The PWA120 Accessory Adapter enables PFR, PFP, and PFH Series Breadboard Frames to be used with ScienceDesk Workstation Accessories including shelving, component trays, and computer accessory mounts. The adapter is made of durable 0.39" (10 mm) thick steel and is only 7.26" (184.5 mm) long and 5.67" (144.0 mm) wide. Three M16 clearance holes allow Ø1.5" Accessory Mounting Posts to be attached, supporting compatibility with the shelves, components trays, and other accessories below. Four M6 clearance holes are provided for attaching both metric and imperial breadboards, as well as other accessories that mount using 1/4"-20 or M6 cap screws.

• Two Lengths: 750 mm (29.5") or 1000 mm (39.4")
• Ideal for Monitor Mount, Overhead Shelves, or Instrument Shelves
• M16 Bolt Attaches to PWA120 Accessory Adapter 

These 750 mm (29.5") and 1000 mm (39.4") tall posts are used to attach ScienceDesk™ accessories, such as our Monitor Mounts, Overhead Shelves, or Instrument Shelves, to breadboard frames via the PWA120 Accessory Adapter. Each post has a diameter of 1.5", making them compatible with our Ø1.5" post platforms, mounting plates, construction accessories, and V-mounts. A provided M16 bolt is used to attach the post to the accessory adapter.

• Shelves for 900 mm or 1200 mm Wide Breadboard Frames
• Hinged Clamps for Easy Fitting
• 300 mm (11.81") Shelf Depth
• Max Load: 50 kg (110 lbs)

The PSY221 and PSY222 Overhead Shelves span the width of 900 mm or 1200 mm breadboard frames, respectively, and are supported by two 750 mm (29.5") tall ScienceDesk posts (included). Slide the shelf along the post to the desired height above the work surface and then secure it using the hinged clamps. Up to two shelves can be mounted onto a single set of supporting posts, as seen in the image to the right. Additional shelves are sold separately; select the PSY223 additional shelf unit if purchasing the PSY221 overhead shelf and the PSY224 unit if purchasing the PSY222 overhead shelf. All shelves can also be mounted directly to our standard Ø1.5" posts.

Each overhead shelf comes with two hinged clamps for attaching to mounting posts. To install a shelf, secure the clamps at the desired height on the posts. The shelf can then be lowered onto the clamps and attached using the provided M6 cap screws. At this point the shelf can be repositioned or leveled as required. For more details on installation, please see the manual, which is available by clicking on the red Docs icon () below.

Our PSY240 LED light strips or the HDPS12 power outlets can be mounted underneath the shelf using the M6-tapped holes provided.

These Overhead Shelves have a 12º downward tilt allowing for easy viewing, operation, and storage of equipment and accessories in the lab, as shown above. Each shelf has a 2 mm thick steel support bar on the front edge that extends 22.0 mm (0.87") above its surface to securely hold equipment and prevent it from sliding off of the shelf. This bar is attached to the shelf using seven provided screws.

The PSY150 and PSY150/S span the width of a 900 mm wide breadboard frame, while the PSY151 and PSY151/S span the width of a 1200 mm wide breadboard frame. Two 750 mm (29.5") tall posts are included with the PSY150 and PSY151 shelves for direct attachment to the PWA120 Accessory Adapter. If additional shelves are needed we also offer the PSY150/S and PSY151/S, which do not include mounting posts. These additional shelves are also ideal if you wish to use our PSY162 1000 mm (39.4") tall mounting posts (sold separately) instead of the 750 mm (29.5") tall posts provided with the PSY150 and PSY151. Two overhead shelves can be mounted onto a single set of mounting posts. All shelves can also be mounted directly to our standard Ø1.5" posts.

Each overhead shelf comes with two hinged clamps for attachment to mounting posts, as shown in the image to the right. To install a shelf, secure the clamps at the desired height on the posts. The shelf can then be lowered onto the clamps and attached using the provided M6 cap screws. At this point the shelf can be repositioned or leveled as required.

These Instrument Shelves connect to a single Ø1.5" accessory post that can be attached to the PWA120 breadboard frame adapter. The PSY191 and PSY192 each include a Ø1.5" accessory post with the shelf. Smaller in size than our overhead shelves and having a load capacity of 20 kg (44 lbs), these single-post shelves can be used to hold a number of different items. 

The split-clamp design (see the image to the right) allows the shelves to be installed anywhere on the post without removing the existing shelves. Additionally, a PSY322 Hinged Locking Clamp is available, which will hold the vertical position of the shelf on the post while allowing for free rotational movement around the axis of the post.

Each storage tray comes with two hinged clamps for attachment to mounting posts, as shown in the image to the far-right. To install the tray, secure the clamps at the desired height on the posts. The tray can then be lowered onto the clamps and attached using the provided M6 cap screws. At this point the tray can be repositioned or leveled as required.

A 12.7 mm (0.50") high lip on the four edges prevents parts from falling off of the tray, while the 300 mm x 300 mm (11.81" x 11.81") surface provides adequate space to hold needed tools. Each tray comes with a hinged clamp, shown to the right, to attach it to mounting posts. These clamps allow the tray to be installed anywhere on the post without removing the existing shelves. The trays also include a PSY322 Hinged Locking Clamp, which will hold the vertical position on the post while allowing for free rotational movement around the axis of the post.

A 750 mm (29.5") tall post is included with the PSY320 tray to attach directly to the PWA120 Accessory Adapter. If additional trays are needed we offer the PSY320/S, which does not include a mounting post. These additional trays are also ideal if you wish to use our 1000 mm (39.4") tall mounting posts (sold separately) instead of the 750 mm (29.5") tall posts provided with the PSY320. Each components tray can also be mounted directly to our standard Ø1.5" posts.

The locknut on the back of the holder can be loosened to change the angle of the holder. For Ø1/2" post mounting, we also offer the PSX123 Tablet Mount.

A Ø1.5" post (PSY161 or PSY162) is required to secure the PSY121 mount. Alternatively, a post from an Overhead Shelf/Instrument Shelf or one of our Ø1.5" lab posts could also be used.

A 750 mm (29.5") tall post is included with the PSY321 bracket to attach to the breadboard frame via the PWA120 accessory adapter. If additional brackets are needed we offer the PSY321/S, which do not include mounting posts. These additional brackets are also ideal if you wish to use our PSY162 1000 mm (39.4") tall mounting posts (sold separately) instead of the 750 mm (29.5") tall posts provided with the PSY321. Each bracket can also be mounted directly to our standard Ø1.5" posts

The breadboard is mounted to the bracket using six 1/4"-20 (M6) cap screws (not included). For more details on installation, please see the manual, which is available by clicking on the red

• Retain the position of Ø1.5" Post Mounted Accessories
• Hinged Clamb Design Allows for Installation Without Removing Existing Shelves

Thorlabs PSY322 Hinged Locking Clamps are the ideal solution for preventing the unwanted movement of accessories along the axis of the post. Locking the clamp in place (5 mm hex key included) directly under a post-mounted accessory, as shown to the right, prevents the accessory from sliding down the post when it is loosened for adjustments. This also allows mounted shelving or brackets to be freely rotated around the axis of the post to a needed position at any time.
