Safety light curtain with muting function from ipf electronic

The safety light curtains (category 4) of the series OY32 (finger and hand protection) and OY36 (body protection) from ipf electronic can be optionally equipped with a muting function. This means that safety light curtains already in use can also be retrofitted.

Muting is a method of automatically deactivating the protective function of a safety light curtain for a short time during a cycle in order to transport goods unhindered into a protected area.

The safety light curtains in the OY32 and OY36 series from ipf electronic can be equipped with the muting relay AO98A980 and muting sensors. If conveyed goods pass a light curtain, the muting sensors must generate a specific signal sequence to start the muting cycle. A person is therefore not able to activate the cycle via the muting relay by intervening or entering the protected field.

Both sequential and cross muting can be implemented with the optional accessories for the light curtains. With sequential muting, several sensors switched in sequence (two before and two after the protected field) are activated one after the other by the conveyed material within the protected field. Cross muting requires only two sensors whose detection range is arranged in a cross shape. The muting cycle starts when both sensors are activated by the conveyed goods.

The maximum permissible duration of the muting process can be set in 10 steps from 10s to infinity. The muting cycle of the light curtains is also signaled via a muting lamp.

The safety light curtains OY32 for finger and hand protection are available with protected field heights of 150 to 1800mm and a resolution of 14mm as well as a range of up to 6m (finger protection) or with a resolution of 30mm and a range of up to 19m (hand protection). The safety light curtains for body protection (OY36) are offered with protected field heights of 500, 800, 900 and 1200mm (range up to 50m), whereby the light curtains integrate 2 to 4 light axes depending on the model.
