The N&E modular system
Fewer variants. One system.
Cam systems vary between manufacturers. Even DIN 69638 and DIN 69639 provide for three different systems. Our modular system brings these variants together and reduces the need for extensive spare-parts stocks.
-
A uniform groove rail profile
For clamping U-type and T-type cams. The height of the T-slot bars matches the depth of a U-slot, with reinforcement at the base of each T-rib. Profiles can be placed side by side to create larger groove fields while maintaining 12 or 16 mm row spacing.
-
End cams for mechanical switching
With an approach ramp and mounting hole. Fork-shaped projections engage the central web of the double-T profile to create cams of custom length. Made from surface-hardened steel.
-
Double-T profile for intermediate sections
The drawn steel profile is supplied in metre lengths and combined with two end cams. Users can keep the profile in stock and cut it to the required length.
-
Zinc die-cast end cams
For contactless switching. One end cam creates a short electronic cam; two end cams allow custom lengths.
Designed in detail
Compatible, secure and convenient.
Compatibility
By exchanging two slot nuts, MUE 012-02 for U-slot rails and MTE 012-02 for T-slot rails, N&E cams fit commercially available groove rails.
Ease of adjustment
Scales on both sides allow presetting to 0.5 mm. A conical spring prevents parts from falling out when the screw is loosened, including in vertical installations.
Safety
All cams carry permanent height markings (12.5 mm). Radius end cams also carry a radius marking.
