The 3008 "Shorty" roller plunger contact is specially designed for use in security applications where size is a limiting factor. The 3/4" housing makes the 3008 the perfect recessed contact for door jambs with restricted space. Unlike ball rollers, our roller plunger wheel is designed to operate with a smaller surface area in contact with the door’s jambs. This reduces the likelihood that dirt and other debris will clog the mechanism. The tapered wheel allows for more flexibility during installations. The specially designed ABS plastic housing protects the roller wheel from pressure exerted by swelling wood that could cause ball plungers to jam in place.
Use to protect a variety of doors and windows. Can also be used to protect high-value objects on display, such as antiques, rare books or works of art, by placing the object on the recessed contact. The contact housing is made of flame-retardant ABS plastic. The reed switch is protected and held in place by a cyanoacrylate potting material. Roller travel is 1/4" (fully extended to fully depressed).
