Fork sensors
Fork type photoelectric sensors that are rugged, compact and easily installed.
Powelectrics Fork type photoelectric sensors are very easy to use. Thanks to their simple installation, they are particularly suited to use on handling systems and assembly equipment, as well as label readers, or for checking for tearing of web materials. Fork gaps covering the range 2 mm - 225 mm, gating frequencies covering the range 1 kHz - 10 kHz, and "teach-in" versions are available for special applications. PNP/NPN-outputs, light/dark-switching circuitry, and a 25-turn, wire-wound, potentiometer for accurately setting their gating point, are all incorporated in their rugged aluminium housings. Connection is via a jack with an M8-thread. All units are characterized by high stray-light rejection and insensitivity to shocks and vibrations. Special versions equipped with teach-in facilities, wider fork gaps, and capacitive sensing that are capable of reliably detecting metallized labels on transparent films are available for use on labelling systems. Units with 2 mm and 3 mm fork gaps and up to 10-kHz gating frequencies complete the range.
Fork light barriers, F95 series
The F95 series of fork light barriers offer simple and 
accurate adjustment with 25-spin potentiometer so you have no adjustment problems over the 2 to 225mm gap width. The supply voltage is 10 - 30VDC. Indication of the switching state and options for light/dark switching. The light barriers come in a rigid aluminium housing, they have PNP / NPN – output and connections a re via an M8 - connecting plug, 4-pin socket. There are 2 versions, the 400x works up to 1kHz, the 3002 works up to 10kHz.
Fork light barriers, GSI series
The GSI series of fork light barriers are available in gap
widths of 2 to 220mm. There are a number of versions available - red light, infra red and laser. The resolution can be as good as 0.03mm, with reproduceability as low as 0.01mm.
Fork Light Barrier - Label Counter - FA 98 S
With fork widths between 3 and 5mm the FA 98 S fork
light barriers are ideal for use as a label counter. The switching frequency can be up to 10kHz, and there is a simple teach in facility for setting up and adjustment.The fork light barriers come in an rigid aluminium housing, they are easy to mount and offer excellent immunity from interference.
The FA 98 S fork light barriers can also be used for power feed control, overlap detection, detecting marks on transparent layers, crack detection, fine positioning and for counting small objects.
