NSF Controls Limited Keighley West Yorkshire BD21 5EF

This indexing mechanism is similar to the Type U described in Bulletin No. RW27 and is designed to

accommodate wafer strut centre dimensions:-

The low friction moulded cam and followers in the assembly ensure a smooth and positive indexing action.

Balanced pressure springs provide consistent and readily reproducible torque values which can be approximated

as:-

This mechanism is also available with panel and spindle seals allowing sealing to 1cm³/hr, and with

6,3mm (0.250”) or 6,0mm (0.236”) dia front shafts.

30°, 36°, 45° and 60° indexing is available for wafers listed below.

Other wafers can also be fitted to the MU mechanism, ask technical sales for further details.

Biasing can also be offered on some MA wafers, details are available upon request.

Imperial (standard).

Bush 3/8” x 32TPI (Whit.)

Shaft 0.25” dia.

Nut 0.525” A/F.

The alternative is optional in each case.

Unless otherwise specified, each switch is supplied with an internal tooth steel lock washer.

An adjustable front stop is available with 30° and 60° indexing providing a quick and easy method of creating

limitations to index rotation. This comprises two washers with a right angled tooth to engage in locating holes

situated in the front plate of the mechanism. the silver coloured washer should be nearer to the mechanism and

thus fitted first. The gold coloured washer is fitted last.
