technology reduces more than 90% of the clicking noise compared to Logitech M185; its feature text says SilentTouch reduces 90% of click sounds. No decibel figure is published. Original manufacturer description: Silent left/right clicks and silent middle click. These own claims do not establish a measured noise advantage over another quiet-click mouse.

Wireless range 10 m, per Logitech.

Logitech's ratings; test conditions are not stated.

Original exact supported software description: Logi Options+ (Windows 10 or later and macOS 10.15 or later). Support separates software support(Windows10+/macOS10.15+) from deviceOS/platform support; at-release app is Options+ onWindows/macOS. Tune support is not resolved, and these source details do not establish a peer incompatibility.

Logitech's OS/platform support; Bluetooth use needs macOS 10.15 or later. Logitech says it is Works With Chromebook Certified. Logitech's own sources disagree on minimum versions: the support specification and the UK page's system requirements give iPadOS 13.4 or later and Android 5.0 or later (recorded here), while the UK page's FAQ says it natively supports iPadOS (14 or later), Android (8.0 or later) and Linux.
