A generally oblong mold pressure sensor body containing electrical or mechanical sensing components therewithin actuated by a sensing element or surface on the outside of the body, the sensing element or surface being adapted to engage a mold ejector pin. The sensor body is substantially rectangular in side view and generally peanut shaped in plan view with a relatively narrow waist between forward and rearward lobes. Extending from the forward lobe for engagement with the end of a sensor channel in the mold structure is a tongue of less thickness than the sensor body. The tongue may be removed to change the location of the sensing element relative to the end of the channel in the mold ejector plate. The double lobed sensor body shape provides the stability of a rectangular sensor body in a rectangular channel, however, the lobed body can be slid into and out of a curved blind channel as well as a straight blind channel without disassembly of the ejector plate from the mold. The radius of curvature of the channel need only be greater than the radius of curvature of the waist or neck between the lobes of the sensor body. An alternative embodiment comprises a multiple lobed snap-together chain that can be slid into and out of both straight and curved blind channels.
