Product Description

The Detect-A-Finger is a cost-effective solution to help protect the operator’s fingers from pinch-point hazards. The Detect-A-Finger® drop-probe devices are used on small machines to protect the operator’s fingers from point-of-operation hazards. The aluminum probe is shaped by the user to fit each application. Additional material, such as acrylic or polycarbonate clear plastic pieces or tube-type materials can be added to the probe to provide adequate protection. When doing this, care should be taken not to add too much additional weight to the probe. Light materials should be used.

These devices are designed to drop by gravity. If a finger or workpiece is in the way of the probe and the probe is not allowed to complete its downward travel, the machine will not start a cycle or stroke. The rotary solenoid, in some units, is in the control box and when energized, after initiation of the cycle, allows the probe to drop. A spring returns the probe to its starting or up position. Another drop-probe device uses interlocking cams in its operating mechanism.

On machines that are mechanically operated, an air cylinder or electric solenoid may have to be added to the operating linkage to trip the machine. On machines that are hydraulically or pneumatically operated, the drop-probe control can usually be interfaced with the existing control system.

When updating machines to meet safety standards, please make sure that each machine is looked at as an individual system that includes, but is not limited to, safeguarding (drop-probe device), machine control, disconnect switch, motor starter, covers for rotating components, auxiliary parts, lockout/tagout equipment, and feeding and retrieving of workpieces.

For Safeguarding Riveters, Eyeletters, Stakers, Staplers, Crimpers, Fastening and Assembly Machines

Many machines can easily be safeguarded with the Detect-A-Finger® drop-probe device.

The control box consists of the probe arm, rotary electric solenoid, relay, limit switch, basic circuit with terminals and other mechanical mechanisms.

Two 18″ aluminum drop-probe rods are furnished with each control box. These rods are shaped by the user to the workpiece or assembly requirements. Read more…

Sequence of Operation

The operator initiates the cycle of the machine usually by an overt action on the foot switch. This energizes the rotary solenoid in the control box, which allows the drop probe to drop until it makes contact with a limit switch. If an obstruction, such as a finger, gets in the way of the probe, the limit switch is not contacted and the machine does not start its cycle. If nothing obstructs the probe and the limit switch is operated, a relay will signal the machine to start its cycle or cause it to trip. Next, the relay drops out, deenergizing the control box solenoid, allowing the probe to move up and out of the way. At this time, the machine completes its cycle and stops. The foot switch must be released and reinitiated to begin another cycle.

The Detect-a-Finger® For Riveters drop-probe device is furnished in two models. Part No. RKC-000 is for mounting on the right side of a machine, and Part No. RKC-001 is for mounting on the left side of a machine.

Select the Detect-a-Finger® For Riveters (right- or left-side mount) that allows the sensing probe to enter the point of operation, without obstructing the work area, and provides for as short and rigid of a sensing probe design as possible. The drop-probe stroke is adjustable from 0″ to 1 5/8″. If needed, add the foot switch below. Complete installation instructions and a maintenance manual are furnished with each device.

Our new, premium solution – the UNITROL SOFT TOUCH Pinch-Point Safety System – is the first and only fully passive safeguarding equipment designed to prevent a pneumatic riveter, welder or other small machine from applying full force if it detects fingers in the machine’s point-of-operation area by measuring electrical continuity between electrodes. If anything other than metal is present between the electrodes, their sensors will not detect continuity and the electrodes will open automatically.
