SMALL dimensions and high ingress protection are among the demanding criteria limit switches are sometimes required to satisfy.
In response to these needs, Bernstein AG has launched the IF switch range, exclusive to Balluff-Leuze , a new generation of high integrity limit switches.
The very flat design and compliance with the IP67 degree of protection makes them suitable for position detection or limit switching/shutdown in control or safety applications. All the NC contacts are forced disconnect according to EN 60947-5-1.
Bernstein's new IF switches offer extensive switching functionality with slow make/break 1NC/1NO or 2NC contacts or 1NC/1NO snap-action contacts.
The metal actuator head options include: pin plunger, roller plunger (with variable approach direction) or roller lever (with variable approach direction); front-mounted (M14, 21A/F) pin and roller plunger actuators are also available. The mounting plate is also in metal and allows simple and speedy selection of the actuator head approach direction.
All the new IF switches are composed of a high-quality plastic body with either a 2m fixed cable or an AMP4 connector. Two M4 screws are used to mount the switches with adjustment. For safety applications two M5 screws should be used for solid fixing.
