Telco 4904R0578

The Telco 4904R0578 is the high-gain receiver element of the SG14 Spaceguard light curtain in the leading-edge D-profile housing, with a 4-pin M12 connection and yellow-with-green-stripe color-coding. The SG14 Spaceguard is a self-contained through-beam light curtain; the receiver runs on 12–36 V DC with a short-circuit-protected solid-state relay output, in an IP67 black-anodised aluminium housing with an M12 connection. Its automatic signal-tracking (AST) feature adjusts each channel's sensitivity so no onsite setup is required. It pairs with the matching SG14 D-profile transmitter.
