Elektrozaczep 50B21 Electric Strike Narrow 6-14V AC/DC Overvoltage Protection TSV

Product Overview

The Elektrozaczep Openers & Closers 6-14V AC/DC (50B21) is a narrow, radial, symmetrical electric strike designed for use in access control systems and door entry setups. Compatible with both AC and DC voltages (6-14V), it is used in commercial and residential buildings for secure door locking with momentary activation. Overvoltage protection (TSV) is included for enhanced system reliability.

The standout feature is the integrated overvoltage protection (TSV), which safeguards the unit from electrical surges, reducing potential maintenance costs and system downtime for installers and facility managers. Its narrow design and 13mm keeper cut-out make it particularly suitable for retrofit or OEM projects where space is limited or specific locking requirements must be met.

Key Features

• Wide voltage range ? operates with AC/DC supply from 6 to 14V


• Integrated overvoltage protection TSV ? prevents damage from electrical surges and spikes


• Narrow, radial, symmetrical design ? fits doors and frames with constrained installation areas


• Keeper cut-out ? 13mm opening for compatibility with multiple lock types


• Momentary activation ? continuous operation up to 1 minute, suitable for access control and timed entry systems


• Maximum lateral load ? 120N for AC (12V), 10N for DC (12V), supporting secure locking under stress


• Nominal resistance ? 8.5 Ohm for efficient electrical performance
